MULTICAL® 62 • Water meter
The accumulated water consumption to be used for billing purposes is displayed in m
3
(cubic
metres).
Various communication modules and power supplies can be added. The utility can replace com-
munication module and battery.
If a longer distance (up to 10 m) is required between low sensor and display unit,
Pulse Transmitter (type number 66-99-618) can be used.
See instructions 5512-587 for further information.
Smaller cold water meters 1.6 to 10 m
3
/h (except for G¾Bx110 and G1Bx110) can be itted with a
strainer (ilter) and/or nonreturn valve (backlow preventer). The enclosed special polyethylene
gaskets
must
be used.
Strainer, nonreturn valve and special gaskets must only be used in cold water meters.
1.1 Permissible operating conditions / measuring range
Temperature of medium in low sensor:
Cold water meter: 0.1...50 °C
Hot water meter: 0.1...90 °C
Pressure stage:
Threaded meters PN16
Flange meters PN25
Mechanical environment:
M1 (MID). Fixed installation with minimum vibra-
tion.
Electromagnetic environment:
E1 (MID). Housing and light industry.
The meter’s control cable must be drawn at
min. 25 cm distance from other installations.
Climatic environment:
5 °C...55 °C.
Must be installed indoors and in environments
with non-condensing humidity.
MID = Measuring Instrument Directive 2004/22/EC.
2 Installation
In order to prevent cavitation the back pressure in the low sensor must be minimum 1.5 bar at Q
3
and minimum 2.5 bar at Q
4
(resizes of Q
3
and Q
4
, see label on low sensor).
The meter must not be exposed to lower pressure than the ambient pressure (vacuum).
Pressure stages are PN16 for threaded meters and PN25 for lange meters, see marking. Flow
sensor marking does not cover included accessories.
Straight inlets or outlets are not required in order to comply with MID. A straight inlet section will
only be necessary in case of heavy low disturbances before the meter.
