When to choose a plug-in ultrasonic flowmeter

1) When the pipe diameter is large;
2) When there is a tight lining;
3) When the scale in the pipe is serious;
4) When the pipe is a bad conductor of ultrasonic waves (such as cast iron pipe, cement pipe, etc.);
5) When the external clamped ultrasonic sensor does not reach the required signal strength or the measurement is unstable
6) When the measuring part of the measured tube is in a state of water for a long time
