Two important criteria for choosing a turbine flow meter
The selection of a suitable turbine flowmeter is very important for use, the selection of turbine flowmeter should be determined according to the physical and chemical properties of the measured body medium, and to make the flowmeter diameter, flow range, lining materials, electrode materials and output current, etc., can adapt to the nature of the measured body and flow measurement requirements. Here’s a closer look:
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 selected higher; For process control, select different precision levels according to control requirements; Some are just to detect the process flow, do not need to do precise control and measurement occasions, you can choose a slightly lower accuracy level, then you can choose a low-cost plug-in turbine flowmeter.
2. Measurable media:
When measuring medium flow rate, instrument range and diameter, the full degree flow rate of the liquid turbine flowmeter can be selected in the range of measuring medium flow rate 0.5-12m /s, and the range is relatively wide. The selection of instrument specifications (caliber) is not necessarily the same as the process pipeline, should be determined according to whether the measured flow range is within 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 improve the flow rate in the tube, and obtain satisfactory measurement results.
