　　4、 Attention:

　　When placing an order, the separation distance between the sensor and the converter should be specified, generally not exceeding 100m, and the converter should be wall mounted.

　　1. The accuracy level and function of the instrument are selected based on measurement requirements and usage scenarios to achieve cost-effectiveness. For example, in situations such as trade settlement, product handover, and energy measurement, higher accuracy levels such as 1.0, 0.5, or higher should be selected; For process control applications, choose different accuracy levels according to control requirements;

　　In some cases where only the process flow rate needs to be detected without precise control and measurement, a slightly lower accuracy level, such as 1.5, 2.5, or even 4.0, can be selected. In this case, a low-cost plug-in electromagnetic flowmeter can be used.

　　2. When measuring the flow rate, range, and diameter of a medium, the full flow rate of an electromagnetic flowmeter can be selected within the range of 0.5-12m/s for measuring the flow rate of the medium, which is relatively wide.

　　The selection of electromagnetic flowmeter specifications (diameter) may not necessarily be the same as the process pipeline, and should be determined based on whether the measured flow range is within the flow rate range. That is, when the pipeline flow rate is too low to meet the requirements of the flow instrument or the measurement accuracy cannot be guaranteed at this flow rate, the instrument diameter needs to be reduced in order to increase the flow rate inside the pipeline and obtain satisfactory measurement results.

　　3. Installation should avoid ferromagnetic objects and equipment with strong electromagnetic fields as much as possible to prevent the magnetic field from affecting the working magnetic field and flow signal of the sewage flowmeter.

　　4. It should be installed in a dry and ventilated place as much as possible, avoiding direct sunlight and rain. The ambient temperature should be between -20 and+60 ℃, and the relative humidity should be less than 85%.
