Ultrasonic flowmeter is a more mature product in non-contact flowmeter. Ultrasonic measurement principle also brings it a variety of other flowmeter difficult to obtain the advantages, in the accuracy and resolution of the same premise, the non-contact flowmeter has easy installation and use, large range, bidirectional measurement and other advantages, then let us specifically understand the advantages of ultrasonic flowmeter.
1. Easy installation
The ultrasonic flowmeter supports the installation of the external clamp, without changing the original pipeline, the installation cost is low, and there is no need to design the corresponding pipeline for the installation of measuring instruments in the pipeline design. The installation process does not need to affect the normal use of the pipeline.
2. Not affected by the nature of the measured medium
Contact measuring instruments need to consider the loss caused by various reactions between the sensor part and the measured medium, such as rust, corrosion, hanging material, etc. Moreover, the non-contact measurement of the ultrasonic flowmeter avoids the influence on the flow rate of the pipe section under test, and the flow loss is small.
3. Large range
Since the ultrasonic transmission speed in the liquid is usually about 1500m/s, the ultrasonic speed is much higher than the measured flow speed, which determines the high measurement upper limit. Because the non-contact type does not require the measured medium to push the mechanical parts, the measurement limit is low and the measurement accuracy is the same for low flow rates.
4. Bidirectional measurement
Mechanical flowmeters either cannot respond to the reverse flow due to their structure, or can measure the reverse flow but cannot show the flow direction in the signal output. Ultrasonic flowmeter because of the use of time difference method and other measurement methods, the positive and negative direction of the flow can be correctly measured.
5. Easy maintenance
Also due to the advantages of external installation, there is no need to empty the liquid in the pipeline during equipment maintenance and maintenance, which has little impact on production. The maintenance interval is longer because it does not involve the accumulation of impurities, sensor loss and other issues.
In view of the above characteristics, the installation characteristics of the ultrasonic flowmeter bring a lot of convenience to the use. The application range is larger, the maintenance cost is lower, when there is a flow measurement demand, ultrasonic flowmeter will be a good choice.
