How to choose an ultrasonic water flow meter?
The correct selection of the ultrasonic flow meter can ensure the better use of the ultrasonic water flow meter. What kind of ultrasonic flowmeter to choose should be determined according to the physical and chemical properties of the fluid medium to be measured, so that the diameter, flow range, lining material, electrode material and output current of the ultrasonic flowmeter can be adapted to the nature of the fluid being measured. And flow measurement requirements.
1. Precise functional inspection
Accuracy level and function Choose the instrument accuracy level according to the measurement requirements and use occasions, so as to be economical and cost-effective. For example, for trade settlement, product handover and energy metering, you should choose a higher accuracy level, such as 1.0, 0.5, or higher; for process control, choose different accuracy levels according to the control requirements; some are only It is to check the process flow and do not need to do precise control and measurement. You can choose a lower accuracy level, such as 1.5, 2.5, or even 4.0. At this time, you can choose a cheap plug-in ultrasonic flowmeter.
2. Measurable medium
Measuring medium flow rate, instrument range and caliber When measuring general medium, the full-scale flow of ultrasonic flowmeter can be selected in the range of measuring medium flow rate 0.5-12m/s, and the range is relatively wide. The instrument specification (caliber) selected is not necessarily the same as the process pipeline. It should be determined whether the measurement flow range is within the flow rate range, that is, when the flow rate of the pipeline is too low to meet the requirements of the flow meter or when the measurement accuracy cannot be guaranteed at this flow rate, It is necessary to reduce the diameter of the meter to increase the flow velocity in the pipe and obtain satisfactory measurement results.
