The correct selection of the turbine flowmeter can ensure the better use of the turbine flowmeter. What kind of turbine flowmeter should be selected according to the physical and chemical properties of the fluid medium to be measured? The diameter, flow range, lining material, electrode material and output current of the turbine flowmeter can all be adapted to the nature of the fluid being measured. And flow measurement requirements.
1. 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 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. In this case, you can choose a cheap plug-in turbine flowmeter.
2. Measurable medium
Measuring medium flow rate, instrument range and caliber When measuring general medium, the full-scale flow of the turbine flowmeter can be selected within the range of measuring medium flow rate 0.5-12m/s, and the range is relatively wide. The selected instrument specification (caliber) is not necessarily the same as that of 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 low and cannot 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 caliber of the instrument so that the flow velocity in the high-level pipe can be satisfactorily measured.
