SG Statico

Why choose it

​Static measuring principle

The measurement is performed in static mode (without moving mechanical parts) and is expressed in m3 at basic conditions (standard m3) on the meter display.

The technology is based on a MEMS sensor which measures the temperature differential between two detection points and which is proportional to the gas flow that passes through them

The system maintains the accuracy of the measurement even in the presence of variations in the composition of the gases within the H and L groups, as defined by the EN437 standard; the measurement of some characteristics of these gases allows us to compensate for the effects due to the change in density.

Measurement principle also allows you to identify the presence of air inside the meter; this allows you to use air for its calibration and to generate an alarm if the phenomenon occurs after installation

The meters can work with biogas mixtures and with a maximum H2 percentage of 20%.
