SI-3501 Thermal Mass Flow Meter

SI-3501 Thermal Mass Flow Meter is an instrument measures flow rate, according to thermal properties of gases.
Detecting constant temperature difference of the medium,
the flow meter can directly measure fluid mass flow,
without requiring temperature and pressure compensation,
to provide high accuracy measurement result.
DiameterDN10~DN6000mm
Accuracy±1%
Temp. range-10~350℃
PressureMedium pressure≤10MPa
Flow rate0.5-100m/s
ProtectionIP67 (sensor part)
  • Temperature and pressure compensation is not necessary, measurement process is simple and accurate.
  • Could measure mass flow or standard volume flow rate of gas.
  • Range ratio 100:1, could measure gas flow from 100Nm/s to 0.5Nm/s and be used for gas leak detection.
  • Good vibration resistance, long service life. No moving parts or pressure detecting parts, accuracy will not be affected by vibration.
  • Easy installation and maintenance.
  • Adopt overall digitizing circuit measurement to ensure high accuracy.
  • Flow meter is with RS485 communication, could be part of automation and integration of your facilities.
