Zenner RTKD positive displacement meter

The RTKD meter is a new mechanical dry dial single-jet displacement meter (oscillating piston meter) with magnetic coupling. The reliable meter measures the flow rate using the volumetric principle, guaranteeing an especially accurate reading.

The reliability and manufacturing quality ensures the longevity and cost-efficiency of the meter.

The additional devices of the RTKD meter ensure that the device will be operational in the future. The new modulator in cooperation with the new communication module allow to read data with different frequencies, which is a solid basis for the automatic long-distance reading of data with a radio (wMBus), Mbus or impulse module.
