Air Velocity Transmitter


Air Velocity Transmitter

Mass Flow Measurements of Liquids is recognized amid successful Manufacturers, Exporters & Suppliers of Air Velocity Transmitter. The air velocity transmitter is delivered individually packed with standard accessories (see accessories). VT-D-R relay model is always equipped with display. The switching point and the hysteresis of relay can be configured by, push button and display user interface.

  • Highly Accurate OEM Digital Velocity Transmitter
  • Rugged gas flowmeter with no moving parts
  • Linear output signal with Flow Velocity
  • Eliminates gross errors of volumetric flow measurement
  • +/-3% FS including linearity, repeatability, hysteresis & thermal coefficient
  • Wide range of gas compatibility - only stainless steel and Ceramic in the gas path
  • More robust than hot wire or MEMS sensors

Details
  • The MFM has been developed using the 4 year’s mass flow measurement & control experience within MFML to produce a practical, low cost, rugged flowmeter suitable for demanding industrial applications.
  • There are no moving or delicate parts within the flow passage so the MFM is therefore very rugged indeed.
  • They provide 5 times better performance with an electri- cal output linear with flow, which may be used for logging and control purposes.
  • The unobstructed internal flow passages are easily cleaned with suitable solvents should the flowmeter become contami- nated in use.
  • With a temperature range from 15 to 50°C, the MFM performs well in elevated gas temperatures and ambient environments.
