Axial flow meter


Radial flow meter

Flow Meter for Solenoid Valves

Sensor Construction

An axial turbine rotates in the water flow.Turbine may be placed either in the inlet or outlet. Rotation is detected by a reed switch or a hall sensor.

Technical characteristics

  • Medium temperature
    and water quantity: 250 m3 @ 95°C / 450 m3 @ 65°C / 800 m3 @ 25°C
  • Power supply: 5V
  • Output devices: Reed - Hall
  • K pulse per liter: 65 to 2300
  • Min. detected flow rate: 0.2L
  • Max. flow rate: 40L
  • Tolerance: 3 pulses


Pressure Sensor

Bitron pressure sensor, made by a Collpits circuit with a microprocessor, outputs a frequency signal proportional to the pressure detected in a pneumatic chamber.
Due to the tolerances of all the assembled components, each sensor has its own pressure/frequency curve.
Different ways can be used to correct the output frequencies:
Since many years Bitron choice is to mount a microcontroller that, through a software, translates the input pressure-frequency curve into the pressure-frequency table requested by the Customer.
As the electronic correction can be made on more points, this  calibration guarantees better tolerances in the whole range of pressure.
