When the ultrasonic flowmeter is installed, the signal strength of the ultrasonic sensor is large enough without any defects, but after a successful operation period, the signal of the ultrasonic sensor may become smaller and weaker. The causes of this problem may be as follows:
1. First, confirm whether the pipe is full filled by water flow.
2. If the pipe is too close to the wall, the ultrasonic sensor can be installed at an Angle to the pipe diameter, rather than the horizontal pipe diameter. Method Z should be used.
