External mounted clamp type ultrasonic flowmeter

External mounted clamp type ultrasonic flowmeterIt is a measuring device installed on pipelines for non-invasive purposesMeasure the flow rate of a fluid in a standardized manner. It emits ultrasonic pulses and is received by a receiver after passing through the fluidCollect and then calculate the flow rate and flow rate. The advantage of this flowmeter is that it does not generate pressure lossShutdown installation is required, and accurate measurements can be taken for different fluids.
