1. General
These instructions are intended for authorised specialist personnel. Basic work steps are therefore not included.
The seal of the energy meter must not be damaged! A damaged seal will automatically invalidate the
factory warranty and will require calibration of the meter. The supplied cables must not be shortened or
lengthened or modified in any other way.
Statutory requirements and operating regulations for the use of energy meters must be observed.
Installation may only be performed by an electrical company that specialises in energy meter installation.
Personnel must be trained in the installation and handling of energy meters and electrical devices, as well as the
applicable guidelines.
Medium: water, according to CEN/TR 16911.
When using water additives (e.g. corrosion protection), the user must ensure adequate corrosion resistance.
• The media temperature is specified as 5 ... 105°C (130°C)
• The temperature range depends on variants and nominal sizes.
• The exact temperature range is stated on the type plate.
• In the case of condensation, the sealed version should be selected.
• The operating/environmental conditions are specified as 5-55°C; IP 54/65; 93% rel. humidity.
• Ambient temperatures below 35°C are favourable of the service life of the battery.
If the flow sensor is insulated with the pipework, the counter must be exposed.
Reading and parameterisation is performed by the software program IZAR@MOBILE 2.
