Small Pipe Ultrasonic Flow Meter For PVC Pipe With Pure Water
I INTRODUCTION
ML-F8 is very unique in its structural design. It uses a circular
magnetic steel to achieve automatic connection during
installation.It takes only 2-3 minutes to complete the whole
process from installation to measurement. It also adopts the
current popular OLED display, which makes it easy to read in low
light conditions.
ML-F8 is widely used in the production process for flow measurement
and monitoring. The application of the product continuously and
effectively controls the flow of the fluid, so as to improve the
yield of the product and even save the input of the personnel,
bringing benefits to the production enterprise.
- Clamp on type, no need to cut the pipe or do any other changes.
- No professional product knowledge required, installation and
measurement can be done based on the guide.
- No moving parts or pressure changes involved, installation can be
done without stop provide.

IV. WORKING PRINCIPLES
Ultrasonic flow meters use sound waves at a frequency beyond the
range of hearing (typically 0.5, 1, or 4 MHz). This ultrasound
signal is sent into a stream of flowing liquid by using wetted
(insertion) transducers that make direct contact with the liquid or
external (clamp-on) transducers that send the ultrasound through
the pipe wall. Clamp-on ultrasonic flow meters allow users to
measure the volumetric flow rate of a fluid in a pipe without
having to penetrate the pipe which decreases installation and
maintenance costs.
A typical transit-time ultrasonic liquid flow meter utilizes two
ultrasonic transducers that function as both ultrasonic transmitter
and receiver. The ultrasonic flow meter operates by alternately
transmitting and receiving a burst of ultrasound between the two
transducers by measuring the transit time that it takes for sound
to travel between the two transducers in both directions. The
difference in the transit time (∆ time) measured is directly
proportional to the velocity of the liquid in the pipe.
Why choose ultrasonic?
Ease-of-Installation: The largest benefit of any “clamp-on” transit-time flow meter is
the ease-of-installation. While still requiring sections of
straight pipe upstream of the measurement location, the process
does not require shutting the system down to install, making
maintenance and upkeep of transit-time meters much more attractive.
Low maintenance: There are no blades to wear out or bearings to replace as in
turbine meters, nor are there electrodes that can foul over time as
in magnetic flow meters.
