An electromagnetic flowmeter consists of a sensor and a converter. How to choose the protection rating for an electromagnetic flowmeter? The editor of electromagnetic flowmeters is here to tell you. Electromagnetic flowmeters are widely used in industries such as petroleum, chemicals, metallurgy, light textiles, papermaking, environmental protection, and food processing, as well as in areas like municipal management, water conservancy construction, and river dredging, for flow measurement. Under normal circumstances, the protection rating of integrated electromagnetic flowmeters is IP65. According to standard GB4208-84 and the International Electrotechnical Commission standard IEC529-76 regarding the protection ratings for the enclosures of electrical and electronic products: 1. IP65: This rating indicates protection against water spray; the sensor enclosure of an electromagnetic flowmeter can withstand water sprayed at it from any direction using a faucet, with a water pressure of 30 Kpa, a flow rate of 12.5 L/S, and a distance of 3 meters. 2. IP67: The sensor of the electromagnetic flowmeter can be immersed in water for a short period of time. 3. IP68: This rating indicates a submersible design – the device can operate in water or underground under certain pressures over extended periods of time. In such cases, the sensor and the display unit of the electromagnetic flowmeter are separated, resulting in a split-type electromagnetic flowmeter; it is important to pay attention to the protection rating requirements of the electromagnetic flowmeter. Under normal circumstances, the protection rating should be selected based on actual conditions. For electromagnetic flowmeter sensors that need to be installed below the ground level and are frequently exposed to water, IP68 should be chosen; whereas for sensors installed above the ground level, IP65 or IP67 is appropriate. Under no circumstances should the display area of an electromagnetic flowmeter be exposed to water or flooded, as this can cause damage to the flowmeter.
