1. General information
Read this guide before installing the meter.
In case of incorrect mounting Kamstrup’s guarantee obligations no longer
apply.
MULTICAL®61 consists of a flow sensor and a calculator. The flow sensor electronics
are placed in the calculator’s connecting base, whereas the calculator top is a
display unit. The flow sensor is connected with the calculator by means of a 2.5 m
screened cable.
According to OIML R49 MULTICAL®61 can be described a ”complete meter”. In
practice this means that flow sensor and calculator must NOT be separated. If flow
sensor and calculator have been separated and the seals have thus been broken,
the water meter is no longer valid for billing purposes. Furthermore, the factory
guarantee no longer applies.
The accumulated water consumption, to be used for billing purposes, is displayed
in m3(cubic metres).
Various communication modules and power supplies can be added. The utility can
replace communication module and battery.
If greater distance is required (up to 10 m) between flow sensor and display unit, a
PULSE TRANSMITTER (type number 66-99-618) can be used.
See instructions 5512-587 for further information.
Small-size meters, 1.6 and 2.5 m3/h (except for G¾x110) can be fitted with a
strainer (filter)*. The enclosed special polyethylene gaskets must be used.
