What are the common fault factors? Fault phenomenon cause of issue Method of exclusion no signal The connection between the transducer and the host is disconnected reconnect Insufficient signal strength Power pollution Purification power supply Transducer position shift Re-adjust the transducer position Instantaneous flow is stable, but larger than the actual value The transducer wedge has failed Replace the transducer Large instantaneous flow fluctuations Fluid is disturbed, fluidity is unstable Replace transducer position Host damping coefficient setting size Increase the damping coefficient Instantaneous and cumulative flow inconsistency Host failure Replace the host Hydraulic Control Valve,Hydraulic System Flow Control Valve,Flow Control Valve Device,Automatic Hydraulic Control Valve Shuyang County Huji town Desheng hydraulic machinery factory , https://www.dshydraulic.com
What are the common fault factors of ultrasonic flowmeters?
The external clip type or tube type ultrasonic flow meter is a meter for measuring the liquid flow in a circular tube based on the principle of "speed difference method". It adopts advanced multi-pulse technology, signal digital processing technology and error correction technology, which makes the flow meter more adaptable to the industrial scene environment, and the measurement is more convenient, economical and accurate. The products have reached the advanced level at home and abroad and can be widely used in petroleum, chemical, metallurgy, electric power, water supply and drainage and other fields.
Ultrasonic flowmeters should be aware of the site prior to installation, including:
1. What is the distance from the host at the installation of the sensor;
2. Pipe material, pipe wall thickness and pipe diameter;
3. Year of the pipeline;
4. Type of fluid, whether it contains impurities, bubbles, and whether it is full;
5. Fluid temperature
6. Whether there is interference source at the installation site (such as frequency conversion, strong magnetic field, etc.);
7. The temperature of the four seasons at the host site;
8. Whether the power supply voltage used is stable;
9. Whether remote signals and types are required;
According to the site conditions provided above, the manufacturer can configure the site conditions and, if necessary, special models.
