Signal detection via the measuring screwSignal detection via the measuring screwIn the case of signal acquisition via the measuring screw, the screw edge is detected by an impulse transmitter. Two edges per screw revolution are detected, which causes two impulses per screw revolution. Because a screw revolution conveys the exact volume of the measurement chamber, two impulses per measurement chamber volume are generated. This type of signal detection is an affordable solution for all conventional consumption and flow measurement applications.

KRAL Flowmeters OMP Series.

Robust solution for flow measurement of diesel and heavy fuel oil.

The OMP series flowmeters are designed specifically for fuel consumption measurement for marine applications as well as others, and can be used in booster modules and burners.

A perfect combination of precision and robustness: Due to the precise measurement chamber volume, a broad range of measurements with a precision rate of 0.1 % can be achieved. Pipe bends and T-sections have no influence on the measurement accuracy or performance of the KRAL flow meter.

The extreme robustness is achieved by the spheroidal graphite iron housing, which provides optimal protection for the precisely manufactured screws. The screws of KRAL flowmeters quickly follow the changes of the fuel flow rate, the fuel pulses and may even change its flow direction briefly.

Through the use of a high quality state-of-the-art hybrid bearing, the measurement devices also run with low friction, gentle and minimal pressure loss. Long lifespan, resistance to pulsations in the media, and efficiency across the entire product life cycle are just a few of the benefits that KRAL flow meter OMP offers.
