Product Details

Liquid Flow Sensors

Two flow transducers manufactured in acetal copolymer with brass compression fittings at both ends to fit 15mm diameter pipe connections.

Provides a pulsed output proportional to flow rate
LED and photodetector are separated by a turbine mounted on sapphire bearings
LED requires an external current limiting resistor (dependent on supply voltage)
Suitable for use with mains and heating system waters etc.
Rise/fall times 60/6ns
Output voltage 200mV (low); VCC (high)
Diode: Forward current 10mA, Power dissipation 100mW


Not suitable for use with strong mineral acids/solutions, strong or searching solvents.
