SGD-3T Diaphragm gas meter with temperature compensator
The gas meter is equipped with a temperature compensator SGD-3T which performs correction of registration of the gas meter depending on the temperature of the gas within a range from – 40oC to +35 oС°.
The additional relative error of a gas meter caused by a deviation of a temperature of a gas being measured from normal temperature (20±3)oC should not exceed ±0,1 % in comparison with the basic relative error at temperature change by 1oC, and for a temperature above +35 oC - 0,45 %.
The gas meter is designated for operation at a temperature from – 40 oC to +50oC.
The pulse output device is embedded in gas meters of versions SGD-3T, SGD-3T-2I which allows to embed gas meters in the system of automated collection and processing of information.
