Insertion Ultrasonic Flow Meter

Manas have now introduced a new Insertion Type Ultrasonic Flow Meter. Insertion Type Ultrasonic Flow Meter works on the Transit Time or Time of Flight Principle. The flow meter unit utilizes two transducers that functions as both Ultrasonic transmitter and receiver. The transducers are either clamped on or inserted to the outside surface of the closed pipes. The transit time flow meter measures the time it takes for an ultrasonic signal transmitted from one transducer to cross the pipe and be received by second transducer. The flow is then measured by comparing the upstream & downstream time of Ultrasonic signal. With no flow through the pipe the transit time would be equal in both directions.

Principle Of Operation:
For measuring the Flow of the medium, two ultrasonic pulses are sent through the medium, one in the flow direction and another in the opposite direction. The transit time of the two pulses are then measured. The transit time difference At between these two pulses gives the average flow velocity on the propagation path of the Ultrasonic Signals. This can be used to obtain the average of flow velocity on the cross section of the pipe, which is proportional to the volumetric flow.

Features :

• Sizes available for 1" to 24" [DN25 -DN600]
• The meter Contains No Moving parts and Fast response to the flow transits.
• Highly Accurate and Reliable.
• Isolated 4-20 mA output Proportional to flow Rate. 
• No need to cut the pipe or stop water, easy installation
  • Applicable Line Size: DN50 To DN600
