Page 5: Proper Use
Proper use Safety □ 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",... -

Operating limits Operating limits Technical data 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. -
Page 9: Substitute Operating Data
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. -

Page 21: Removing The Preservation
Disposal After about six months storage check the oil level in the flowmeter and if necessary top up oil. Check the preservation of the outer housing and if necessary apply oil to the parts again. Notice: Store the preserved flowmeter cool and dry and protect it against direct sunlight. Notice: After a longer storage time the manufacturer recommends that you have the flowmeter recalibrated, see "Re-calibration of the flowmeters", page 29. -

Page 25: Electrical Installation
Electrical installation 1. Remove the protective covers and store them. 2. Install the flowmeter stress-free in the pipe system while taking the preferred direction of flow into account and ensure that the connections of the pick up remain accessible. 3. The screw-in length of the piping may not exceed the threaded length of the flowmeter, since the flow cross-section is narrowed and internal components can be damaged. - Page 26 Removing the flowmeter WARNING Risk of injury through emitted hot, poisonous or corrosive pumped liquid when removing the flowmeter. ► Observe the safety regulations for handling dangerous liquids. ► Ensure that the flowmeter is not under pressure. ► Collect the emitted pumped liquid safely and dispose of it in an environmentally compatible manner.
