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.
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.
