The use of ultrasonic flowmeter should pay attention to several considerations
The correct selection of ultrasonic flowmeter can ensure the better use of ultrasonic flowmeter. What kind of ultrasonic flowmeter should be selected should be determined according to the physical and chemical properties of the measured flow medium. Today, flowmeter manufacturers tell you what to pay attention to before choosing ultrasonic flowmeter
1, precision functional inspection
Accuracy level and function According to the measurement requirements and the use of the instrument accuracy level, to achieve economic. For example, for trade settlement, product handover and energy measurement, the accuracy level should be higher, such as 1.0, 0.5, or higher; For process control, different precision levels are selected according to control requirements; Some just detect the process flow, do not need to do precise control and measurement occasions, you can choose a slightly lower accuracy level.
2, measurable media
When measuring the medium flow rate, instrument range and diameter, the full degree flow rate of the ultrasonic flowmeter can be selected in the range of measuring the medium flow rate of 0.5-12m /s, and the range is relatively wide. The selection of instrument specifications (caliber) is not the same as the process pipeline, should be determined according to the measurement flow range, in the flow rate range, that is, when the pipeline flow rate is low, can not meet the requirements of the flow meter or the measurement accuracy cannot be guaranteed at this flow rate, it is necessary to reduce the diameter of the instrument, so as to increase the flow rate in the tube, to obtain satisfactory measurement results.
There are other suggestions for the selection of ultrasonic flowmeters that you can discuss with the Aister meter staff online at any time.
