The counter of the new EKTD has been conceptually newly thought through and technically refined. The result is a counter with a shielded magnetic coupling which delivers virtually perfect results in terms of precision and measuring stability. Thanks to a wide range of technical options, the EKTD is optimally equipped for the future.
The EKTD makes a technical leap forward in development with its newly developed modulator disc. This makes possible non-reactive, electronic scanning with a variable resolution and is the basis for remote reading via radio, M bus or pulse module.
Pulse-ready
Both the ETKD 7 reel model with magnetic counter and the 8 reel model with modulator disc provide the option of reading the counter data remotely.
M bus-ready
Using a special add-on M bus module, the ETKD 8 reel counter model with modulator disc can be integrated into an M bus system, in which all counters on a property are connected together and can be read centrally.
Radio-ready
With the addition of an add-on radio module, the ETKD model with modulator disc and 8 reel counter can be read via radio (WM bus as per OMS). A radio module transmits the counter data to a radio modem and these are relayed to a PC or hand-held computer via Bluetooth.
Our developers succeeded in combining the high-precise measuring ETKD-insert with a body of pressure-tight plastics, suitable for use with potable water. The result is the innovative ETKD-L.
The composite housings of the Water Meter consist of a polymer, as light as it is highly stable, which has been used in the automotive industry and in the manufacture of sports equipment and containers for drinking water for many years. The result: extremely low weight with the highest stability and resilience. In addition, the Plastic Water Meters are resistant to corrosion.

The new series of our volumetric piston meters with protected dial are an improvement of the classical RNK. Our developers succeeded in combining the millionfold proved and high-precise measuring insert with a body of pressure-tight plastics, suitable for use with potable water. The result is the innovative RNK-L-RP-N.
A very low starting flow and reliable performance even with aggressive or dezincification water qualities are its main features. The protected roller counter is reliably readable even under demanding climatic conditions.
The construction principle of the RNK-L-RP-N with direct transmission from the measuring chamber to the counter ensures by standard protection against magnetic or other manipulation attempts or interference.
RNK-L-RP-N is equipped with pulser (Reed) for remote readout.
Performance Characteristics
Its main features are a low starting flow and reliable perfor- mance even with difficult water qualities or dezincification effects. Constant development guarantees accurate measuring results and the best long-term stability.

Performance Characteristics
In order to ensure this, inlet and outlet zones are required. T-pieces, elbows or partially open valves create eddies in the water and an irregular flow-rate profile. If this turbulence reaches the meter, it will have a long-term effect on the measurement results. This problem can be solved by using the honeycomb rectifier.
32 square, axial channels rectify the turbulence of the water inside the pipeline.
There is a punched disc at the outlet of the honeycomb unit, the open cross-section of which is equal to approximately half the cross-section of the pipe. The water flowing in is braked and the subsequent square channels rectify any remaining turbulence.
Pressure loss due to the honeycomb rectifier is approximately 0.1 bar at a flow-rate of 3 m/sec.
The metal flange of the punched disc serves to attach the rectifier between two flanges and the honeycomb unit faces downstream.

This has been developed for very precise recording of amounts of water, above all in the starting range. Combined with a wide load range, this type of meter is used either for highly precise measurement of highly variable flow rates or as an alternative to the classic combination meters, with main and secondary meter.
In contrast to Woltman meters, the ETK-N/ETK-M does not require an inlet zone, since, as a single-jet meter, it is insensitive to swirling flows. Approved for horizontal installation position, this meter type is very flexible to use and can be an alternative in almost all areas of application of the classic combination meter.
Đồng hồ đo nước cho tốc độ dòng chảy cao với độ chính xác đo cấp C - đồng hồ đo nước số lượng lớn ETK-N-C một tia chính xác của chúng tôi.
Điều này đã được phát triển để ghi rất chính xác lượng nước, hơn hết là trong phạm vi ban đầu. Kết hợp với dải tải rộng, loại đồng hồ này được sử dụng để đo chính xác cao tốc độ dòng chảy thay đổi cao hoặc thay thế cho các đồng hồ kết hợp cổ điển, với đồng hồ chính và phụ.
Trái ngược với máy đo Woltman, ETK-N / ETK-M không yêu cầu vùng đầu vào, vì là máy đo một tia, nó không nhạy cảm với dòng chảy xoáy. Được chấp thuận cho vị trí lắp đặt nằm ngang, loại đồng hồ này rất linh hoạt để sử dụng và có thể là một sự thay thế trong hầu hết các lĩnh vực ứng dụng của đồng hồ kết hợp cổ điển.
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.
Applications
The ZENNER Bulk water meter WPD / WPHD is specially constructed for the measuring of high flow rates with a mainly constant flow rate profile. Due to the robust design, WPD / WPHD can cover a wide measuring range and provide accurate measuring results over a long period. So it covers almost all measuring tasks in the drinking water supply and distribution.
The housing of the WPD / WPHD was flow-optimized. The mesuring insert was newly constructed as a replacable metrological unit according to european MID. In combination with an up-to-date bearing of the impeller a good linearity and long-term stability of the error curve can be achieved. The robust copper-glass-register is non-diffusive and protected against condensation. It also works reliably under the hardest conditions (e.g. in flooded pits or shafts).
The WPD / WPHD is optimally prepared for remote reading. Retrofitting of electronic communication modules (EDC radio, EDC M-Bus, EDC pulse) and conventional Reed sensor is possible at any time and without violating the calibration seal.

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 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.

The WPVR was designed to record fluctuating flows, for use in drinking water distribution and industrial applications. The main meter is based on the proven Woltman parallel technology. As a secondary meter a rotary piston meter is used, with which even small flows can be reliably recorded.
All materials, which are used in the drinking water section, comply with the required standards, guidelines and the current German drinking water approval (other country-specific drinking water approvals on request)
Applications
Two one-piece manifold bodies with integrated sliding pistons are embedded in the heat and sound-insulating casing. Meter and valves can be assembled simply in a single process without prior alignment.
The assembly block is available in all standard connection variations and dimensions and is thus suitable for assembly in masonry, rear walls and sides as well as for wall-mounted installation.
The ZENNER Block 2" is especially suited to confined installation situations. A one-piece rosette encloses both water meters and the water shut-off valves. The assembly block can be quickly separated from a duo-block to a mono-block by means of a saw groove.
