1. What is the wiring diagram of the flowmeter? How is the flowmeter wired? The wiring method of the flowmeter may vary depending on the type and brand. Here are two common wiring methods for flow meters for your reference.
1. Wiring method for split type flow meters: As shown in the above figure, the sensor and accumulator of the split type flow meter are installed separately and connected through signal cables. When wiring, it is necessary to connect the output signal of the sensor to the input terminal of the integrator. Generally speaking, the wiring method of a split type flowmeter is relatively simple. Simply connect the corresponding signal line to the integrator.
2. Wiring method of an integral flowmeter: As shown in the diagram, the integral flowmeter integrates the sensor and integrator together without the need for signal cables.
. When wiring, it is necessary to connect the output signal of the sensors dead end finger to the input terminal of the integrator. The wiring method of the integral flowmeter is relatively simple, just connect the corresponding signal line to the accumulator. It should be noted that different types of flow meters have different wiring methods, so it is necessary to carefully read the user manual of the flow meter before wiring to understand the correct wiring method. At the same time, safety should be taken into account during the wiring process to avoid contact with live parts or dangerous operations.

2. Installation Requirements for Electromagnetic Flow Meter

The installation of electromagnetic flow meters must meet the following requirements to ensure measurement accuracy and stable operation of the equipment:

1. The installation position sh

ould be selected vertically or at the lowest point. Priority should be given to installing at the lowest point or vertical section of the pipeline to ensure that the measuring tube is always filled with liquid (full tube state).

. When installed vertically, the direction of water flow should be from bottom to top to avoid flow fluctuations caused by top-down. Avoid interfering with the environment and stay away from strong magnetic field equipment (such as motors and transformers), strong seismic sources, and highly corrosive places. If the process does not allow flow interruption, it is necessary to add a cut-off and flushing cherry valve and a bypass pipeline for maintenance.

Secondly, the straight pipe section requires a length of 5D in the front and 3D in the back (D is the pipe diameter): a straight pipe section with a diameter of 5 times the pipe diameter is required upstream of the sensor, and a straight pipe section with a diameter of 3 times the pipe diameter is required downstream.

. In some scenarios, the upstream straight pipe section can be relaxed to 5D~10D, but it is necessary to ensure fluid stability. Coaxial and full tube requirements: The measuring tube and the process pipeline must be coaxial to avoid tilting or eccentricity. It must run at full capacity, otherwise it will cause measurement values to jump or fail.

III. Protection Level and Selection Protection Level Selection The integrated electromagnetic flowmeter has a protection level of IP65 and is suitable for dry environments.

. The protection level of the split type sensor is IP68, suitable for harsh environments such as underground manholes and humidity. When measuring corrosive liquids with matching medium properties,
