ElectroMagnetic Flow Meter DN200, are used for central air conditioning heat | cooling supply management

Description

The magnetic flow meter externally powered by 100-240VAC or 24 VDC. Low power requirements also make it ideal for solar and comparable power sources. Rate and total indication is standard, as is a solid state pulse / frequency /

4-20mA output, that allows connection to a data logger.
The display housing can be either integrated or remote. A shielded power/pulse output cable with DIN connection

is included with the meter.

The electromagnetic flow meters use Faraday’s Law of Electromagnetic Induction to determine the flow of liquid in a pipe. In a magnetic flowmeter, a magnetic field is generated and channeled into the liquid flowing through the pipe. Following Faraday’s Law, flow of a conductive liquid through the magnetic field will cause a voltage signal to be sensed by electrodes located on the flow tube walls. When the fluid moves faster, more voltage is generated. Faraday’s Law states that the voltage generated is proportional to the movement of the flowing liquid. The electronic transmitter processes the voltage signal to determine liquid flow.

Mounting notice

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

  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
