This is picked up by two electrodes in direct contact with the measured medium and evaluated in the electronic unit. The FLOW 45 type of induction meters are suitable exclusively for measurement of volumetric flow of electrically conductive liquid substances with a minimum conductivity of 50 S/cm (at a lower conductivity, upon agreement with the manufacturer).
In case of returning the meters for inspection or repair to the COMAC CAL s.r.o. factory, enclose please the completed form, see the last page of this manual. Without having one, we will not be able to handle your requirement for modification or possibly repair your meter correctly and promptly.

The difference of L and L distances of the sealing surfaces of the flanges before the flow sensor is installed must not be greater than 0.5 mm. Manual FLOW 45 Page 7 (total 28) COMAC CAL s.r.o.

The measurement accuracy is maintained in this way. Once the electrode is covered with the liquid again, the error message disappears and the flow meter starts taking measurement again. Manual FLOW 45 Page 8 (total 28) COMAC CAL s.r.o.

If the bolts are tightened too much during the installation of pipework components, deformation of the sealing surface may occur. In consequence, the torque values indicated in the table are used as a guidance for tightening the screws and bolts. Manual FLOW 45 Page 9 (total 28) COMAC CAL s.r.o.

In such cases, it is necessary to use the earthing rings for potential equalization. This holds true for two-phase or two- Manual FLOW 45 Page 11 (total 28)

For short pipelines, it is necessary to use flexible seals, for long pipelines, use flexible pipe elements (e.g. bends). Manual FLOW 45 Page 12 (total 28) COMAC CAL s.r.o.
The special cable for connection of the detached meter design must not be extended or cut short. In case of infringement of these requirements, measurement failures and significant inaccuracies may occur once the meters are connected. Manual FLOW 45 Page 13 (total 28) COMAC CAL s.r.o.
Power battery pack FLOW 45 is equipped with a battery power pack. When the voltage drops below the set limit, LOWBAT will be displayed on the display. The display of this sign indicates that a battery replacement request.

Right after installation, piping is filled with a medium so that the electrodes cannot dry off. Flow direction: The arrow indicates the direction liquid flow inside the sensor and thus the correct orientation of the meter's sensor for installation in piping.
