Model 355 Two-wire Loop-powered Ultrasonic Non-contact Transmitter
Echotel 355 is an integral mount, high performance ultrasonic non-contact transmitter for liquid level, volume and open channel flow measurement. The electronics are housed in a single compartment cast aluminium or Lexan housing. The intelligent electronics analyse the ultrasonic echo profile, apply temperature compensation, reject echoes from false targets, and then processes the true echo from the liquid surface. This results in an extremely reliable measurement even when application difficulties like turbulence and false echoes exist.
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.
Operating Principle
Ultrasonic pulses are emitted from the transducer, and the time required for the echo to reflect from the liquid surface and return to the transducer is measured.
