User guide

1 - DELIVERY AXONIC
• Check completeness before installation
• 1 flow meter incl. connecting cable (l = 3 m or 10 m)
• Moving flanges. (PN16 and PN25 versions only)
• 1 set of gaskets
• 1 mounting and operation instructions
• Calibration Report and CE-Declaration (depending on country)
2 - GENERAL INDICATIONS
Flow meter AXONIC is a sophisticated electronic measuring instrument for measurement of thermal energy in either hori-
zontal or vertical position. Axonic can be connected to any calculator with compatible signal-input. The following instructions
must be carefully observed in order to ensure correct mounting and to fulfill all safety and guarantee conditions.
2.1 - Advise concerning safety
Hot water circuits and mains power supplies run under high temperatures and pressure as well as under high voltages.
When operated incorrectly, these may cause serious injuries. Due to this, measuring units may only be installed by qualified
and trained personnel. Prior to any installation / de-installation of Axonic it is mandatory to close and empty the concerned
network section. The casings of the heat meters are designed for cold, warm and hot water, with the characteristic values
specified for each case, excluding any other liquid. If the flow meter casing is submitted to strong shocks, impacts, drops
from more than 60 cm height or similar stresses, the heat meter must be replaced. Pipes must be earthed.
The complete system or global installation which will use this equipment must be protected by valve or a pressure limiting
system in order to respect the maximal pressure of the equipment.
2.2 - CE marks and protective classes
Metering unit AXONIC fulfills all requirements of applicable EC guidelines, and is approved in environmental class C (Indus-
trial applications), according to DIN EN 1434, MID environmental class E2 and M2 (MID 2014/32/EU):
• Ambient temperature: -25°C ... +60°C (indoors installation)
• Storage temperature:
- Permanent: T°MIN = -25°C T°MAX = 60°C
- Max +70°C (< 24 hours continuous)
• Flow sensor IP 68 (7 days under 1.2 meter of water at ambient)
• Axonic is conform to DIRECTIVE 2014/68/EU (Heat version only), fluid group 2 (Approved for water only).
• Discarded electronic devices contained within must not be put in normal house hold waste. Dispose in accordance to local
government regulations.
• The metrological class of a complete thermal energy meter, made of subassemblies (flow meter, calculator and temperature
sensors pair), assembled and installed according to the manufacturers installations instructions, meets the metrological class
that is indicated on the flow meter type plate.
• Cooling meter versions meet the requirements of MessEV.
2.3 - Further important indications
• The flow meter must never be lifted or carried by its connecting cable.
• Mounting position shall be selected so that the connecting cable of the flow meter and the temperature probe cables will not
be near mains cables or other sources of electromagnetic disturbances (minimum distance 50 cm).
• Cables must not be installed along pipes reaching temperatures above 60 °C.
• Opening of calibration seals will cause the loss of calibration validation and of guarantee.
• Unsealing the device is excluding the guarantee of conformity to directive PED 2014/68/EU. (Heat version only)
• The casing may only be cleaned on the outside, with a soft, damp cloth. Do not use detergents.
• Installation must be carried out according to EN 1434.
• There may be local rules that must be followed but not covered with this manual. Please check with the experts of the country
in which the meter will be installed.
• In Bi-Functional applications, the durability of the flow sensor is limited to 5 years.
