1. APPLICATION AND DESCRIPTION
The electronic water meter with autonomous power supply, designed for metering of cold
water (0.1 -
30) °C (QALCOMATIC FLOW C - marked in blue) and hot water (30 - 90)
o
C (QALCOMATIC
FLOW H - marked in red) flowing in pipelines used in apartments, single family houses or other premises of
similar type. Water pressure must not be higher than 1.6 MPa.
It is a single-jet dry type meter. The water flow running through the meter rotates the impeller with a
mounted asymmetric metal plate, which changes the measuring coils decrement by rotational frequency,
which is then measured by the electronic block, that also records the number of rotations and calculates
the volume of water running through, and displays the readings on the indicator.
Remote data reading can be enabled by the use of optical interface, and by activating the wired M-
bus or wireless (radio) connection interface in the remote data collection system.
The meter is protected against the external effects of the magnetic field.
The counter shall be fastened to the meter frame using a transparent cap, which eliminates the
possibility of accessing the indication device without damaging the cap. This structure of the cap performs
the function of a seal.
The meters may be mounted both horizontally and vertically.
The meter mounting length may be 80 mm or 100 mm with connection tread G ¾B“ or 130 mm
with connection thread G 1B

Depending on the temperature class, the meter can be used for metering cold (T30) or hot
(T30/90) water.
