Grand SPI gas meter with telemetry system and shutoff valve
Our dealersPurpose:
Grand SPI gas meters with telemetry system and shutoff valve are used for:
- measuring the volume of natural gas or liquefied gas vapors;
- electronic correction of consumed gas volume; data receiving and transfer to a dispatcher station.
The meter is equipped with a shutoff valve, which allows full- scale Implementation of the safety subsystem, as well as remote control of gas supply to shut-off non-payers.
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 to use the meters for metering gas consumption by legal entities
Features:
-
The meter can be incorporated into the automated gas metering system;
-
Automatic gas supply shut-off in case of leak detection;
-
Monitoring of premise gas contamination, with the gas detector connected;
-
Data transfer to a dispatcher station via a GPRS channel;
-
Full-range electronic temperature, pressure and gas composition correction;
-
Archiving and printout of archives of consumption, contingencies, events, gas composition; Ergonomics (substitutes 4 articles: meter, corrector, modem, shutoff valve);
-
Can be installed outdoors;
-
Moderate price.
Configuration:
By the colour of protective cover:
-
White;
-
Gray;
- Orange.
Based on overpressure limit:
- Maximum overpressure up to 5 kPa;
-
Maximum overpressure up to З00 kPa.
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;
