Portable ultrasonic flow meter takes a state-of-the-art transit time measurement principle in digital signal processing. It is designed to work with the clamp on transducer, to provide accurate measurement of liquid flow within a closed pipe line.There is not any mechanical parts to be inserted into the pipe wall Or to protrude into the flow system. It just takes a few minutes to install, and it is not necessary to shut down the flow or drain the system.
