1. Selection of Clamp on Electromagnetic Flow Meter

The selection of clamp on electromagnetic flow meter needs to be comprehensively considered from three aspects: measuring medium, temperature and pressure range, and measuring range. Specifically, the preliminary selection of measuring medium should be based on the characteristics of the measured medium on site, and the type of medium (such as liquid, gas, or mixed medium) and whether there are corrosive components or other special substances should be confirmed. For example, if the medium has strong corrosiveness, an electromagnetic flowmeter with corrosion-resistant lining (such as polytetrafluoroethylene, ceramics, etc.) should be selected; If the medium contains solid particles, the wear resistance of the lining needs to be evaluated. The temperature and pressure range of the modular clamping electromagnetic flowmeter should be clearly defined and installed on the pipeline, and the temperature and pressure range of the medium inside the pipeline should be confirmed in advance. Temperature range: Different lining materials have different temperature tolerances (for example, rubber lining is usually suitable for -20 ℃~80 ℃, while PTFE lining can withstand -20 ℃~180 ℃), and should be selected according to actual working conditions. Pressure range: It is necessary to ensure that the rated pressure of the flowmeter is higher than the maximum pressure inside the pipeline, in order to avoid equipment damage or measurement errors caused by excessive pressure. According to the combination range of temperature and pressure, select the electromagnetic flow key residual meter that matches the parameters to ensure its stable operation under working conditions. To dete

rmine the measurement range, it is necessary to specify the flow range of the medium in the pipeline (such as minimum flow, maximum flow, and common flow), in order to verify whether the range of the electromagnetic flowmeter matches. If the flow rate is too low, it may lead to weak signals and a decrease in measurement accuracy; If the flow rate is too high, it may exceed the upper limit of the flow meter range and damage the equipment. It is necessary to choose a flow meter with a range that covers the actual working conditions and leaves a certain margin. For example, if the actual maximum flow rate is 10m ³/h, a model with a range of 0-15m ³/h can be selected. Attention: When selecting, it is necessary to comprehensively evaluate the above three factors to avoid single parameter matching and ignoring other conditions. For example, focusing only on range matching without considering temperature and pressure may result in equipment failure under high temperature and pressure; Or focusing only on the corrosiveness of the medium without checking the flow range may cause measurement errors. If there are any doubts about the selection, you can further communicate and confirm with professional manufacturers (such as Daquan Flow).

2. What should be considered when choosing a gas flowmeter

When choosing a gas flowmeter, the following aspects should be considered:

1. The type of gas flowmeter should be selected based on actual working conditions and the characteristics of the measured medium.

. Different types of flow meters are suitable for different fluid characteristics, flow rate ranges, pressure levels, and temperature ranges. Therefore, when selecting, it is necessary to clarify the properties of
