Control Electronics model CPS-460DH Ultrasonic Doppler Flowmeter is a non-contacting, non-intrusive system that continuously monitors the flow in full pipes with at least 70 ppm suspended solids or air bubbles, indicating flow rate, totalized flow and many other variables. The system has 2 independent 4-20 mA analog outputs, 4 control relays and 1 sampler pulse relay, all programmable. The sensors may be mounted on any pipe size from 1.0” to 50”. A 200 day time stamped data logging provides 24 hour summary of flow rate, total flow for day, number of pump cycles with run time and more.
The US460DH Sensor is a dual-head arrangement with 25 feet of coaxial cable. The PVC sensors are easily mounted to the outside of the pipe using the supplied Silicone grease ( coupling paste ) and user supplied stainless steel hose clamp.
Typical sensor mounting
The Model CPS-460R allows for remote monitoring of up to 1000 feet using an inexpensive two twisted pair shielded interconnect cable. The Ultrasonic transmit and receiver card is located at the measuring site in a NEMA 4X enclosure.

EVENT list time stamped ( view by down load only ) using
any standard communication software
* Flow velocities of approximately less than 1.0 FPS (±0.5) not
recommended ( This is transition from turbulent to laminar flow -
calibrations different )
** Application dependent - velocity / pipe may necessitate higher ppm
*** Received signal is application dependent. Field / application conditions
may affect apparent accuracy
