The correct selection of the target flowmeter can ensure the better use of the target flowmeter. What kind of target flowmeter should be selected according to the physical and chemical properties of the fluid medium to be measured?
The diameter, flow range, and output mode of the target flowmeter can be adapted to the nature of the fluid being measured and flow measurement requirements.
- Precise function inspection
Accuracy grade and function Select the instrument accuracy grade according to the measurement requirements and use occasions, so as to be economical. 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 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 target flowmeter.
- Measurable medium
Measuring medium flow rate, instrument range, and caliber When measuring general medium, the full-scale flow of the target flowmeter can be selected within the range of 0.1-12m/s to measure the medium flow rate, and the range is relatively wide. The specification (caliber) of the selected instrument is not necessarily the same as that of the processing 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.
