The patented SF800 is an all purpose flow meter with an excellent price-performance ratio.
It is suitable for a wide range of applications and large variety of fluids and covers flow velocities of 0.5 to 20 liter per minute at temperatures of -20 to +90 °C and an operating pressure of 6 bar (max 40 bar).

The SF800 is entirely made of high-quality plastics and composites with great chemical and thermal resilience.
The housing is made of PVDF, a high grade PVC, while the internal rotor of only 0.04 gram is made of Vectra, a liquid crystal polymer of very low weight.
Both materials are not susceptible to limescale.

An integrated PCB emits the infrared signal which is interrupted by the three blades of the rotor.
SMD components transform the interrupted signal into a pulse.
Due to the construction and geometry of the rotor housing, the flow sensors can withstand high pressure.
