Manas Microsystems is India’s leading Ultrasonic Flow Meter manufacturer and supplier company. We have been recognized as one of India’s Top Flow Meter manufacturers recently. 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 in knowing how an ultrasonic flow meter works.
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.
Manas makes Transit Time-based Ultrasonic Flow Meters.
The transit time meter is used for clear liquids or liquids having very low levels of undissolved solids.
Features
Advanced DSP technology and the multi-pulse Transducer technology
Special Type Insertion Transducers allow solids to pass through the pipe within the effect on the meter. Y-strainers or filtering devices are not needed.
Digital cross-correlation technology
Provides easy and low-cost installation on the outside of the existing piping system without cutting the pipe section.
Clear, user-friendly, and convenient to use
A pair of sensors can satisfy different materials and wide pipe diameters.
2 lines of display can display total flow, flow rate, velocity, and meter run status. Parallel operation of positive, negative, and net flow totalize with scale factor and 7 digit display, while the output of totalize pulse and frequency output are transmitted via the open collector.
U.S., British and Metric measurement units are available

2. PRINCIPLE OF OPERATION
For measuring the ow of the medium, two ultrasonic pulses
are sent through the medium, one in the ow direction and
another in the opposite direction.
The transit time of the two pluses are then measured. The
transit time difference at between these two pluses gives the
average ow velocity on the propagation path of the Ultrasonic
Signals. This can be used to obtain the average of ow velocity
on the cross section of the pipe, which is proportional to the
volumetric ow.

INTRODUCTION
Manas Microsystems is one of India’s top Ultrasonic Flow
Meter manufactures and suppliers. A comprehensive range
of Ultrasonic Flow Meters is available from Manas, including
Clamp-on Type Ultrasonic Flow Meters, and Insertion
Ultrasonic Flow Meters, Portable Ultrasonic Water Flow
Meter and Handheld Ultrasonic Water Flow Meter. These
meters work on transit time principle.
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 ow rate can be calculated.
For the volumetric metering of water, ultrasonic ow
meters have been used in businesses and markets for a
long time. The transit time meter is used for clear liquids
of liquids having very low levels of undissolved solids.
FEATURES
Ÿ Sizes available for 2” to 80” (DN50 -DN2000)
Ÿ The meter contains no moving parts and fast response to
ow transits
Ÿ Highly accurate and reliable
Ÿ Isolated 4-20 mA output proportional to flow rate
Ÿ No need to cut the pipe or stop water, easy installation
