Principle
Sanitary flow meter works based on Faraday's law, and measure conductive medium with conductivity more than 5 μs/cm and flow range from 0.2 to 15 m/s.
Union electromagnetic flow meter is sonsist of proprietary technological sensor and transmitter,it's mainly used to measure  slurry,cement paste and high pressure water infusion  in geology, oil exploration.
Application
According customers requirements,we can provide various electromagnetic flowmeters widely used following industries,

      • Chemical
      • Medicine
      • Beverage
      • Iron and steel
      • Water supply
      • Electricpower
      • Water treatment

Features
      • No moving partes,no pressure loss
      • Accuracy:±0.2% of the measured value + 0.3m/s
      • High accuracy for low flor rate and can measure duplex flow
      • Double frequency excitation,stable zero point 
      • Built-in ground electrode,no need grounding ring

 

          Installation Notice

Installed at the lowest point and vertical upward direction              Install exhaust valve at the downstreat of flow meter

Don’t install at the highest point and vertical downward diection          when drop is more than 5m



           
Installed at the lowest point when used in open drain pipe        Need 10D of upstreat and 5D of downstreat



     


Dont’ install it at the entrance of pump, install it at the           Installed at the rising direction
exit of pump

Main performances of the electrode materials
Electrode material Applications
sainless steel SUS316 Applicable in water,sewage and corrosive mediums.
Widely used in industries of petrol,chemistry,carbamide,etc

Stainless steel covered

with tungsten carbide

 Applicable in mediums of no corrosive and low abrasion.
Hastelloy B(HB) Having strong resistance to hydrochloric acid of any consistance which
 is below bioling piont.
