This series of water meters is developed to measure the total quantity of water consumed in households and industrial facilities.
Construction:
The counter is sealed off and does not come into contact with the water.
Coupling between vane wheel and counter by means of magnets.
The vane wheel rests on a stainlees steel pivot with a sapphine top. This results in a low friction and minimum wear.
The vane wheel cup is designed with large openings, making the water meter less prone to blockages and able to operate with low loss of pressure.

This type of water meter is developed to measure total water consumption in a water supply system.
Construction:
The counter insert can easily be taken out for inspection or for replacement without having to disassemble the casing.
The counter is a hermetically sealed dry unit.
Magnetic coupling between vane wheel and counter ensures longevity.
The use of identical components for several sizes of water meters minimizes spare parts requirements.
Woltman Meters are open-type water meters, suitable for use with a fluctuating load.
Low start-up and low pressure loss.
