Echotel Models 940 and 941 are compact integral units that utilize pulsed signal technology to perform high or low level measurement in a wide variety of liquid applications.
Measurement Principle:
High frequency 2 MHz ultrasonic pulses are transmitted across a transducer gap in the presence of a liquid medium, but are attenuated when the gap is dry.
Features:
Advanced transducer design provides reliable operation by draining viscous liquids and ignoring foam in turbulent applications
Extremely compact unit is easily installed in areas where access space is limited
No calibration or configuration necessary
1 amp SPDT relay output (940), 8/16 mA current shift output (941)
