Diaphragm Gas Meters meet the highest demands with respect to
accuracy of measurement and safety. It incorporates both innovative
features and gas measurement know-how of many decades. These Gas Meters
are supplied in folded form as co-axial and two-pipe versions.

The
stroke of the diaphragms is pneumatically stopped and therefore ensures
both low bearing loads and a quiet operation. The synthetic diaphragm
is dimensionally stable and stadium shaped. High-grade materials and
components as well as the patented curve K-System ensure a high quality
standard. The K-System perfectly coordinates the movement of the valves
with the actual gas flow to the measuring chambers. This ensures
excellent linearity even with utilizing small valves. Due to the
optimized slides, Qmin these meters is stable and the gas meter is not
susceptible to contamination. The measuring unit is adjusted by a
patented needle-and-scale system. Although the design of the these Gas
Meters is very robust, the gas meters are still measuring instruments
and as such should be handled with care.
Operating principle: Four
measuring chambers are separated by synthetic diaphragms. The chambers
are filled and emptied periodically, and the movement of the diaphragms
is transferred via a gear to the crankshaft. This shaft moves the
valves, which control the gas flow. The rotations of the gear are
transferred via a magnetic coupling to the index.
