SI-3104 Split Type Magnetic Flow Meter

SI-3104 Split Type Magnetic Flow Meter,
is a Stainless steel electromagnetic water flow sensor,
with pulse output, remote, IP68 flow meter.
SI-3104 Magnetic Water Flow Meter is applicable for all conductive liquids,
such as: Domestic water, industrial water, raw water, ground water, urban sewage,
industrial wastewater, the processed neutral pulp, pulp slurry, etc.
Accuracy0.5% to 2.0% of reading
Temp. range<60℃
Flow rate0.3~10m/s



Protection proof

IP65(compact type),IP67,

IP68(suitable for remote type)

SI-3104 intelligent electromagnetic flow meter is composed by sensor and transmitter.

The product is a induction instrument and operates with Faraday law of electromagnetic,

induction for measurement volume flow of liquid medium with conductive rate ≥50 us/cm.

  • High accuracy
  • Low cost
  • Little to no pressure loss
  • Readings that are unaffected by changes in density or viscosity
  • No susceptibility to bearing wear or other mechanical wear-and-tear issues
  • Moisture proof and waterproof  performance  is  good.   Suit for setting up and being used underground or wet environments;
  • Compare with other flowmeter, its advantage : big measurement range , low demand in straight pipe, high accuracy;
  • Low power consumption, one set flowmeter power consumption less than 20W.
