SGD4 Diaphragm Gas Meters are intended for measuring the amount of natural gas [GOST 5542-2014 Standard], vapours of liquefied hydrocarbon gas [STB 2262-2012 Standard], as well as other non-aggressive gases used for consumer or industrial purposes.
Application area: social, recreational and service facilities, residential buildings.
The Meter has 2 chambers which are separated by a gas-tight diaphragm. Due to the fact that gas pressure at the input and at the output of the Gas Meter is different, the diaphragm is moving and rotating the counter in the front panel.
Gas Meters are divided by the following criteria:
a) flow direction: left / right;
b) rated flow: G1.6; G2.5, G4 size
Pipe spacing: 110 mm
Cyclic volume: 1.2dm3/turn
Pipe thread: G11/4
c) availability of the compensator providing for correction of the register readings according to the gas temperature:
- without temperature compensator;
- T: temperature compensator.
d) availability of auxiliary devices:
- I: pulse output;
- R: wireless data transmission channel.
SGD4-x-x-X X I / SGD4-x-x-X X R modifications can be integrated into the unified system for automatic data collection and processing.
The Meter check period shall be selected by the checking organization. The Meter calibration period: 10 years
