Woltman well water meter WB-N

Well water meters are meters from type Woltman perpendicular with a special design of the housing.

These can be installed as wellheads in place of a 90° elbow in accordance with DIN 28537 and DIN 28637. The housing is specially adjusted to the conditions in well systems. The well water enters the bottom of the water meter, flows through the vertical turbine and is directed out of the meter again at right angles.

The special construction of our turbines guarantees low starting flows and also provides sufficient reserves in the overload range even to be able to record high flow rates reliably. The internal and external coating protects the meter permanently against corrosion. Mineral deposits in the water are unable to damage the dry dial register. The design is ideally suitable for narrow well shafts with small dimensions. There is no need to provide an extra installation location for a Woltman meter.
