Control Electronics model PDS-360 Ultrasonic Open-Channel Flowmeter is a highly accurate, non-contacting liquid flow measuring system. The unit monitors flow through any standard primary flow device using sophisticated ultrasonic ECHO ranging techniques. The sensor is supported above the liquid flow providing accurate, instantaneous flow rates with totalized volume flow. The system has 2 independent 4-20 mA analog outputs, 4 control relays and 1 sampler pulse relay, all programmable.
A 200 day time stamped data logging provides 24 hour summary of flow rate, min / max flow, total flow for day and more.
Note: Fiberglass enclosure shown has been updated to an ABS plastic enclosure.
The US70TC Sensor uses an inexpensive twisted pair shielded cable, 700 feet maximum. The sensor uses a lower pulsed 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.
The US70TC Sensor with built-in temperature probe, uses an inexpensive twisted pair shielded cable. No complicated multi-pair cable or expensive coaxial cable.
