Excess reading in CNG gas metres
Tuesday, 10 June 2014
Most of the vehicles in the city run on compressed natural gas (CNG). I have been using a car for the last couple of years with CNG. The gas cylinder in my car is re-filled in full with maximum Tk 330 at 200-bar presser @ Tk 30 per cubic metre. In recent past, it required over Tk 420 to fill the cylinder in full. Neither the price of CNG has increased, nor has the cylinder been changed. Its capacity remains same as before. The cylinder used to be filled in full by maximum 11 cubic metres CNG but it takes even 14 cubic metres now. How it is possible?
I have every reason to believe that the measuring metres of the filling stations are showing excess reading. The metres need to be verified by an appropriate authority.
Surprisingly, the measuring metres did not show less reading than earlier readings in any CNG filling stations I visited recently. In all stations from where I took CNG recently showed higher reading. Probably deliberately, the measuring metres had been calibrated to show higher reading.
As a consumer, I would like to urge the authority concerned to verify all dispensers of the CNG re-filling stations.
