Solve the electromagnetic valve water meter

Look at the working voltage of the solenoid valve. It should be marked on the solenoid valve. Just add a voltage directly, and the water can be discharged. Solenoid valves include DC 5V, DC 12V, DC 24V, DC 48V, AC 1 10V, AC 220V, pulse solenoid valves and so on. If this solenoid valve is AC 220V, just connect the wire on the solenoid valve to 220V directly.

Electromagnetic water meter refers to the electromagnetic flowmeter with built-in battery power supply, which has the same principle as the electromagnetic flowmeter, but does not need external power supply. At present, the world-famous electromagnetic water meters mainly include MGG series open-flow meters. Due to technical reasons, the aperture of the current electromagnetic water meter is generally less than 600 mm.

Water meter installation

1, select the correct water meter caliber.

2. Install horizontally, with the surface facing upwards, and the direction of the arrow on the watch case is consistent with the direction of water flow. The installation position should avoid exposure to sunlight, immersion, freezing and pollution, which is convenient for disassembly and meter reading. Before installing the water meter, the newly installed pipeline must clean up sand, gravel, hemp and other sundries to avoid water meter failure.

3. Valves should be installed upstream and downstream of the water meter, and all valves should be opened when using.

4. Necessary straight pipe sections or their equivalent rectifiers shall be installed upstream and downstream of the water meter, with the length of the upstream straight pipe section not less than 10D and the length of the downstream straight pipe section not less than 5D(D is the nominal caliber of the water meter). For the vortex phenomenon caused by elbow or centrifugal pump, a rectifier must be installed in front of the straight pipe section.
