VOLKE/Volke FEV ultrasonic flow meter

FEV external clamp-on ultrasonic flowmeter is widely used, universal and economical, external clamp-on, time-difference ultrasonic flowmeter. It has a very simple installation method, no need to break the pipe and no need to stop water, allowing customers to easily achieve flexible pipe flow measurement. Can be equipped with permanently installed fixtures that require no routine maintenance and provide reliable, drift-free measurements over the term. It adopts advanced digital correlation technology and intelligent adaptive acoustic wave technology to make the measurement stability more outst; at the same time, it uses patented acoustic focusing technology to significantly the signal reception and quality of the product during continuous measurement.

Features of FEV clamp-on ultrasonic flowmeter:

1. High precision, fully intelligent menu operation. 2. Online installation under pressure. 3. Positive and negative flow measurement, cumulative flow. 4. Using the time difference principle, the accuracy can be as high as 0.5%. 5. Fast response, stable and reliable, and strong anti-interference ability. 6. There are no mechanical parts in the measuring pipe diameter, so it is easy to maintain and has a service life. 7. No pressure loss and flow loss.
