ECHO Process Instrumentation, Inc. products

The ECHO LEVEL HUNTER III is an advanced, low cost, ultrasonic level measurement system that utilizes the latest state-of-the-art technology to provide reliable measurement and control. It can accurately measure level and volume (pre-configured tank shapes) and perform alarm and fixed pump control for up to 4 pumps. Standard features include: 1 4-20mA output, 4 SPDT Relays, LED’s for alarm/pump status and Quick Setup menu-driven programming. It also comes standard with a RS-232 serial communication port and optional RS-485.

Submersible Pressure Transducers for water depths up to 2,000 feet. The Oyster 700 Series provide accurate and reliable level measurement utilizing the latest miniature microprocessor technology. The transmitter contains a piezo-resistive sensor that outputs a signal proportional to the hydrostatic pressure on the diaphragm. This signal is compared to the atmospheric pressure via the vent tube and compensated to the water temperature to produce an accurate level measurement. The benefit of an Oyster submersible pressure transducer is the ease of installation. Just strap the transmitter to a pipe and lower to the desired zero (0) level. That’s it. No calibration required! Connect the 2-wire loop powered 4-20mA output and you’re done!
