SECTION 9: COMPONENTS
Vortex Flowsensor is a combined flow rate/temperature gauge projected for high volume water production. It
is made of composite material, while the sensor is made of a silicone base realised with MEMS technology.
The gauge is corrosion resistant.
Measuring range 5-100 l/min / 0-100 °C
Immediate time response < 1 s
Maximum pressure > 16 bar
Temperature/flow rate gauge VORTEX FLOWSENSOR (VFS) 5 - 100 l/min
