SGB-1.8 gas meter G-Sh/white

Household gas meters SGB-1.8 are designed for measuring the volume of liquefied hydrocarbon gas in accordance with GOST 20448-90 and natural gas in accordance with GOST 5542-87 when accounting for gas consumption by individual consumers.

Gas flow measurement range (m3/h) - from 0.03 to 1.8.

The kit includes a nut thread 1/2 (nut-nipple)

Calibration interval - 12 years.

Check is fresh. Within 6 months.

Certificate of Conformity: Russian Federation and Republic of Belarus

Counter passport:
RF - YES
Republic of Belarus - NO

The principle of operation of household gas meters SGB-1.8 is based on the conversion of the volume of gas that has passed through the meter into a proportional number of electrical impulses using a jet oscillation generator, followed by counting on an electronic unit for measuring gas volume.
Counters consist of the following main units:
- a housing with a jet generator located in it, a piezoelectric element and inlet and inlet connecting pipes;
- electronic block;
- battery;
- two plastic pads.
Counters have a reporting device on a liquid crystal display.
