DESCRIPTION
General features0
The volumetric meter is used to measure the water flow that circulates in refrigeration and heating systems. Single jet water meters, from small to medium gages (flats, offices, shops, etc.) are particularly suitable in case of different variable flows during the day.
- Temperature up to 120°C (it resists up to 150°C).
- Nominal pressure: PN16.
- Protection degree: IP68.
- Dry clockwork with magnetic transmission.
- Rotatable register at 360° for an easier reading.
- High resistance components against wear and corrosion.
- Nonmagnetic capsule for protection against external influences.
- REED connecting cable (2 x 0,5 mm² x 1,5 m), not extendable, resistant up to 130°C.
- Impulse values rigidly confirming to MID directive.
- 10 litres/pulse.
- Standard measuring range with horizontal installation Qi/Qp 1:50.
- Standard measuring range with vertical installation Qi/Qp 1:25.
- Clockwork maximum reading: 99999 m³.
- Clockwork minimum reading: 00001 m³.

HOMOLOGATION AND INSTALLATION
Homologation
- Complies with the European Directive 2004/22/CE from the European Parliament related to measuring instruments (MID).
- Horizontal installation, B class.
- Accuracy 3 class.
Installation and use- The volumetric meter has to be installed on the system return pipe.
- Horizontal and vertical installation.
- The volumetric meter mechanical heart is the single jet turbine, whose number of revolutions is directly proportional to the circulating water flow. Every volumetric meter is provided with a pulse emitter and connecting cable to transmit the turbine revolution number remotely.
- Through a rotary magnet, the pulse emitter converts the mechanical movement into an electromagnetic contact (REED contact) that releases electrical impulses with a frequency proportional to the turbine revolution number and consequently to the circulating water flow.
- A dedicated electronic then acquires such signals along with those coming from the two temperature probes installed on the delivery and return system pipes, it processes them and calculates the used thermal energy.
- Having the dry clockwork, only the turbine operates in the wet room, preventing the damages caused by the water impurity.
