Increasing demands for compliance with safety systems and overfill protection have mandated more reliable point level measurement. Echotel® Models 961 and 962 ultrasonic level switches meet these demands with advanced transducer designs, extensive hazardous location approvals, and a new self-test technology.

Single Point

Echotel Model 961 offers the ultimate solution to reliable single-point liquid level measurement. This advanced switch uses pulsed signal technology for superior performance in difficult process conditions, and to provide excellent immunity from sources of electrical noise interference. Extensive self-testing of the electronics and transducer make this advanced switch suitable for use in Safety Integrity Level (SIL) 2 loops.

The Echotel Model 961 is equipped with advanced diagnostics that continuously check the sensor and electronics. The diagnostics also alarm for electrical noise interference from external sources.

Dual Point

Echotel Model 962 is a dual-point switch that can be used as a level controller, or to control pumps in an auto fill or auto empty mode. The tip sensitive lower gap performs well in aerated or foamy liquids, and can measure to within 1.4" of the vessel bottom. The rigidity of the unique flow-through upper gap allows separations of up to 125" (318 cm) between the upper and lower transducer gaps.

Echotel® Model 355 is a loop-powered, non-contact-type ultrasonic transmitter that performs liquid level, volume or open channel flow measurement. HART® communications are offered with a PACTware™ PC program for remote configuration and troubleshooting.

Radar has been part of the level measurement market for more than thirty years. The early designs used in tank gauging were heavy, expensive, power-hungry and complex. Advancements in radar circuitry have evolved the modern radar transmitter so that now it is light, inexpensive, loop-powered and easy to use. The R82 is the logical extension of that evolution.

Microwave-based radar is a superior measurement technology with its ability to operate effectively in a wide range of process conditions. It has been too expensive to use as a replacement for ultrasonic transmitters in simple, daily applications...until now. The R82 radar transmitter can be considered the answer to almost every daily level measurement application imaginable.

The Pulsar^® Model R86 non-contact radar level transmitter is a 24 VDC, liquid level transmitters. It has a longer measurement range, circular polarization, advanced diagnostics and is easier to use than most loop-powered radar transmitters.

The Pulsar^® Model R80 radar transmitter is the latest generation of Magnetrol^® 24 VDC, loop-powered, non-contact radar transmitters. Utilizing Frequency Modulated Continuous Wave (FMCW) radar technology, this transmitter offers enhanced performance, proactive diagnostics, and various configuration wizards to bring simplicity to an often complex technology.

The Pulsar^® Model R96 is a loop-powered, 24 VDC, non-contact radar level transmitter. It has a longer measurement range, improved diagnostics and is easier to use than most loop-powered radar transmitters.

The Thermatel^® Model TD1/TD2 switch is utilized in flow, level and interface applications. The TD1/TD2 is popular for pump protection, specifically low flow detection with the unique spherical tip design, to prevent pumps from running dry. Continuous diagnostics with fault indication, temperature compensation and fast response time make the TD1/TD2 the latest in thermal dispersion technology.

Thermatel^® TG1/TG2 provides a two-wire, intrinsically safe circuit between the probe and remote din rail enclosure. The flow/level/interface switches provide a new level of performance and reliability not found in previous switches. Continuous diagnostics with fault indication, narrow hysteresis and fast response time make the TG1/TG2 the latest in thermal dispersion switch technology.
