Signal detection via the pole wheelSignal detection via the pole wheelWith this method, the impulse transmitter detects the impulses via a pole wheel, which is attached to the measurement screw. Based on specifications and need, pole wheels with differing numbers of poles can be used. This enables a significantly higher signal transfer resolution. Signal detection via the pole wheel is used when a high signal resolution is needed, e.g., with test and calibration benches or with the use of a flowmeter in the lower flow range.

KRAL Flowmeters OMH Series.

For high pressures with highest accuracy.

With high pressure to an accurate measuring result.
The KRAL flow meters OMH series were especially designed to handle high pressures of up to 420 bar that can occur in the field of mechanical engineering, at test benches and in hydraulic applications.

Large flow ranges usually require large pipe cross sections and are therefore bulky flow metering devices. Due to the compact measuring element, the OMH series fits into a small housing and offers the significant advantage of being compact and lightweight in this pressure class, even for high flow rates.

The pressure resistance is provided by a very rigid housing, maintaining the compact dimensions, and at the same time the proven precision of the KRAL flow meters, even at extreme pressure levels.
