The flow sensor is built into the pipework using adapters
Function
The transparent fluid admitted in the direction of the arrow is guided into a circular
motion via the swirl plate in the measuring chamber and directed onto the lightweight
triple vane rotor. The speed of the rotor is proportional to the flow rate and is detected
without feedback via the built-in optoelectronic infrared system (diode and phototransistor).
The integrated amplifier supplies a steady square wave signal, whereby the signal level
is dependent on the applied supply voltage (5 to 12 V DC).
Due to the particular design of the rotor, any gas bubbles (air bubbles) which may occur
in the fluid, are not dissolved, but carried along with the fluid.
Any assembly position is possible. The direction of flow is indicated by an arrow on the
sensor housing. Stabilizing zones up or downstream of the measuring device are not
necessary.
Flow rate fluctuations or pulsations do not have a negative influence on the resulting
measurement.
A protective filter is fitted on the inlet side.
All parts of the measurement housing in contact with media are made of polyvinylidene
fluoride (PVDF).
