FlowX3 F3.00 Paddlewheel Flow Sensor

F3.00

The simple and reliable paddlewheel flow sensor type F3.00 is designed for use with every kind of solid-free liquids. The sensor can measure flow from 0.15 m/s (0.5 ft/s) producing a frequency output signal highly repeatable. A rugged construction and a proven technology guarantee exceptionalperformances with little or no maintenance required. A specially designed family of fittings ensures an easy and quick installation into all pipe materials in sizes from DN15 to DN600 (0.5" to 24").

Operating principle
The flow sensor consists of a transducer and a five-blade open cell paddlewheel using insertion technology. The paddlewheel is equipped with a permanent magnet integrated into each blade. As the magnet passes close to the transducer a pulse is generated. When liquid flows into thepipe, the paddlewheel is set in rotation producing a square wave output signal. The frequency is proportional to the flow velocity. The sensor is installed into the pipe using a wide range of insertion type fittings supplied by the flow sensor manufacturer. In the versions with 4-20 mA or MIN alarm output, an additional IP65 housing is plugged onto the sensor. Output signals are available on aterminal strip inside via a PG11 cable gland. n The sensor F3.30 with 4-20 mA output and the sensor F3.15 with MIN alarm output require a power supply from 12 to 24 VDC. n The nominal measuring range is from 0.15 to 8 m/s (0.5 to 25 ft/s).

Engineering Data

The flow sensor is available with Hall effect transducer (standard) and Coil effect transducer (battery operated). n The Hall sensoroperates with a power supply from 5 to 24 VDC @ < 30 mA. n The Coil sensor operates with a power supply from 3 to 5 VDC @ < 10 mA. n The standard output is a square wave with a frequency of 45 Hz per m/s (13.7 Hz per ft/s) nominal. n The output signal is provided directly via electric cable or via a cable plug according to DIN 43650-B/ISO 6952. Supplied cable is standard 8 m (26.4 ft) long, with amaximum length of 300 m (990 ft) for Hall sensor and 16 m (52.8 ft) for Coil sensor
