Installation; Fitting To A Diaphragm Gas Meter ≤ G25; Installations Made Directly Onto Thermowells - Elster TC210 Operating Manual And Installation Instructions

Temperature-Volume Corrector TC210

5 Installation

The installation and first test can occur without the presence of a calibration official, be-
cause all relevant areas are secured by adhesive labels.
5.1 Fitting to a diaphragm gas meter ≤ G25
According to the PTB directive TRG3, the TC210 can be put into operation together with
the commercial diaphragm gas meters BK-G10 to BK-G25 in the factory as a measure-
ment unit.

5.2 Installations made directly onto thermowells

In various versions the TC210 is set up directly on a thermowell.
If no thermowell is available, then with turbine-wheel and diaphragm gas meters the instal-
lation must be made up to 3 D (D = pipe diameter), but at most 600 mm after the meter.
With rotary piston meters the installation must be made up to 2 D in front of the meter.
F
A second thermowell for the comparison measurement is generally required
for acceptance of the system.
Version I Mounting directly on the thermowell using a plug system.
Version II Mounting on the thermowell using a plug system via a bendable arm.
Version III Mounting directly on the thermowell using a screw thread.
Version IV Mounting on the thermowell using a screw thread via a bendable arm.
