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.
The measurement devices run with low friction, gentle and with 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 flowmeter OMP offers.
