Proper use
Safety
Safety Proper use
□Use flowmeters of the OMP series solely for flow measurement of lubricating liquids that are
chemically neutral and do not contain any gas or solids content.
□Flowmeters require the operation with clean liquids. If coarse soiling, solid particles in the liquid or
abrasive fine particles occur during operation, the flowmeter has to be protected additionally by a
correspondingly dimensioned operating filter in the pipe system, see "Cleaning the pipe system",
page 27.
□Only use flowmeters within the operational limits specified on the rating plate and in the "Technical
data" section. Deviating operating data can result in damage to the flowmeter. In the case of
operating data that does not agree with the specifications on the rating plate, please contact the
manufacturer.
□Strong changes to the flow rate (e.g. rapid shutdown, pulsations ...) cause marked pressure
differences on the flowmeter and can damage the measuring unit.
▪The pressure loss of the flowmeter must not exceed the values given in the chapter "Technical
data", see "Load-bearing capacity", page 14.
Safety information
The following safety instructions must be observed:
□No liability is accepted for damage arising through non-observance of the operating
instructions.
▪Read the operating instructions carefully and observe them.
▪The operator-owner is responsible for the observance of the operating instructions.
▪Installation, removal and installation work may only be carried out by specialist personnel.
□Flowmeters wear to different degrees depending on the respective operating conditions
(pulsations, temperature, …).
▪Do not continue to use flowmeters that are operated contrary to specifications or after damage.
▪Check the flowmeters regularly.
▪Shut down damaged flowmeters and replace worn flowmeters immediately.
□In order for the warranty to remain valid, corrective maintenance carried out during the
warranty period requires the express permission of the manufacturer.
□Observe the general regulations for the prevention of accidents as well as the local safety
and operating instructions.
□Observe the valid national and international standards and specifications of the installation
location.
□In case of systems with an increased potential of danger to humans and/or machines the
failure of a flowmeter may not lead to injuries or damage to property.
▪Always equip systems with an increased potential of danger with alarm equipment and/or
bypass.
▪Maintain and check the protective/alarm equipment regularly.
□The pumped liquids can be dangerous (e.g. hot, dangerous to health, poisonous,
combustible). Observe the safety conditions for handling dangerous materials.
□Pumped liquids can be subject to pressure and can cause damage and/or personal injury
should leaks occur.

Technical data
Technic al data Operating limits
The values specified on the rating plate and the calibration certificate apply. The permissible operational
limits of individual values influence each other so that every application is checked individually by the
manufacturer when selecting the flowmeter.
If no operating data are provided by the orderer, standardized substitute operating data are used.
Load due to pressure pulsation
Maximum values
The following table shows the respective maximum values that, however, may not occur simultaneously.
In addition, the operational limits of the corresponding completion, of the sealing material and of the pick
up are to be observed.
Tab. 1 Maximum values
Strong pressure pulses in the system can reduce the lifetime of
the flowmeter.

The following table shows standardized values for the flow rate, temperature and viscosity. These
values can be used at the same time as maximum values without impairing the service life of the
flowmeter. In addition, the operational limits of the corresponding completion, of the sealing material of
the pick up and of the temperature sensor are to be observed.
Tab. 2 Substitute operating data
Sound pressure level
The sound pressure level of the flowmeter amounts to less than 70 dB(A).
Heating system
A heating system is not installed at the factory. The customer can optionally fit OMP-series KRAL
flowmeters with a trace heating system. The manufacturer recommends heating systems for high-
viscosity liquids that do not flow sufficiently if not heated, because bearing damage and destruction of
the device may otherwise result.
Trace heating system
Contact the manufacturer before installing a trace heating system.

Description
Function description
Function descript ion Description
As screw meters flowmeters belong to the group of rotating displacement meters. The fluid current
makes the measuring unit rotate. The displacement effect results from the continuous filling, axial
displacement and discharge of the volumes that are formed by the measuring housing and measuring
unit. The measured liquid flows around and lubricates all the rotating parts. Thanks to the displacement
principle, the flowmeter does not require inlet and smoothing sections in its supply and discharge.
Depending on the customer requirements, the flowmeters can be equipped with suitable end
connections for connection to various flanges.
Rolling bearings
The measuring unit is maintained without contact and with a low degree of friction in the housing of the
flowmeter by means of precision rolling bearings. Depending on the respective size, the following
bearings are used:
□Single-row deep-groove ball bearings
□Paired angular-contact ball bearings

Signal generation
Function description
Signal generation
A pick up samples the measuring pulses directly on the screw. The pick up generates a specific number
of pulses per flow volume unit – depending on the size and working point. This device-specific
characteristic is called the K-factor (unit: Pulse/Liter) and can be found on the rating plate and the
enclosed calibration certificate. Possible formats of the signals are:
□PNP
□NAMUR
The mounting method of the pick-up allows mounting without contact to the fluid to be measured. Two
different pick ups are employed, depending on the application (standard, or for use in areas where there
is an explosion hazard):
□Pick up based on the Hall effect
□Inductive pick up
Linearization
The calibration certificate contains a mean K-factor that has been determined for the flow range 10:1
and that can therefore be used across a wide flow range. However, the K-factor shows slightly different
values at different flow rates. These are also documented in the enclosed calibration certificate. If
highest measuring precision is required, it is therefore advisable, especially at strongly varying flow
rates, to take these different values into consideration by means of a "Linearization". The K-factors are
therefore fed into a suitable electronics unit across several interpolation values of the flow rate. The K-
factor relevant for the flow rate being measured is then determined by means of linear interpolation
between the two nearest interpolation values.
The viscosity dependence of the K-factors must also be taken into account. These are determined
during calibration at a viscosity of approximately 4.2 mm²/s. The influence of the flow rate on the K-factor
decreases at higher viscosities so that the mean K-factor can then also be used in a considerably larger
flow range without noteworthy errors.
Temperature compensation
If the flowmeter is additionally equipped with a temperature sensor, the current density of the flowing
liquid can be calculated from this measured value by means of a density table stored in the flow
management unit. A normalized volume measurement is then possible at which the displayed values
are converted to a reference temperature that can be selected freely. This ensures that measuring
errors caused by changes in the density due to temperature variations are avoided.
Flow direction detection
Systems with a changing flow direction as well as systems with pressure pulsations - that can also
cause a reversal of the flow direction - require the use of a second pick up. This additional signal (90°
phase-offset) and the incremental encoding inputs available in the KRAL electronic unit can be used to
determine the direction of flow and to take it into consideration when calculating the total values.
Junction box
The manufacturer offers a junction box that facilitates the electrical connection of the various sensors for
the flowmeters of the OMP series. For further information see "Accessories", page 42.

Transportation, storage and disposal
Transportation , storage and d isposal Unpacking and checking the state of delivery
1. Upon delivery unpack the flowmeter and check for transport damage.
2. Report damage during transportation immediately to the manufacturer.
3. Store the supplied pick up and temperature sensor for the installation.
4. Dispose of packing material in accordance with the locally applicable regulations.
Lifting the flowmeter
Storage
As a result of the calibration, the internal components of the flowmeter are wetted with calibration liquid
that has a preservative effect. In addition, a special anticorrosive agent is sprayed onto the interior of the
flowmeters before being dispatched. The connections of the flowmeter are fitted with protective caps.
Unless otherwise specified, the external components of the flowmeter are preserved with a single-coat
PU-based two-component paint. The preservation applied at the factory will protect the flowmeter for up
to six weeks, if it is stored in a dry and clean location. The manufacturer offers a long-term preservation
for storage times of up to 60 months. The flowmeter is additionally packed in hermetically sealing anti-
corrosion paper.
► Observe the chapters "Storage" and "Preservation".
Preservation
Preservation has to be carried out additionally under the following conditions:
Tab. 1 Check table for preservation
Preserving the flowmeter
1. Close a connection of the flowmeter with a blind flange.
2. Position the flowmeter vertically.
3. Fill non-corrosive and resin-free oil up to approx. 1 cm under the connection at the top, while turning
the measuring unit slowly, so that the measuring unit also comes into contact with it.
4. Close the upper connection with a blind flange.
5. Apply non-corrosive and resin-free oil to all the plain and unpainted parts of the outer housing.
WARNING
Risk of injury and/or damage to equipment should the flowmeter fall.
► Use intact and correctly dimensioned hoisting equipment in accordance with the total weight to be
