Turbine water meters WI

Overview

The Woltman WI turbine irrigation water meter is recommended for installation at water intakes from open reservoirs, for measuring the amount of wastewater in sewer systems, as well as at agricultural facilities.
Wastewater meters are used to measure contaminated water, for example, in agriculture, wastewater treatment plants or wastewater treatment plants. These water meters have special requirements for work in harsh conditions.

Wastewater meters WI (irrigation) ensure this due to the fact that the measuring insert is located in the upper part of the pipe, where there is usually only a small number of suspended particles in the flowing water. The meter easily copes with pollution up to 30%. In case of very heavy contamination, it is recommended to additionally install external filters in front of the meter.
The manufacturer-tested measuring insert is the same for all meter sizes and can be supplied with the following measuring accuracy:

Qmax-Qt: ± 3% (values ​​class A + B)
Qt-Qmax: ± 5% (class A values)

The roller counter is completely encapsulated and thus protected from contamination. The meters are supplied as standard with a lockable metal protective cover that reliably protects the counter even under harsh conditions.

Retrofitting with pulse encoders can be carried out at any time without damaging the control seal.
NAMUR pulse, optical and inductive sensors provide all possible sensor options and make integration into a data transmission system very simple.

Pulse weight for Woltman meters
DN 40 - DN 125 standard 100 l / imp.
DN 150 - DN 300 standard 1.000 l / imp.
DN 400 - DN 500 standard 10.000 l / imp.

  • Water meters can be used for polluted water or in clean water as control
  • Easy maintenance thanks to removable measuring element
  • measurement accuracy according to class A
  • Water meter for horizontal and vertical installation
