VFS - st.steel

Vortex Flowsensor Standard (VFS QT)

VFS_QT range

The VFS is a 2in1 flow and temperature sensor using a 5V stable power supply which generally outputs a ratiometric signal from 0.5-3.5V from Flow min. to Flow max.

 

It has a composite body and insert which goes inside a stainless steel pipe. Fittings for connecting it, can be provided as well.

Enclosure class is IP44.

 

Viscosity needs to be lower than 2 CSt (either lower concentration of glycol at room temperatures or higher concentration of glycol at higher temperatures).

The VFS 1-12 QT sensor can go up to 4 cSt viscosity and is therefore recommended in systems where the percentage of glykol is higher than normal.

 

The Vortex Flowsensor Standard QT comes in 5 ranges:

  • VFS 1-12 l/min        |    0.2-3.2 gpm
  • VFS 1-15 l/min        |    0.2-4 gpm
  • VFS 2-40 l/min        |    0.4-10.7 gpm
  • VFS 5-100 l/min      |    1.5-26.5 gpm
  • VFS 10-200 l/min    |     2.6-53 gpm
 

All VFS sensors also measure temperature from 0-100 degrees Celsius (32 to 212 degrees Fahrenheit).

Burst pressure >16 bar (232 psi).

Models available with threads for different worldwide standards (BSPP, NPSM, etc.)
