3.2.4 Electronic unit

The flow-meter electronic unit (see Fig. 5) is embedded in a plastic box with a steel sheet attached at the back for
vertical mounting. At the front panel on the box there are meter type designation and product name, production series
number, manufacturer's name and logo, two-line back-lighted display unit and a membrane keyboard. At the bottom of
the box under a removable plastic cover are plastic grommets for cables of circular cross-section (one PG 9 and six or
seven PG 7 grommets). The grommets are intended for tight fitting of cables of external diameter 6 to 8mm (PG 9) and
4 to 6mm (PG 7). At the bottom of the box there is also an earthing bolt. Both the front panel and the terminal board
cover can be sealed. Instead of one PG 7 grommet it is possible to fit a four-pole connector for the RS 485
communication line.
IMPORTANT NOTICE: Prior to putting the meter in operation, check the proper tightening of all grommets with cables
and blinding of the unused ones.
IMPORTANT NOTICE: The electronic unit shall not be exposed to direct sunlight.
