Echotel® Model 344/345 Ultrasonic Non-Contact Transmitters
Models 344 and 345 are full-featured, ultrasonic non-contact transmitters that provide continuous measurement for liquid level, volume, or open-channel flow applications. Their measurements are not affected by changes in specific gravity, viscosity, or conductivity.
Measurement 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.
Features:
Front panel keypad for ease of programming
4-20 mA isolated and RS-232 outputs
Four 10 amp SPDT relays
Password protected access
16-character alphanumeric display of all parameters
