Grand SPI gas meter with a telemetry systemOur dealers
Grand SPI gas meters with telemetry systems are used for:
- measuring the volume of natural gas or liquefied gas vapours;
- electronic correction of consumed gas volume;
- remote data exchange with dispatching station.
Field of application:
Commercial metering of consumed gas:
- at utility and household facilities;
- at industrial facilities?
where the ambient temperature value can reach minus 30.
Can be installed:
in unheated premises;
outdoors in areas without direct entry of sunlight.Data recording and reports printing allow using the meters for metering gas consumption by legal entities.
Data transfer to a dispatcher station via a GPRS channel;
The meter can be incorporated into the automated gas metering system;
Full-range electronic temperature, pressure and gas composition correction;
Archiving and printout of archives of consumption, contingencies, events, gas composition; Ergonomics (substitutes 3 articles: meter, corrector, modem);
Can be installed outdoors;
By the colour of protective cover:
Based on overpressure limit:
- Maximum overpressure up to 5 kPa;
- Maximum overpressure up to 300 kPa.
Based on ambient temperature:
From minus 20°C to plus 60°C;
From minus 40°C to plus 60°C.
Based on reduction to standard conditions:
T-gas volume correction by the method T-conversion;
TP-gas volume correction by the method TP-recalculation;
TPz-gas volume correction by the method TPz-recalculation.
