Grand-4

‹ ›

Purpose:

Grand gas meters are used to measure the volume of: natural gas; liquefied gas vapours; other non-aggressive gases.

Field of application:

Grand gas meters allow for metering of consumed gas: in apartments; in private houses; in other utility and household facilities.

Features:

Instrument's compactness is conditioned by the use of the jet method, it ensures small overall dimensions of the instrument;
Absence of moving mechanical parts and high reliability due to this, also conditioned by the chosen jet method of gas consumption volume metering;
Simple mounting (gas welding operations not required) allows quick and inexpensive replacement of the old meter;
The meter can be mounted in any position convenient for the client, vertical or horizontal;
The manufacturer provides a long-term 12 year warranty.

Configuration:

By the colour of casing:

You can order the grand-4 from dealers at a good price.
