Pre-Paid Gas Meter
Domestic Pre-Paid Diaphragm Meter
Pre-Paid G1.6s Meter
The diaphragm meter works on the positive displacement principle wherein the volume received in inlet side is discharged to the outlet side. Thus, making the measurement fully reliable. Further, the diaphragm gas meter works on the diﬀerential pressure between inlet and outlet to impulse the diaphragms in the diaphragm boxes. When the gas enters into the meter, it ﬁrst ﬁlls the space inside the inlet meter housing from the rotary valve mouth.
Due to the diﬀerential pressure, the gas will alternately enter into the diﬀerent outlet chamber, alternate charge and discharge will continue till the gas is consumed. 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 steel case, the product has accuracy and reliability measurement under operation pressure. Designing and producing meticulously, test strictly for GA serials gas meter which suitable for NG, LPG, Town gas, marsh gas measuring.
The System, provides an energy supplier with the facility to receive payment for the gas before it is used. The solution differs from the standard AMR offering. A solenoid valve fitted on the inlet to the meter, and the meter module has a display. It permits gas to flow when there is credit, and shuts the valve when there is not. Each meter is linked with a Token. The token is for the customer applying credit to the meter.
The card can be “topped up” at the registered charge points where money is exchanged for a volume of gas. The amount of gas is loaded onto the card. The card is then swiped across the pre-paid meter and the credit is transferred. The display on the Wave module provides real time data showing the credit balance, the emergency credit available, valve status, and an indication of active alarms.
