Magnetic RS485 Municipal Water Meters For Sewage Flow Measurement STP High Accuracy

Electromagnetic FlowMeters for sewage flow measurement in municipal water supply or STP

How to use the magnetic flow meter

The ElectroMagnetic flowmeters measure the velocity of conductive liquids in pipes, such as water, acids, caustic, and slurries. Magnetic flowmeters can measure properly when the electrical conductivity of the liquid is greater than approximately 5μS/cm. Be careful because using magnetic flowmeters on fluids with low conductivity, such as deionized water, boiler feed water, or hydrocarbons, can cause the flowmeter to turn off and measure zero flow.

Advantages

The magnetic flowmeter does not obstruct flow, so it can be applied to clean, sanitary, dirty, corrosive and abrasive liquids. Magnetic flowmeters can be applied to the flow of liquids that are conductive, so hydrocarbons and gases cannot be measured with this technology due to their non-conductive nature and gaseous state, respectively.

Electromagnetic flowmeters do not require much upstream and downstream straight run so they can be installed in relatively short meter runs. Magnetic flowmeters typically require 3-5 diameters of upstream straight run and 0-3 diameters of downstream straight run measured from the plane of the magnetic flowmeter electrodes.

Model selection

Applicable metering liquid:

• Conductive liquid media, conductivity > 5 µS/ cm
• Various Conductive aqueous solutions, water solutions, acid & caustics
• Abrasive slurries, sludges and grease bearing liquids, corrosive liquid, municipal tap water, waste water,dirty
  water, effluent, fibrous, viscous, paper mill, food & beverage

Non-applicable metering medial

• Industrial gas, compressed air, steam, or liquid with large content of gas
• Liquid is non-conductive or low conductive, like lubricating oil, clean oil, cryogenic, cooling water, pure
  water, clean gas, etc.

Notice on the selection of local type and remote type:

Remote type means the transmitter and converter display are mounted in different locations, it’s suggested to select
remote type in the following conditions:

• Ambient temperature or converter display sunshine temperature is over 60 ℃
• High humidity or corrosive air existed
• Serious pipe vibration
• Magnetic meter need be suspended or submersible, uneasily read out
• Other abrasive condition
