Two flow transducers manufactured in acetal copolymer with brass compression fittings at both ends to fit 15mm diameter pipe connections.
Features and Benefits:
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
How it works A jet of liquid is directed at a free running turbine in a specially shaped chamber. The rate of rotation of the turbine is directly proportional to flow rate and the number of revolutions is proportional to the total amount of liquid passed. The passage of each turbine blade cuts a powerful beam of infra red light, this blocking is detected electronically.
Typical Applications:
Flow sensors and indicators are flow meter devices used to measure the amount of liquid, gas or vapour that passes through them and each type of flow sensor has its own specific applications and installation constraints. These flow transducers have been designed for use with mains and heating system waters. Flow sensors can be found in various applications that require control of fluids such as:
Washing machines
Showers
Dishwashers
Beverage dispensers
Water treatment
Cooling systems
