How to choose the grounding ring of electromagnetic flowmeter

Electromagnetic flowmeters are mainly designed for water metering and trade of water supply enterprises. They are waterproof, anti-corrosive, anti-interference and anti-lightning. There

are no moving parts or flow-blocking parts in the pipeline of the electromagnetic flowmeter, and there is almost no additional pressure loss in the measurement. Regarding the selection of grounding rings, the following is a brief introduction so that novices can better familiarize themselves with the relevant knowledge.

1. Protection ring: F46 lining sensor should use a protection grounding ring, which is fixed to the flange by screws to protect the flange of the lining from damage.
2. The material of the grounding ring is stainless steel, and special requirements can be specified when ordering.
3. Standard grounding ring: On plastic and cathodic protection pipes with insulated inner and outer walls to prevent electrolytic corrosion, grounding rings must be installed on both sides of the sensor.
4. Neck protection ring: If the medium is highly abrasive, a neck protection ring should be used to protect the lining.

In actual work, the measurement results of the electromagnetic flowmeter are independent of physical parameters such as flow velocity distribution, fluid pressure, temperature, density, viscosity, etc.; the range can be modified online on site according to the actual needs of the user. (end)
