PCE-VUS
ultrasonic flow meter |
||||||||||||||||||
|
The PCE-VUS ultrasonic flow meter is a non-contact measuring sensor. The PCE-VUS ultrasonic flow meter is the ideal flow sensor when both duration and resistance are very important. The PCE-VUS ultrasonic flow meter allows for the accurate detection of flow without counting moving pieces. The PCE-VUS ultrasonic flow meter is an essential device for measuring moving parts such as for instance winged wheels. The liquid flows through a straight stainless steel tube isolated from any external element. The ultrasonic transducer is located outside the pipe and doesn't have any contact with the environment. The measuring principle of the PCE-VUS ultrasonic flow meter 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 reverse. The difference between the two ultrasonic velocities is proportional to the mean flow velocity. If you can't find the ultrasonic flow meter you are looking for, click here. |
