Chloroprene rubber(CR), polyurethane rubber(PU)

SI-3109 Large Diameter Pipe – Electromagnetic Flow Meter for Sewage/Wastewater,
is composed of insertion electromagnetic sensor and electromagnetic flow converter,
used to measure the conductive liquid that electrical conductivity is greater than 5 us/cm,
it is used to measure the water, sewage, acid, alkali and other medium.
Suitable for measuring the large pipe of diameter DN300~DN3000mm.
Installation can be divided into a online installation type of the cut-off valve,
and water control installation type without stop valves.
  • Non-invasive, no moving parts flow sensing technology
  • Accuracy 0.5% of actual flow
  • Calibration pre-programmed to user’s specific applications
  • Measures liquid flow in 2 to 36 inch
  • Operates in high temperatures up to 170°F
