It measures both clear water and cloudy liquids accurately!

ULTRASONIC LIQUID FLOW METER & SWITCH
PF/U/DFM/DFS Series
It measures both clear water and cloudy liquids accurately!
  • It can make measurement quickly and accurately from the outside of a pipe.
  • It can be attached directly to the existing pipe regardless of materials (metal pipe, resin pipe, lining pipe, etc.).
  • The settings can be made easily according to instructions.
  • The instantaneous flow rate, flow velocity, and integral flow rate can be confirmed on the display.

operating principles

Ultrasonic waves are transmitted into a liquid alternately from the 2 sensors attached to the outside of the pipe, and difference between the propagation time of the ultrasonic wave in the upstream direction and the propagation time in the downstream direction is detected to obtain the flow velocity. Then, the flow rate is calculated by multiplying the cross section area of the pipe diameter. flow meter image
