Description of the device
The CALOR 38 heat meter is based on measurement principle by a well-known Faraday's
electromagnetic induction law according to which an electric voltage is induced during the flow of a
conductive liquid through the flow meter magnetic field. This is sensed by two electrodes which have
direct contact with the measured medium and evaluated in the electronic unit, taking into account the
temperature difference of the paired resistance temperature sensors on the supply and return pipes.
CALOR 38 induction meters are suitable exclusively for measurement of volumetric flow of
electrically conductive liquid substances with a minimum conductivity of 20
S/cm (at a lower
conductivity, in agreement with the manufacturer).
Meters are designed for measurements where the velocity of liquid is in the range of 0.01 ÷ 12 m/s.
The best measurement accuracy can be obtained in the range of 1 ÷ 10 m/s.
Scope of delivery
The accessories vary according to flow sensor versions and above standard optional features.
Threaded construction
Electronic evaluation unit with the fixing bracket for wall mounting (not for the compact construction),
the flow sensor (in case of the compact construction, the electronic unit is an integral part of the
temperature sensor), paired resistance temperature sensors, connecting grounding cable, installation
manual.
Flanged construction
Electronic evaluation unit with the fixing adapter for wall mounting ( not for the compact construction),
flow sensor (in case of the compact construction, the electronic unit is an integral part of flow sensor),
paired resistance temperature sensors, connecting grounding cable, installation manual.
In case of the separated construction, a special cable for connection of the meter (it must not be
extended or cut short) is part of the flow sensor.
Storage conditions
The temperature during shipment and for storage must be within the range of -10 °C up to 50 °C.
Wooden boards installed on the flanges in the factory are used for protection of lining on the flanges
during storage and transportation (for PTFE lining). Remove these protective boards just before
installing in the pipeline!!!
Do not lift the flanged meters by the transducer head or by the connecting box of the separated
construction during transportation! Use slings and place them round both process connections for
transportation of meters up to DN150 (chains may damage the meter head)! Use only the holes between
the flange and sensor body for transportation, lifting and installation of the sensor in piping for DN200
and bigger!!!
