GasMeter itron ACD G10

Pengukur gas ini memiliki empat ruang pengukuran yang dihubungkan bersama untuk membentuk unit yang dipisahkan oleh diafragma dan dinding yang dapat dideformasi.

Diafragma ini terhubung melalui piston yang berputar. Jumlah gas yang melewati diafragma meter dapat langsung diukur jika volume masing-masing ruang sudah diketahui.

Pengukur diafragma juga dapat digunakan dengan generator pulsa untuk menyediakan pembacaan meter. Namun, kebocoran dari bagian yang bergerak dan diafragma adalah penyebab utama kesalahan pengukuran saat menggunakan pengukur diafragma.

Diaphragm gas meter memiliki kelebihan :
1. Akurasi yang tinggi
2. Harga yang ekonomis
3. Masa pakai yang cukup panjang.


GasMeter itron ACD G10 Diaphragm Meters – High Accuracy Commercial Meters

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 easierhandling and simplified installation.
Our range of ACD G10-G16 meters are designed for commercial use for gas suppliers and gas utilities worldwide.

Application GasMeter itron ACD G10

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 GasMeter itron ACD G10

The movement of the diaphragm is caused by the pressure difference
between the inlet and the outlet of themeter. 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.
