Electromagnetic flowmeter sensor protection level

Many people confuse the protection level with the explosion-proof level. The protection level starts with IP and is usually used for liquid protection. The protection levels of electromagnetic flowmeters are divided into three, namely IP65, IP67, and IP68. Different The protection level applications are also different. Let us take a look at the differences between these three protection levels.

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.

Generally, it is integrated The protection level of the electromagnetic flowmeter is IP65. According to the national standard GB and the International Electrotechnical Commission standard IEC529-76, the standards for the protection level of electrical and electrical product shells are:

1. IP65: It is a water spray-proof type. The electromagnetic flowmeter sensor shell allows the faucet to pass through the electromagnetic field. The flow meter sensor sprays water on the sensor from any direction. The pressure of the water spray is 30Kpa, the water output is 12.5L/S, and the distance is 3 meters.

2. IP67: The electromagnetic flowmeter sensor can be immersed in water for a short period of time.

3. IP68: It is a submersible type. It is suitable for long-term work in water or underground under a certain pressure. At this time, the sensor and display part of the electromagnetic flowmeter are separated and a split electromagnetic flowmeter is used. However, The protection level requirements of electromagnetic flowmeters must be emphasized.
