Duratec Gas Meter Tipe G4

Diaphragm Meters / diafragma gas meter

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.

The diaphragm gas meter is to use the differential pressure principle between inlet and outlet to impulse the diaphragms in the diaphragm boxes to do the to-and-fro movement. When the gas flow rate enters into the meter, it first is full of the space inside of the meter housings, from the rotary valve mouths due to the differential pressure, the gas will alternately enter into the different diaphragm boxes and realize the diaphragm boxes alternately charge and discharge. The movement of the rotary valve is transferred to the driving gear via the transmission mechanism and accumulates, the gas volume through the meter to index counter
by the ratio calibration gears to realize the metrology of the gas meter. With designing of independent measuring unit structure and high quality die cast aluminum-alloy case, the product has accuracy and reliability measurement under high operation pressure. Designing and producing meticulously, test strictly for GA serials gas
meter which suitable for NG, LPG, Town gas, marsh gas measuring.Features :
