The FLOW 38 Batch type of induction meters are suitable exclusively for measurement of volumetric flow of electrically conductive liquid substances with a minimum conductivity of 20 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.

This will serve as an additional safety measure for detection of non-flooded tube. The responsibility for suitability and adequacy of application of induction flow meters is borne by the designer or possibly the user himself. Manual FLOW 38 BATCH Page 8 (total 43) 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 38 BATCH Page 9 (total 43) 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 38 BATCH Page 10 (total 43) COMAC CAL s.r.o.

Similarly, fasten the wires for supply voltage and control outputs. At this stage the device is ready to operate. The internal control board is already connected with a measuring device – this has been done inside the COMAC CAL factory. If this is not desirable, do not interfere with the wiring.

Applying a signal to the GND terminal 7 or 8 you can start or stop the batch. These terminals are in batching devices already connected to the control buttons. Manual FLOW 38 BATCH Page 18 (total 43) COMAC CAL s.r.o.
Terminals 1 and 2 are used to control the relay valve batching device. These terminals are in batching devices already connected to the control board with relay outputs. Data output The Flow 38 Batch meter can be provided with RS485 communication interface with M-Bus protocol according to EN 1434-3 or ModBus RTU. Protection degree The meters meet all the requirements for IP 65 protection degree.
The meter or flow meter parameters are set by the manufacturer in accordance with the purchase order. If these values are not indicated in your purchase order, the meter will be set up using the default Manual FLOW 38 BATCH Page 20 (total 43)
Perform electrical connection always after powering off. FLOW 38 BATCH OPERATING INSTRUCTIONS The meter is provided with two external buttons on the side of the electronics housing and with three internal buttons on the bottom of the measuring electronics PCB which is accessible after unscrewing the front glazed cover.

Activates and deactivates monitoring of measuring tube filling. If the meter was ordered without the testing electrode, the flooding test cannot be activated. Two levels of the empty tube test activation are available for standard conductivity ON(1) and for increased conductivity ON(2). Manual FLOW 38 BATCH Page 27 (total 43) COMAC CAL s.r.o.
The display shows the simulated flow and current and impulse outputs of the meter correspond to this data. Such a simulated flow is not registered in the volume registry, of course. Manual FLOW 38 BATCH Page 28 (total 43) COMAC CAL s.r.o.
If the medium flows through the sensor against the arrow on the sensor, select the NEGATIVE direction. If you wish to make the change, press E. Manual FLOW 38 BATCH Page 29 (total 43) COMAC CAL s.r.o.
This applies to calibration of the meter as well. Before activating this function, it is useful to record or make a back up of the data of all counters. Manual FLOW 38 BATCH Page 30 (total 43) COMAC CAL s.r.o.
