KRAL Volumeters are classified in series. The classification indicates the flowmeter's material or its application range.

All models start with OM, which stands for Oil Meter, from our initial applications of the meters.

The following table gives an overview of our Volumeter product line:

Series
OMG Universal 0,1 to 7500 (l/min)
OMH High pressure 0,1 to 3000 (l/min)
OMK Chemically resistant 3,5 to 1050 (l/min)
OMS Stainless 0,1 to 150 (l/min)
OME Economy 0,1 to 7500 (l/min)
OMX Custom design

The Volumeter product line is complemented by the BEM 4U flow management unit. The BEM 4U is not only suited for KRAL Volumeters, but for all flow measuring devices with pulse output.

OMG Series - Universal
The OMG series used for a wide spectrum of applications (G=general). They are manufactured of gray cast iron. The multiple possibilities become obvious from the wide flow range of 0,1 to 7500 l/min, the allowable system pressures up to 250 bar and the temperature range of -20 to +200 °C.

OME Series - Economy
The OME series is the economy variation. This product line meets the requirements of a cost-effective flow meter. With a flow range of 0,1 to 150 l/min, a permissible pressure of up to 40 bar and a temperature range of -20 to +100 °C we concentrated on the operating parameters required most frequently.

OME has an aluminum housing. The measuring signal is measured directly at the spindles. The housing design is optimized for production. Like all our flowmeter series, the high measuring precision is retained.

OMH Series - High Pressure
The OMH series is for the high-pressure range. In its standard configuration, it is specified for a system pressure of up to 420 bar. For special applications on oil rigs we have already designed a meter for up to 1035 bar. The specific task of a high-precision flowmeter for high-pressure applications is that the measuring chamber must not be changed under pressure in such a way that the precision is affected. The KRAL Volumeter is an in-line meter, the fluid flows through the device without redirection. This allows for a small housing design. Amongst the high-pressure meters available on the market, the OMH is one of the most compact.

OMK Series - Chemically Resistant
The OMK series has plastic spindles made of PTFE and a stainless steel housing. These Volumeters are chemically resistant to a large number of fluids and is used particularly with aggressive and non-lubricating fluids.

OMX Series - Custom Design
For specific customer requirements we can provide special designs and materials. These meters carry the designation OMX.

OMS Series
OMS (stainless steel) is manufactured completely from stainless steel (14301 or 14401).

Flow Management System BEM 4U
In order to easily evaluate the measuring signals of the KRAL Volumeters, KRAL developed the BEM 4U.

The BEM 4U is especially designed for flow measuring tasks. It provides an understandable display and operating concept and is suitable for all flow meters with pulse output.
