PCE-VUS ultrasonic flow transmitter |
||||||||||||||||||
|
The PCE-VUS ultrasonic flow transmitter is a non-contact measuring sensor. This device is the ideal flow sensor when both duration and resistance are crucial. It allows a precise detection of flow without counting moving pieces. The PCE-VUS ultrasonic flow transmitter is the essential gauge while measuring moving parts as for example winged wheels. The liquid flows through a straight stainless steel tube isolated from any external element. The ultrasonic transmitter is placed outside the pipe and it has no contact with the environment. The measuring principle of the PCE-VUS ultrasonic flow transmitter is based on the ultrasonic transit time. There are two ultrasonic devices located in the external measurement tube. Both transducers are used as transmitter and receiver, sending an ultrasonic signal in the current direction and then in the opposite way. The difference between both ultrasonic speeds is proportional to the main flow velocity. If you have any question on the ultrasonic flow transmitter, see the technical data below or contact us: +44 ( 0 ) 2380 98703 0. Our technicians and engineers will advise you on this ultrasonic flow transmitter or any other product our regulation and control systems, meters or scales of PCE Instruments. |

- Without any moving part - Only one element which makes contact but is chemically resistant (stainless steel) - 4 ... 20 mA output - Shock resistant - Alarm output |
- Quick response - Ideal for non-conducting liquids, for instance distilled water. - With frequency output - No mechanical wear - Independent to the input and output route and the installation situation |
