How to correctly select the integrated electromagnetic flowmeter?

Intelligent electromagnetic flowmeter consists of two parts: sensor and converter. It works based on Faraday's law of electromagnetic induction and is used to measure the volume flow of conductive liquids with a conductivity greater than 5 μS/cm. It is an inductive instrument that measures the volume flow of conductive media. In addition to measuring the volume flow of general conductive liquids, it can also be used to measure the volume flow of highly corrosive liquids such as strong acids and alkalis, and uniform liquid-solid two-phase suspension liquids such as mud, pulp, and paper pulp.

1. Selection of caliber and range: The transmitter caliber is usually the same as the pipeline system. If the piping system is to be designed, the diameter can be selected based on the flow range and flow rate. The range of the transmitter can be selected based on two principles: first, the full scale of the instrument is greater than the expected maximum flow value; second, the normal flow is greater than 50% of the full scale of the instrument to ensure a certain measurement accuracy.

2. Selection of temperature and pressure There are certain limitations on the fluid pressure and temperature that the "Xiyi" brand electromagnetic flowmeter can measure. When selected, the operating pressure must be lower than the specified working pressure of the flow meter. If you have special requirements for the transmitter's pressure resistance, you can negotiate with the manufacturer for details. The operating temperature of the electromagnetic flowmeter depends on the lining material used.

3. Selection of lining material and electrode material. The lining material and electrode material of the transmitter must be selected correctly according to the physical and chemical properties of the medium, otherwise the instrument will be damaged due to the lining and electrode. It will be damaged quickly due to corrosion, and leakage of highly corrosive media can easily cause accidents. The above are the principles for selecting electromagnetic flowmeters.

During the selection process, we clearly understand the medium, pressure, temperature, flow rate, and caliber measured by the electromagnetic flowmeter. The electrode material selection is customized according to customer requirements. The standard configuration is 316L. For sewage measurement or corrosive media, please specify in advance.
