Inside a Turbine / Hall flow sensor

Peel from the case to the element. Follow the readout through this conceptual model.

Layer 1 of 3 / Outside

Case: inline body with inlet and outlet

Water enters through the inlet and leaves through the outlet, turning a turbine wheel. [Water Flow Sensor: Working principle]

Teaching view: The conceptual black inline body has threaded stubs, dark bore markers and a flow-direction label. The markers do not form through-bores; fine plumbing details are illustrative.

The measurement to rememberPulse counts convert to litres using the selected flow sensor calibration factor. [Water Flow Sensor: Working principle]

1 · Case: inline body with inlet and outlet

Water enters through the inlet and leaves through the outlet, turning a turbine wheel. [Water Flow Sensor: Working principle]

Teaching view: The simplified black body has threaded connections for the inlet and outlet pipes. A label marks the direction of water flow through the body.

2 · Board / module: Hall pulse readout

A magnet turns with the wheel; the rotating magnetic field triggers Hall-sensor pulses. [Water Flow Sensor: Working principle]

Teaching view: A green circuit board with a magnetic-field sensor sits above the white water-driven wheel and its red magnet. The board stays outside the water path. The arrangement is simplified for teaching.

3 · Element: turbine and pulses per litre

Use the calibration factor for the selected sensor: the number of output pulses per litre of water that passes through it. [Water Flow Sensor: Working principle]

Teaching view: The white turbine wheel carries a red magnet. As water turns the wheel, the magnetic-field sensor produces pulses. In a worked example, suppose calibration gives 500 pulses per litre. Counting 1,000 pulses gives 1,000 pulses divided by 500 pulses per litre = 2 litres. Use the actual sensor’s calibration for real measurements.

Explode separates the conceptual layers; X-ray makes the case translucent. External package dimensions follow the model specification; internal teaching geometry is conceptual, not to scale, and is not manufacturer CAD or a wiring diagram.
