Jual Gas Diaphragm ITRON ACD G16
Spesifikasi Jual Gas Diaphragm ITRON ACD G16
Itron Diaphragm ACD G10-G16 meters combine accuracy and
long life in a very compact casing. Through our proven know-how in
gas measurement, combined with the use of modern engineering
and production techniques, Itron has developed this smaller size,
highly accurate meter, ensuring reduced shipping costs, and easier
handling and simplified installation. Our range of ACD G10-G16
meters are designed for commercial use for gas suppliers and gas
utilities worldwide.
Application
The ACD diaphragm meters are used for
applications requiring high precision and
large rangeability at low pressure (below 1
bar gauge).
They are supplied in two versions –
a compact and a standard version (single
and two pipe). Due to the volumetric
principle of the diaphragm meters, its
metrology is not influenced by installation
conditions.
They are designed for use with natural
gas, manufactured gas and other noncorrosive
gases.
The ACD diaphragm meters are approved
for fiscal use.
Operating Principle
The movement of the diaphragm is
caused by the pressure difference
between the inlet and the outlet of the
meter. The reciprocal filling is controlled
by means of two sliding valves.
This oscillating movement is transformed
into a rotational one and is mechanically
transmitted to the totalizer through a
magnetic coupling or a stuffing box.
