JC****0S Wall Installed Ultrasonic Flow Meter
JC****0S 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.
BCST Ultrasonic Flow Meter Description
JC****0S 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, show as follows:
Where
θ is the include angle to the flow direction
M is the travel times of the ultrasonic beam
D is the pipe diameter
Tup is the time for the beam from upstream transducer to the
downstream one
Tdown is the time for the beam from downstream transducer to
the upstream one
ΔT=Tup Tdown
