Monitoring Our Precious Resource

Description


Control Electronics model ERS-560 Ultrasonic Level Monitor is an accurate, non-contacting liquid level measuring system.  The unit monitors liquid level in almost any standard tank configuration using sophisticated ultrasonic ECHO ranging techniques. The PVC sensor is supported above the liquid level providing accurate, instantaneous levels along with calculated stored gallons, data logging, two 4-420 mA. analog outputs and 5 programmable control relays with independent ON/OFF settings for differential control.


The system features easy programming and set up. The sensor operates with a low pulsed voltage making it environmentally non-hazoardous. Control pumps with lead/lag alternate function.

The US70TC Sensor uses an inexpensive twisted pair shielded cable, 700 feet maximum.  The sensor uses a lower pulse voltage than most other manufacturers.  The sensor is easily mounted using PVC components and due to the low operating voltage,  is considered non-hazardous, eliminating potential arcing of a faulty cable or connection.

ERS-560 / 560DX Ultrasonic Level Monitor

The US70TC Sensor with built-in temperature probe, uses an inexpensive twisted pair shielded cable. No complicated multi-pair cable or expensive coaxial cable.
