Gas meters Grand TK(M)

Grand TK(M) gas meters are used for measuring the volume of natural gas or liquefied gas vapours, electronic correction of consumed gas volume by temperature of the measured medium. Maximum flow rate 4 m³/h.

Purpose:

Grand TK(M) gas meters are used for:

measuring the volume of natural gas or liquefied gas vapours;
electronic correction of consumed gas volume by temperature of the measured medium.

Field of application:

Metering of consumed gas:

in apartments;
in private houses;
in other utility and household facilities,

where the ambient temperature value can reach minus 30.

Can be installed:

in unheated premises;
outdoors in areas without direct entry of sunlight.

Features:

Can be installed in unheated premises or other areas where ambient temperature can reach minus 30;
The implemented degree of dust and moisture protection IP 65 ensures full protection from dust, condensate and protection from water jets, which allows instrument installation outdoors;
Electronic correction of gas volume by temperature of the measured medium. T-gas volume measurement at operating conditions and calculation of gas volumetric flow rate and gas volume normalized to standard conditions, with gas temperature measurement considering pressure parameters and gas-compressibility factor to be conditional-constant values;
Instrument's compactness is conditioned by the use of the jet method, which is particularly important during measurement of gas flow rate from 10 m³/h;
Absence of moving mechanical parts and, consequently, high reliability, conditioned by the chosen jet method of measurement;
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, also different gas flow directions are allowed (left, right);
Affordable price for clients, ensured by the advantage of the design as well as by the high efficiency of production processes arranged at the plant.
