18 Multi-jet wet dial meters Options for multi-jet dry dial meters Copper can (protection class IP 68) Optionally all the dry dial multi-jet and positive-displacement meter models are also available with protection class IP68. In this variant, the register is flood-proof (IP68) due to hermetically sealed roller register made of glass/ copper. Even in case of flooding, the register operates reliably. Anti-magnet ring Water meters and other measuring devices may slow down in the vicinity of a magnet or even stop. In order to prevent a reduction in the accuracy of measurement or manipulation by magnetic influences, all dry dial and positive displacement meter models are equipped as standard with an anti-magnetic ring. Anti-fog tools (wiper option, nano coating) Due to lack of insulation in the house connection or due to extreme climatic conditions, e.g. with high humidity, condensation may form on the lens of the water meter. ZENNER offers to provide the lenses with a nano coating, so that condensation can not occur. For optimal viewing in all conditions, the registers of the dry dial and positive displacement meters can also be optionally equipped with a wiper. The wiper allows the reading of the digit rollers even with condensation in the register. 36

20 Multi-jet wet dial meters RTKD-N and RTKD-M Positive displacement dry dial meter for cold water Equipped with the newly developed dry dial D-register by ZENNER, the new RTKD positive displacement meter is a meter for all who place the highest demands on reliability and measuring accuracy. The RTKD records the flow rate using the volumetric measuring principle and, in this way, guarantees extremely precise consumption recording and accounting. The RTKD positive displacement meter also has a high measuring range and a very good measurement stability. The reliable workmanship and durability of the RTKD increase the potential period of use and hence the cost-effectiveness of the meter. RTKD-N Due to a variety of technical options, the RTKD has been optimally equipped for the future. The newly developed modulator disc in combination with the new EDC communication module enables nonreactive electronic scanning 1 1 with a variable resolution and is the basis for automated meter reading via radio, or impulse module.
