GMF701-G Sea water hot water sulfuric acid hydrochloric acid nitric acid electromagnetic flow meter
Product Overview
GMF701-G electromagnetic flowmeter is a flowmeter that performs flow test according to Faraday's law of electromagnetic induction. The advantage of the electromagnetic flowmeter is that the pressure loss is extremely small and the flow range can be measured. The ratio of the maximum flow to the minimum flow is generally 10:1 or more. The applicable industrial pipe diameter range is wide, up to 3m, the output signal and the measured flow are linear, the accuracy is high, and the conductivity can be measured >5μs/cm. Acid, alkali salt solution, water, sewage, corrosive liquids, and fluid flows such as mud, slurry, pulp, etc.
Electromagnetic flowmeter is widely used in petrochemical, steel metallurgy, water supply and drainage, water irrigation, water treatment, sewage treatment station (environmental sewage control, chemical sewage, electroplating sewage), papermaking
Process flow measurement and control of production companies in (pulp), mud, medicine, food and other industrial and agricultural industries.

Product Details
Application
Sewage treatment can be divided into many categories, and the current application range of electromagnetic flowmeters is relatively wide. Mainly used in the environmental protection industry, the rapid measurement of wastewater is mainly for the purpose of measuring and controlling the flow. Sewage treatment is relatively complicated, and it is necessary to confirm various factors such as medium, temperature, pipe diameter, and linkage method. The most important thing is to confirm both the medium and the temperature. Here are a few representative examples of wastewater treatment.
Domestic sewage treatment: domestic sewage is relatively conventional, the medium is generally not corrosive, the temperature is also normal temperature, and there is no impurity after the primary treatment. Therefore, in the choice of electromagnetic flowmeter, you can use 316L electrode, rubber lining, flange connection. Of course, this is not absolute, there are other configurations available!
Sewage treatment plant dewatering machine room use: This is a necessary equipment for the sewage treatment plant. The flow rate of this equipment is all with sludge or other impurities. If it is corrosive, it needs to be confirmed according to the site. The conventional configuration is 316L electrode and PTFE lining mostly.
