KRAL - Model OMH Series -High Pressure Flowmeters
With High Pressure to an Accurate Measuring Result.
The KRAL Volumeter OMH series is designed for high pressure application and can be applied to 6000 psi, a high pressure rarely achieved by other flowmeters. This is an extremely sturdy design apparent by the meter?s thick casing and through bolts. The inside hides a high precision measurement device.
Higher pressures are possible with KRAL Volumeter OMX.
- Suitable for high pressure.
- High accuracy.
- Robust design.
- No flow conditioning required.
- Easy Installation and operation.
- Follows any rapid fluctuations in the flow causes by pulsations.
- Bi-directional flow measurement.
- Multiple port connections available.
The first thing you`re interested in is reliable operating pressure. The KRAL Volumeter OMH can be used up to 420 bar. This high value is astonishing since it is hardly achieved by other flowmeters.
KRAL Volumeter* of series OMH are designed for high pressures. This is apparent even by looking at the instrument:
- robust, stiff casing,
- through bolts.
What cannot be expected: the inside hides a fine, high precision measuring movement. Fascinating, not so?
Even with high system pressure the measuring task requires high measuring accuracy.
OMH is a precision measuring instrument. Like the other KRAL Volumeter*, the OMH achieves its accuracy through
- the special screw geometry
- the accurate manufacture
- the calibration of each unit on our in-house test rig.
OMH has a stiff casing. The geometry remains even under high pressure. Consequently there is no impairment of accuracy.
Pressure is force per unit area.
High flow rates require large line cross sections and consequently large instruments.
The compact screw measuring movement requires only a small casing with small area. This means small forces.
For this reason the KRAL Volumeter OMH is an instrument in this pressure category with high flow rates and small dimensions and low weight.
The space for installing the flowmeter is usually limited.
KRAL Volumeter OMH are extremely sturdy and compact measuring instruments. This is due to the in-line arrangement of the measuring screws. Flow conditioning pipes are not necessary since the measurement is independent of the flow profile. The OMH mea- sures in any installation position. Flow mea- surement is possible in both directions.
