1.4. Principle Of Measurement
Our ultrasonic flow meter is designed to measure the fluid velocity of liquid within a
closed conduit. The transducers are a non-contacting, clamp-on type, which will
provide benefits of non- fouling operation and easy installation.
The transit time flow meter utilizes two transducers that function as both ultrasonic
transmitters and receivers. The transducers are clamped on the outside of a closed
pipe at a specific distance from each other. The transducers can be mounted in
V-method where the sound transverses the pipe twice, or W-method where the
sound transverses the pipe four times, or in Z-method where the transducers are
mounted on opposite sides of the pipe and the sound crosses the pipe once. This
selection of the mounting method depends on pipe and liquid characteristics. The
flow meter operates by alternately transmitting and receiving a frequency
modulated burst of sound energy between the two transducers and measuring the
transit time that it takes for sound to travel between the two transducers. The
difference in the transit time measured is directly and exactly related to the velocity
of the liquid in the pipe.

θ is the include angle to the flow direction
M is the travel times of the ultrasonic beam
D is the pipe diameter
T up is the time for the beam from upstream transducer to the downstream one
T down is the time for the beam from downstream transducer to the upstream
one
ΔT=Tup –Tdown
1.5. Typical Application
Portable/handheld ultrasonic flowmeter is used to measure the flow and heat of
various single uniform liquids that can conduct ultrasonic waves.
Portable/handheld ultrasonic flowmeter adopts non-contact measurement method,
with large measurement range, no moving mechanical parts, and is not affected by
system pressure and harsh environment. It has been widely applied to water, pure
water, sea water, sewage, chemical liquids, rivers In the measurement of water,
fuel oil and other fluids. The upper limit temperature of the standard sensor is
110ºC. Please contact the manufacturer or supplier if the temperature exceeds this
temperature.
Portable/handheld ultrasonic energy meters are widely used in the measurement of
system energy consumption in refrigeration, heating, heat exchangers, freezers,
boilers and other industries.
