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. Literature
Additional Tools:
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:
Pulsed electronics for excellent performance in difficult process conditions and superior immunity from sources of electromagnetic noise
Advanced transducer design provides reliable operation by draining viscous liquids and ignoring foam in turbulent applications
Suitable for SIL (Safety Integrity Level) 2 loops (FMEDA analysis data available)
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)
Applications:
OEM products
Seal pots
Compressor and oil lubricant skids
High or low level alarm
Pump protection
Fill line monitoring
Options:
NPT, ANSI flanges and Tri-Clamp sanitary fittings available
Available in lengths from 1 to 100 inches (3 to 250 centimeters)
