ISE-Magtech has established itself as one of the world's leading suppliers of magnetic level gauges. Originally designed to replace old-style sight glasses, magnetic level gauges have quickly become the popular choice for non-invasive level control.

ISE-Magtech gauges are easy to install and virtually eliminate high maintenance costs associated with sight glasses, displacers, etc.

Some of the more common applications include replacing old style displacement transmitters in oil field service; replacement of sight glasses on high pressure service in power plants is also typical. Magnetic gauges are ideal for use in corrosive service where other level gauges are too costly or just unavailable.

With the addition of level switches and transmitters, which simply clamp to the gauge, ISE-Magtech offers complete level indication and control with minimal modifications to the tank.

Magnetic Level Indicators

Continuous visual indication from 100 feet or more!

Eliminate dangers from broken sight glasses

Hermetically sealed indicator does not contact process fluid.
Choice of mounting styles and special materials: stainless steel, CPVC, Kynar, Hastelloy, Monel and others.
Safe for flammable, toxic and corrosive fluids at high pressures and temperatures.
Ideal for interface measurement.
FM, UL & CSA listed clamp-on alarm switches & 4-20mA X-mtrs.
Welding specs to Boiler and Piping Codes ASME-B31.1 / B31.3. 3A
Approved for sanitary service.
Magnetic flippers or continuous follower.
All floats with 360 Deg. concentric magnet assembly.

Description:

The float chamber is basically a column of 2-1/2 inch pipe with process connections to match those of the storage tank, reactor, or other equipment where level is to be measured. These connections may be side couplings or flanges, or top and bottom flanges.

The magnetic float moves up and down inside the chamber as the process level changes. Float type is determined by the process fluid, light enough to maintain buoyancy and have properties that allow it to withstand the temperature and pressure combination.

Contained inside the sealed float is a 360 deg. magnet assembly. The indicator tube and scale assembly are attached to the float chamber (standard scale is in feet and inches). The indicator tube is available in polycarbonate or glass (temperature limit on polycarbonate is 250 deg. F).

 

Principle of Operation:

Inside the indicator tube is a lightweight magnetized indicator or series of metallic flags. The indicator is magnetically coupled to the float and moves up and down with the liquid level. The indicator allows the operator to read the level from more than 100 feet away. The only moving parts are the float and the indicator.

Specifications:

Material: All wetted parts and external metal parts are stainless steel.Indicator tube is glass or polycarbonate.

Float Chamber: 2-1/2 inch pipe with RF slip-on/blind drain flange (standard)

Indicators: 7/8 inch diameter by 1-1/4 inch long, brightly colored flourescent red follower or the optional Bi-colored Flag "Flipper" Style indicator.

Continuous Scale: Feet and inches standard with 1/2 inch scale divisions, or metric; resolution approximately 1/4 inch (Custom scales also available)

Pressure Rating:

Minimum Specific Gravity: 0.25

Temperature Rating: -200 to +1100 deg. F (-128.9 C to +593.3 C)

Note: All LG-Series gauges are hydrostatic tested to 1.5x the pressure rating.

Magnetostrictive LTM100 Level Transmitter

 

Features and Benefits

Precision Accuracy up to .01% F.S. (.005% Repeatability).
Dual 4/20 mA output (simultaneous) for level and interface or level and temperature.
Smart Transmitter with HART protocol.
Mounts from tank top or externally to mag gauge.
Diagnostics with field replaceable electronics.
No maintenance or recalibration required.
Field Adjustable Zero Span
FM, CSA & CENELEC certified.

The LTM Series Magnetostrictive level transmitter may be used as a stand-alone top-mount level transmitter or may be mounted externally on the LG Series mag gauge. It is typically used in applications where precision accuracy / high repeatability is required. The unit offers plug & play HART protocol with the two-wire 4-20 mA output, and has an optional second 4-20 mA output for interface levels or temperature.

The LTM transmitter consists of a sensor tube (typically 5/8"-316SS) which houses the waveguide and temperature sensor. The waveguide is made to order in lengths up to 30 feet. A low-power microprocessor circuit, housed in an explosion proof condulet, is used to generate a current pulse down the waveguide. Liquid level is detected when the magnetic field from the float interferes with the current pulse signal.

** Quotation Request ** ** **

Other features include a variety of material options including Hastelloy, Monel, Kynar, etc. Field calibration is simple with on-board zero/span pushbuttons or with conventional HART hand-held calibrators. Installation requires standard conduit piping procedures and a variety of mounting configurations are available. When used with the magnetic level gauge, it simply clamps to the side of the gauge chamber and is ideal for high pressure / high temperature applications.
