Proper use
Safety
Safety Proper use
□Use volumeters of the OME series solely for flow measurement of lubricating liquids that are chemi-
cally neutral and do not contain any gas or solids content.
□Volumeters require the operation with clean liquids. If coarse contamination, solid particles in the
liquid or abrasive fine particles occur during operation, the volumeter has to be protected additionally
by a correspondingly dimensioned operating filter in the pipe system, see "Protect the volumeter
against contamination", page 21.
□Do not use volumeters outside the operating limits specified on the rating plate and in the chapter
"Technical data". Deviating operating data can result in damage to the volumeter. In the case of ope-
rating data that does not agree with the specification on the rating plate, please contact the manufac-
turer.
□Strong changes to the flow rate (e.g. rapid shutdown, pulsations ...) cause marked pressure differen-
ces on the volumeter and can damage the measuring unit.
▪The pressure loss of the volumeter must not exceed the values given in the chapter "Technical
data", see "Load capacity", page 11.
Safety instructions
The following safety instructions must be observed:
□No liability is accepted for damage arising through non-observance of the operating instruc-
tions.
▪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.
□Volumeters wear to different degrees depending on the respective operating conditions (pul-
sations, temperature …).
▪Do not continue to use volumeters that are operated contrary to specification or after damage.
▪Check the volumeters regularly.
▪Shut down damaged volumeters and replace worn volumeters immediately.
□In order for the warranty to remain valid, corrective maintenance carried out during the war-
ranty 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 specification of the installation
location.
□In case of systems with an increased potential of danger to humans and/or machines the fai-
lure of a volumeter 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, combusti-
ble). 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.

Operational limits
Technical data
Technicaldata Operational 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 volumeter.
If no operating data are provided by the orderer, standardized substitute operating data are used.
Maximum values
The following table shows the respective maximum values that, however, may not occur simultaneously.
In addition, the operational limits of the corresponding end connection, of the sealing material and of the
connection box are to be observed.

Noise levels
Technical data
Substitute operating data
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 volu-
meter. In addition, the operational limits of the corresponding end connection, of the sealing material
and of the connection box are to be observed.
Tab. 2 Substitute operating data
Noise levels
The sound pressure level of the volumeter amounts to less than 70 dB(A).
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.
Auxiliary heating
If the customer's auxiliary heating systems are installed, please contact the manufacturer.
►Observe the values in the corresponding table, see Tab. 5, page 15.
