The Gallus 2000 uses the positive
displacement diaphragm principle.
Its design consists of a twin-chamber
diaphragm-measuring unit. The twin
chambers are each fitted with a
flexible and gastight diaphragm which
move by the differential inlet and
outlet pressure. A transmission
system with a rotating mono-valve,
and a valve system, transfer the
reciprocating motion, driving the
mechanical retrofittable index.
The whole measuring system is
contained in a robust gastight casing.
The construction and the operation
design of this meter make the Gallus
2000 an extremely reliable and
accurate product.
