Irrigation water meter Woltman WI-N

The WI-N water meter is designed fur use with heavily contaminated water, e.g. in agriculture, in sewage treatment plants or wastewater systems.

This field of application requires particularly robust meters that also function reliably under the most difficult conditions. Our irrigation meters guarantee this by positioning the measuring insert in the upper section of the pipe, where there is generally only a small number of suspended particles in the running water. The meter easily takes a level of impurity of up to 30% in its stride. Where there is very heavy contamination, external filters can be inserted upstream of the water meter. The factory-tested measuring insert is the same for all meter sizes and can be delivered with the following measurement accuracy:

Qmax-Qt: ± 3% (value class A+B)
Qt-Qmin: ± 5% (value class A)

The mechanical counter is completely encapsulated and hence protected against impurities. As standard, the meters are supplied with a lockable protective metal cap[nbsp] which acts as a dependable protection for the counter, even in harsh conditions. Reed pulser can be retrofitted at any time without damaging the calibration seal.
