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
