Cold and hot water meters from the Italian manufacturer Gioanola use their own system of pulse outputs.

The read head with a reed contact always senses a dial that is markedly marked and different from the others.

Therefore, if, as in the following figure, a target measuring one thousandth of m3 (0.001 m3) is measured, the weight of one pulse is one hundredth of m3 (0.01 m3).
