Five Main Components to All Flat Glass Gauges

Chamber: Center of the gauge, and is the part that primarily contains the process fluid. It is machined from bar stock. The gasket seat is recessed for lateral support, and easy positioning.
Glass: Provides the visual interface between the process fluid and the outside.
Cover: Protects the glass, and provides the compression surface for sealing the gauge. The cushion seat is surfaced for lateral support and easy positioning.
Gasket/Cushion: Provides for a seal between the chamber and glass (gasket), and protects the glass from mechanical stresses from the cover (cushion). For a given gauge, the gasket and cushion are normally the same material.
Bolts/Studs/Nuts: Provides a uniform compression load to the gauge for pressure sealing.

Reflex Style Level Gauge

Reflex gauges have a single piece of glass, mounted on one side of the chamber. This piece of glass is flat on the outside, and has a series of prisms on the inside, facing the process fluid. When light strikes the portion of the glass covered by a liquid, the light is reflected from the back of the chamber. This area appears “black”. When light strikes the glass where no liquid is present, the prisms reflect the light directly out of the gauge. This area appears “silvery”. Reflex gauges provide an excellent way to measure clear, or difficult to see fluids. The “silvery”/”black” interface is easy to see from several feet away.

Why Use Flat Glass Gauges

Flat Glass Gauges have been in use for over 100 years. They give you the ability to directly view the process fluid under temperature/pressure conditions that would render most other level technologies useless. Their construction is very robust, and reliable. They define the term “simple to use”. After installation, the only tool you will need is your eyes. Flat Glass Gauges are relatively inexpensive as compared to most other level technologies.

Other Features

They do not need electrical power to operate. This can be a great advantage in the case of a power outage.
Simple to install – no calibration is necessary.
Can be used as a reference to check, or calibrate, other level technologies.
Pressure rating from vacuum to 4000psig.
Temperature rating from -150°F to 750°F
Not affected by the chemical or electrical properties of the process liquid. Specific gravity, dielectric, conductivity, surface turbulence, vapor, foam, etc. no longer needs to be considered.

Flat Glass Gauges vs. Tubular Glass Gauges

KENCO offers a wide range of Flat Glass Gauges and Tubular Gauges. With all of those choices, one of the basic questions is, “Should I use Flat Glass or Tubular Glass gauges?” The answer is fairly simple. If the process pressure is under 500psig and the process temperature is under 400°F, tubular style gauges should be considered. KENCO tubular gauges shield the glass on all four sides to virtually eliminate glass breakage, and tubular gauges are even more cost effective than flat glass gauges. Regardless of the style chosen, KENCO’s high quality gauges will provide you with many years of reliable service.

Medium Pressure Flat Glass Gauges

KENCO Medium Pressure Flat Glass Gauges are versatile enough for most common process conditions. Standard carbon steel gauges meet the requirements of NACE MR0175. Unlike other manufacturers, there is not additional charge for NACE. All materials meet or exceed ASTM specifications. Model KMR Reflex Gauges can reach process pressures up to 3000psig. Model KMT Transparent Gauges can handle pressures up to 2000psig. While these gauges are not specifically designed for steam service, the Model KMR gauges will perform at saturated steam pressures up to 300WSP. The Model KMT will perform at saturated steam pressures up to 600WSP, depending upon gauge size. Mica shields are recommended for Model KMT when used in steam. Shields cannot be used with Reflex Gauges.

High Pressure Flat Glass Gauges

KENCO High Pressure Flat Glass Gauges have a superior rugged design for the most demanding process conditions. Standard carbon steel gauges meet the requirements of NACE MR0175. Unlike other manufacturers, there is no additional charge for NACE. All materials meet or exceed ASTM specifications. Model KHR Reflex Gauges can reach pressures up to 4000psig. Model KHT Transparent Gauges can handle pressures up to 3000psig. While these gauges are not specifically designed for steam service, the Model KHR gauges will perform at saturated steam pressures up to 300WSP. The Model KHT will perform at saturated steam pressures up to 750WSP. Mica shields are recommended for Model KHT when used in steam. Shields cannot be used with Reflex Gauges.

Flat Glass Gauge Valves (Gauge Cocks)

KENCO Gauge Cocks are designed for use with KENCO Flat Glass Gauges, or gauges from any other manufacturer. All valves are “Offset Pattern” design. This provides for gauge connections that are offset 0.875″ from the centerline of the vessel connections. This allows the gauge to be cleaned by removing vent/drain plugs from the valve. All materials meet or exceed ASTM specifications.

Other Gauge Accessories

Frost Proof Extension
The KENCO Frost-proof Extension is used in low temperature applications where frost has a tendency to build up on the gauge. This extension prevents frost from covering the window, maintaining visibility at all times. The Frost-proof Extension consists of clear, plastic block that is in direct contact with the glass, and extends beyond the cover so that frost build-up does not block the glass. Mounting is easy, and can be added to any Reflex or Transparent gauge in the field. The extension can be installed or removed for cleaning while the gauge is in service.

Gauge Glass Options
KENCO supplies tempered borosilicate glass as standard in all Flat Glass Gauges. Borosilicate glass is suitable for most chemicals, and is good for temperature ranging from -425°F to 600°F (glass rating only). The tempering process improves the thermal shock resistance of the glass. Aluminosilcate glass is offered as an option for higher temperature applications. It offers less thermal expansion, as compared to borosilicate glass. Aluminosilicate glass is good for temperatures ranging from -425°F to 800°F (glass rating only). However, due to the added cost, it is only recommended for temperatures from -600°F to 800°F.

Glass Shields
For corrosive or steam applications, KENCO offers shields to extend the life of the glass in transparent gauges. The shields are made from either PCTFE (Kel-F) or Mica. Mica shields are recommended for steam service. Kel-F shields should be used in corrosive fluid applications. The shield is placed on the process side of the glass. Shields can only be used with transparent gauges.

Thermal Insulators and Gauge Scales
KENCO offers a wide variety of methods to heat or cool gauges in order to maintain the temperature of the process in the gauge. Internal & external heating/cooling tubes, thermal jackets, and insulation blankets are available. Gauge scales can be supplied to provide a numerical reference to the level being measured. Contact KENCO for more information.

Transparent Style Level Gauge

Transparent gauges have two pieces of glass on opposite sides of the chamber. Light enters the gauge from one side, and the level is viewed from the other. Transparent gauges are useful when the actual liquid characteristics need to be seen. They are also commonly used for liquid-liquid interfaces. Mica shields can be used in transparent gauges to protect the glass in steam environments. Kel-F shields should be used in corrosive environments.

Magna-Site™ Magnetic Level Gauge

The KENCO Magna-Site™ is a magnetic liquid level indicator used to determine the volume of liquid contained within a vessel. Because the Magna-Site™ eliminates the need for glass, high pressure applications and hazardous locations are protected from the danger of a chemical spill due to potential glass failure.

The KENCO Magna-Site™ utilizes three major components: the gauge housing chamber, the magnetic float and the magnetic flag assembly. The gauge housing chamber is mounted adjacent to the side of the vessel. It is constructed to withstand the same temperatures and pressures as the tank itself. It is equipped with the appropriate tank mounting connections for easy installation and to allow equalization of liquid level in tank and gauge.

Inside the gauge housing chamber is the magnetic float, which contains radially-positioned magnets to provide a 360° magnetic-flux field. Each float is internally weighted based on specific gravity so that the liquid level in the gauge coincides with the location of the magnets inside the float. Attached to the gauge housing chamber is the magnetic flag assembly. This is the visual means of liquid level indication for the KENCO Magna-Site™. The assembly is made up a of a series of bi-colored fluorescent flags. As the magnetic float rises and falls with the liquid level in the gauge housing chamber, a magnet embedded in each flag reacts to the 360° magnetic flux of the float. This magnetic interaction causes each flag to rotate 180°. The flags below the magnetic flux of the float will flip to fluorescent green, while those flags above the float level remain steel gray.

Features

Maximum safety — No glass is used in the construction.
Optimum visibility — Fluorescent flags are visible from great distances
Float with 360° magnetic flux — Maintains a strong magnetic field in all directions; turbulent liquids will not cause flag assembly to give an inaccurate level indication
Double flag protection — Flags are hermetically sealed inside a PTFE encapsulated assembly which is shrouded by a 300 series stainless steel enclosure on three sides with a UV stabilized high-impact clear polycarbonate shield
Adjustable viewing angles — Flag assembly can be rotated to any angle to provide maximum visibility
Multiple mounting options — Engineered construction allows for a variety of mounting configurations
Compatibility — A broad range of materials can be used to withstand harsh chemicals
Remote level indication — Explosion-proof magnetostrictive level sensor/transmitter provides a 4-20mA signal output
Height scale — 304 stainless steel with no. 3 finish and large etchedcharacters/lines for easy reading
High/Low level switches — Explosion proof switches can signal an alarm, operate a pump/valve or act as an emergency shut down
Convenience — Easy installation and very low maintenance
Warranty — Three year guarantee against defects
Reliability — KENCO has been building magnetic liquid level indicators since 1986

KENCO Magnetostrictive Transmitter

KENCO loop powered transmitters electronically monitor the location of the magnetic float within the Magna-Site gauge housing, providing an output in a unit of measure, as a percent of span or a 4-20mA output. The transmitter is available up to a length of 300 inches. Zero and span may be adjusted by using the HART® communications protocol or it may be manually calibrated using the keypad display inside of the explosion proof housing. These transmitters operate within a process temperature range of -40°F to 300°F. Field replaceable electronics are potted and encapsulated. KENCO transmitters are available as standard with NEMA 4X/7 explosion-proof housings. These housings feature an industrial epoxy coating for corrosion resistance. All KENCO level transmitters use non-contacting, magnetostrictive technology. This simple design ensures no scheduled maintenance or re-calibration — ever. Accurate, non-contact float location sensing is achieved with absolutely no wear to any of the sensing elements.

Principle of Magnetostriction

The level transmitter is composed of two concentric members. The outermost member is a protective stainless steel chamber that withstands aggressive or harsh process industry environments. The heart of the transmitter design is the innermost member, the waveguide, a formed element constructed of a proprietary magnetostrictive material.

A pulse is induced in the waveguide by the momentary interaction of two magnetic fields, one from an electric current pulse launched along the waveguide and the other from the magnet inside the float. This interaction produces a strain pulse that travels along the waveguide. The location of the magnet inside the float is determined by measuring the elapsed time between the launching of the electronic pulse and the detection of the strain pulse by the sensor head. The time period measurement is used to produce a 4-20mA output.

Float Characteristics

360° magnetic-flux field provides constant interaction with flag assembly in turbulent liquids
Internally weighted based on specific gravity so that location of magnets
Inside float coincide with liquid level in gauge
Cylindrical geometric shape ensures more accuracy in interface specific gravity applications
Rare earth magnet assembly has an unusually high energy output volume and is highly resistant to demagnetization; they will not demagnetize at high temperatures like ceramic magnets
Standard float material is 316 stainless steel. Other float materials available, including: Titanium, Hastelloy™, Inconel™, Alloy 20, Aluminum, PVC and CPVC
Standard float good to a minimum specific gravity of 0.50. Custom floats for lower specific gravities available
360° magnetic-flux field is ideal for interaction with KENCO magnetostrictive transmitter
Float is non-vented, so vapors can not condense inside float
Compact length minimizes ground clearance requirements

High-Temperature Flag Assembly Features

Maximum constant temperature of 800°F
Flags are 316 stainless steel
Flag color is heat cured at 400°F with heat resistant paint
All 300 series stainless steel flag assemblies are ideal for severe environment
Alnico 8 magnets are nickel plated to withstand severe environments

Features

Applications

The 5700 Series Gauge provides a visual means for checking the contents of a bulk tank and a means for checking the injection rate of a chemical metering pump. The gauge is designed to operate in low to medium pressure applications up to 500 psig.

Gauge Features

The sight tube of the 5700 Series Level Gauge is completely protected. Three sides of the gauge are protected with a metal frame, while the face of the gauge is protected with a polycarbonate shield. This shield can be custom calibrated to read tank volume or any other calibration. Refer to the Product Specifications tab to see the assortment of standard shield options. For mounting purposes, a mounting lug is welded to the back of the gauge. The standard sight tube is glass; other sight tube materials are available, along with a wide option of O-ring seals. The gauge is fitted with 1/2″ MNPT x 3/8″ FNPT connections.

The One Minute Test

The injection rate is checked by closing a valve between the gauge and chemical storage tank and observing the change in fluid height in one minute. Using the rate scale on the front of the polycarbonate shield, count the number of marks the fluid level passed in the one minute test period. This will give you the actual chemical pump rate. If the rate is not the one desired, make an adjustment to the chemical pump feed rate and conduct as many one minute tests as is necessary to set the chemical pump rate to the rate desired. If a higher pump rate is required, the test period can be shortened to 30 seconds or 15 seconds.
