Does the ultrasonic flowmeter need regular maintenance in use?

Ultrasonic flowmeter is a non-contact flowmeter, ultrasonic propagation in the fluid when its propagation speed is affected by the flow rate, by measuring the ultrasonic propagation speed in the fluid can detect the flow rate of the fluid and convert the flow rate. 

As a kind of instrument, giving maintenance is indispensable, only good maintenance, in order to measure more accurate, longer service life, maintenance is indispensable regular maintenance and calibration, as follows.

First, regular maintenance

Compared with other flowmeters, the maintenance amount of ultrasonic flowmeters is relatively small. For example, for the external transducer ultrasonic flowmeter, there is no water pressure loss after installation, no potential water leakage, just check regularly whether the transducer is loose, and whether the adhesive between the pipeline is good; The inserted ultrasonic flowmeter should regularly clean the impurities, scale and other water leakage deposited on the probe; Integrated ultrasonic flowmeter, to check whether the flange link between the flowmeter and the pipeline is good, and consider the impact of field temperature and humidity on its electronic components. Regular maintenance can ensure the long-term stable operation of the ultrasonic flowmeter. To implement it now, the maintenance of instruments is a long-term process, and other instruments are the same.

Second, check and verify in time

For users with a large number and a wide range of ultrasonic flowmeters installed on site, a portable ultrasonic flowmeter of the same type can be equipped for checking the situation of on-site instruments. First, adhere to one installation and one school, that is, check each newly installed ultrasonic flowmeter during installation and debugging to ensure good location selection, installation and measurement; The second is to use the portable ultrasonic flowmeter to check in time when the flow mutation occurs in the online operation of the ultrasonic flowmeter, to find out the cause of the flow mutation, to find out whether the instrument failure or the flow has indeed changed. In this way, the use of the flow meter can be monitored, and then the problem can be checked and then maintained.

Here’s a look at its advantages.

1, ultrasonic flowmeter is a non-contact measuring instrument, which can be used to measure the fluid flow and large pipe runoff that are not easy to contact and observe. It does not change the flow state of the fluid, does not produce pressure loss, and is easy to install.

2, can measure the flow of highly corrosive media and non-conductive media.

3, the ultrasonic flowmeter has a large measuring range, and the pipe diameter ranges from 20mm-5m.

4, ultrasonic flowmeter can measure a variety of liquid and sewage flow.

5, the volume flow measured by the ultrasonic flowmeter is not affected by the temperature, pressure, viscosity and density of the flow body and other thermal physical parameters. It can be made in both stationary and portable forms.
