digital gas meter with temperature compensation

The digital gas meter is popular in Russia and other USSR(cccp) beacuse of its high capability/price ratio and small body.

Gas meter is used in household, has an LCD display.

Working temperature: -10C to 50C

Air moisture is lower than 95%,  temperature is lower than 35°CAtmospheric pressure is 84-106,7kPa (630-800mm mercury)Maximum working pressure is not more than 5.0 kPa (0.05 kg/cm2)Nominal diameter of T-pipe – 15mmOn the T-pipe there is thread G 1/2 for installationGas measuring range: from Qmin=0.04m3/hour, up to Qmax=1,6m3/hourRelative accuracy range:

Qmin-0,2Qmax   =   ±3.0%

0.2Qmax-Qmax for grade of accuracy 1,5 =   ±1.5%

Used for:

Natural gas (pressure not more than 5,0kPa)

Liquified gas (pressure not more than 5,0kPa)

Smallest scale division - 0.001m3Measuring device capacity - not less than 99999.999m3For gas meter a lithium battery is used (ER14505 size AA 3.6 V or CR2477 3 V),There is a model of gas meter with temperature correction, which has a temperature sensor, measuring gas temperature from -10C to 50CWorking period – 12 years from the date of productionWeight – not more than 0,67kgDimensions of gas meter not more than 70x77x76mmNon-ferrous metals, not more than:

Aluminium and its alloys – 0.10kg

Zink and its alloys – 0.45kg

Min flow (Qmin), m3/hour = 0.04

Max flow (Qmin), m3/hour = 1.6
