Introduction Of Woltmann Water Meter - EMS WT Series Operation & Installation Manual

1.4. Introduction of Woltmann Water Meter

WT-Series is a Woltmann-type water meter designed for measuring bulk flows of cold
potable water for revenue billing in commercial or industrial applications and distribution
system monitoring. WT-Series is manufactured from the highest quality materials for
maximum resistance to wear and corrosion. It features low starting flow rate, large turn
down ratio, stable measurements, low head loss, easy maintenance and installation. The
water meter has been produced according to standard EN 14154. The meter, designed to
measure the water consumption, has been proved a long-term reliable and accurate water
meter. WT-Series can provide management information to assist with effective distribution
management, reduce water losses from leakage and improve customer service. The
measuring principle of WT-Series water meter is as follows:
As water flows through the inlet of the flow straightener, the impeller bearing will push
the impeller to rotate. The impeller bearing is equipped with permanent magnets. The water
meter has sensing components which can detect the rotation and send signals to the
electronic register. The electronic register will receive the magnetic signals and then
transform the magnetic signals into flow rates. All flow rate data can be shown on the
electronic register.
