Fig. 26. CKMT three-way valve
The valve handle position is secured by a seal. The valve may be operated only under
supervision of the gas company representative; after operation, the handle is again secured
with an installation seal.
The temperature measurement signal is received from the emitter installed in appropriate
temperature socket in the outflow section of pipework (downstream the gas meter) (Figs. 24
and 25) or in a temperature socket in the gas meter.
One should keep in mind that all activities associated with connection of any additional
equipment to the gas meter are also associated with removing the protection seals
and thus may be performed only by representatives of the gas company
or the manufacturer. Unused electrical output sockets must remain plugged with
factory-made plugs and installation seals.
