Measuring the quantity of a liquid, gas or electricity

Water or fluid flow can be easily measured by mounting a propeller just outside the water pipe and connecting it underneath the plastic casing of the meter. The water flows through the pipe and spins the propeller. A magnet is mounted on the propeller and a Reed Sensor is mounted outside of the plastic casing. In this case, each propeller rotation is counted as the magnet rotates past the Reed Sensor. The rotations are tallied and electronic circuitry converts the rotations to volumes of water (or other liquid) flowing through the pipes.

In a similar manner, the flow of gas and electricity can also be measured.

Our MK3 Sensor is often used for such applications, but we have many other sizes and shapes also worthy of your consideration.
