2. The electromagnetic flowmeter is explosion-proof for use in places with explosive atmosphere. Due to the large excitation current energy, it is still mainly based on explosion-proof type. In recent years, intrinsic safety has emerged in foreign countries, that is, safety spark-type electromagnetic flowmeters, the excitation power is greatly reduced, and it can be made into an integrated type, all of which are installed in dangerous areas.
3. Electromagnetic flowmeters are used in electromagnetic flowmeters for industries such as medicine, food and biochemistry. They must meet the relevant hygiene requirements in terms of timing, easy disassembly and cleaning.
4, electromagnetic flowmeter anti-immersion type for the sensor installed under the ground, can withstand short-term water immersion.
5. The electromagnetic flowmeter submersible type is used to measure the flow when the open channel or the non-full pipe culvert is free flowing freely. The sensor is in the lower part of the open channel intercepting baffle and is immersed in water for a long time. The structure and use are different from the general electromagnetic flowmeter.
6. Electromagnetic flowmeter insert type electromagnetic flow sensor for large diameter. The sensor is inserted radially from the pipe opening to measure the local flow rate to estimate the flow rate with low accuracy but at a low price for the control system.
