Ultrasonic Flow Meter | Manas Microsystems is India’s one of the top Ultrasonic Flow Meter manufacturers and suppliers. A comprehensive range of ultrasonic flow meters is available from us, including Bulk Type Ultrasonic Flow Meters, Clamp-on Type Ultrasonic Flow Meters, and Insertion Ultrasonic Flow Meters, Portable Ultrasonic Water Flow Meter and Handheld Ultrasonic Water Flow Meter. For the volumetric metering of water, ultrasonic flow meters have been used in businesses and markets for a long time.

Many engineers are interested to know how does an ultrasonic flow meter work.

There are two types of Ultrasonic Flow Meters. One works on the Transit Time or Time of Flight principle. The second one works on the Doppler Effect principle.

The transit time meter is used for clear liquids or liquids having very low levels of undissolved solids.

When the ultrasound wave passes through the liquid the component of liquid velocity is added to ultrasound velocity. By careful measurement of the Time required by the sound wave to reach the other end of the diameter, one can calculate accurately the water velocity. By knowing the velocity the volumetric flow rate can be calculated.

Doppler meter is suitable for liquids having a high level of undissolved solid contaminations. When the sound wave gets reflected from any particle in the flow its frequency changes and observing the change in frequency the velocity of the particle can be calculated and in turn the volumetric flow.
