User Manual Thermal Energy Meter Supercal 739
General
The compact mechanical single or multiple jet thermal energy meter Supercal 739 is a precision measuring instrument approved for individual metering of
heating systems and must be handled with care.
The Supercal 739 is available in a heating or cooling or heating/cooling version and determines the thermal and/or cold energy exchanged by a heat-
bearing fluid in a heat exchanger circuit.
The Supercal 739 complies with the requirements of the European Directive MID 2014/32/EU modules B and D and of the standard EN 1434 class 3.
Important!
The energy meter must be used within the conditions indicated on the meter; the metrological seals have to stay intact.
In the event non compliancy to these instructions, the manufacturer declines all liability, warranty and guarantee for correct metrology.
The manufacturer will not be liable in the event of any modification of the metrological data or of the measurement parameters if any of manufacturer's
seals is damaged. The seals can only be applied by authorised people in conformity to national legislation related to legal metrology.
Use only the accessories provided by the manufacturer.
For cleaning, a moist cloth is sufficient. Do not use solvents.
Do not shorten the cable between the flow meter and the integrator and the cables for the temperature sensors or modify them in any way whatsoever.
Before installation
Check the installation data and compare them with the specific characteristics of the thermal energy meter.
The rules for installation and those relating to the project must be respected.
The environmental temperature range for the energy meter is 5...55 ºC.
Make sure that the meter and the labels can be read easily.
All connections must be made at a minimum distance of 300 mm from high frequency or high voltage cables. Avoid thermal radiation and interfering electri-
cal fields near the integrator and connection cable.
As a rule, the integrator must be installed at a distance from pipes carrying refrigerating fluids.
Action must be taken to ensure that no condensation water can penetrate inside the integrator.
If there is any risk of vibrations, the integrator must be installed separately on the wall.
If the temperature of the fluid within the flow meter regularly reaches 90°C, the integrator must be installed separately from the flow meter.
It is advisable to drain the installation before fitting the flow meter. This will allow that any foreign body is withdrawn from the pipe.
Security with lithium batteries
3V lithium batteries are used. Certain security rules must be respected: the replacement of batteries or to add a second battery is not allowed.
During recycling, the following points must be respected:
Do not recharge or short-circuit, protect against humidity, do not expose to heat, do not throw batteries in fire, keep out of reach of children.
Advice on disposal:
In order to maintain and protect the environment, to reduce waste of natural resources and prevent pollution, the European Commis-
sion has established guidelines according to which manufactures must take back electrical and electronic devices in order to forward
them to a regulated disposal or recycling system.
If you dispose of the batteries yourself, enquire about the possibilities of recycling in your region.
Installation
The prescriptions related in the standard EN1434-6 must be respected when the Supercal 739 is installed.
In the standard version, the integrator is parameterised by default for installation on the "cold" pipe side. Installation on the "hot" pipe side must be specified
with the order.
Depending on version and use (heat and/or cooling meter), the energy meter must be fitted on the "cold" or "hot" pipe side of the installation in
compliance with the chosen configuration. If the device was ordered with the configuration option, some parameters can be changed using the
"Config" menu during commissioning.
In any particular installation, mixed mounting positions (horizontal and vertical) must be avoided because the measuring ranges are different.
Place the flow meter correctly according to the direction of the fluid (an arrow ➔ can be seen on the flow meter).
Horizontal mounting with the integrator facing downwards is not permitted. Also avoid fitting in a position which may cause an air bubble to build up inside
the mechanical meter.
The energy meter must be fitted between two shutoff valves. The flow meter must be installed ahead of any monitoring valves so as to avoid any potentially
interfering influence. Waterproof will be checked at the various mounting points.
The heat conveying liquid must be equivalent to water without any additives according to standard FW510 of the AGFW (German District Heat-
ing Association). If additives are added to the water, the user must ensure the compatibility of the materials used in the thermal energy meter which are in
contact with these additives.
