Application of Ultrasonic Flow Sensor

Ultrasonic flow sensor is suitable for continuously measuring the flow and heat of most clean and uniform liquids without large concentration of suspended particles or gases in industrial environment. It is widely used in factory sewage discharge monitoring, cementing mud flow measurement, oilfield oily sewage flow measurement, oil well water injection flow measurement, tap water flow measurement, industrial circulating water flow measurement, production process water consumption measurement, beneficiation slurry flow measurement, beneficiation slurry flow measurement, sodium aluminate and other process flow measurement and control, cooling circulating water flow measurement, generator coil cooling water flow measurement Milk flow measurement.

Main features of ultrasonic flow sensor

  1. The transmitting crystal of the ultrasonic flow sensor is in direct contact with the measured liquid, which improves the measurement accuracy and the operation stability of the machine;
  2. It solves the problems of weak signal and abnormal measurement when using external bound sensor due to scaling or serious corrosion on the inner wall of the pipeline; It can also be installed on the cement pipeline (the actual outer diameter of the pipeline must be known, and the pipe hoop can be customized from the manufacturer);
  3. It solves the problems that the coupling agent is dry due to the long-term use of the external clip sensor, which affects the normal transmission and operation of the ultrasonic signal;
  4. The special opening tool used can make the figareth ultrasonic flow sensor installed under pressure without water supply, so as to ensure the normal and stable operation of production, and there is no need to cut off water for future maintenance;
  5. Compared with electromagnetic flowmeter, it is economical, reliable and accurate to use in large-diameter pipeline.

Attention for Flow Sensor

The production1. Large fluctuation of instantaneous flowmeter

① The signal strength fluctuates greatly; ② The measurement fluid itself fluctuates greatly;

Solution: adjust the position of the probe and rotate the evaporator to improve the signal strength (keep it above 3%) to ensure the stability of the signal strength. If the fluid itself fluctuates greatly, the position is not good. Re select the point to ensure the working conditions of the first 10d and the second 5D.

  1. Low signal of external clip ultrasonic flow sensor

The pipe diameter is too large, the pipe scaling is serious, or the installation method is wrong.

Solution: for excessive pipe diameter and serious scaling, it is recommended to use plug-in probe or choose “Z” installation mode.

  1. After the plug-in probe is used for a period of time, the signal decreases?

The probe may be offset or the scale on the probe surface may be thick.

Solution: readjust the position of the probe and clean the emitting surface of the probe.

What does customer say about FBELE Company


We cooperated with FBELE since 2018,what ever time I send massage to FBELE, I allways get their quickly reply even in middle ninght in BeiJing time, it seems we have no time difference with FBELE,It’s really amazing,it really very good service!


We know FBELE in June 2021 ,we are new client,

When I first bought FBELE products, I was worried about the quality, but after receiving the first batch of trial order goods, my doubts were dispelled. FBELE product quality is very good! We will place big order this year, thanks for FBELE!

Genaral Questions About Flow Sensor

What kinds of flow sensors does FBELE have?

Flow sensors can be divided into water flow sensors, plug-in flow sensors, vane air flow sensors, vortex flow sensors, Karman vortex air flow sensors, hot wire air flow sensors and so on.

What are the frequency of normal flow sensors?

Generally speaking, the user can reset the frequency range of the frequency signal and the range of the displayed instantaneous flow according to actual needs. The operating frequency range of the ordinary ultrasonic flowmeter itself is 80KHz-180KHz, and the center frequency is 120KHz.

What kinds of gas flow sensors are there?

Nowadays, there are many types of gas flow sensors, including throttle type, volumetric type, vortex type, electromagnetic type, thermal type, ultrasonic type, etc.

What is the features of flow sensors?

Small size, light weight, intuitive and clear display readings.High reliability, not affected by external power supply, anti-lightning.

What is the basic principle of flow sensor?

Different flow sensors work very differently. For example, some ultrasonic flow sensors are based on the Doppler method, which uses the reflection of the medium to the sound wave to change the frequency, thereby generating a frequency difference when the sound source and the medium receiving the sound wave move relative to each other; some are based on the running time method, that is, the speed of sound The superimposed medium flow rate, if the ultrasonic wave and the water flow direction are consistent, the running time is short, otherwise the running time is long
