You will need
- receipt of payment for services of gas supply, sent monthly;
- - the gas meter readings at the moment (end-index);
- - the gas meter readings at the time of payment for the previous month (the starting index);
- - rate this month for the gas supply.
Wait for a local organization that provides services for the supply of natural gas, will send you a receipt of payment. Some of the graphs in this payment document you will find blank - to make a payment, you will need to enter the appropriate values and make the calculation yourself. So let us turn to the actual count rate and the amount of gas that you spent in the current month.
Open the vandal-proof metal door of the gas meter (it is available on many models of this device) and look at the screen. You will see a series of numbers, the first five of which indicate an integer number of cubic meters of consumed gas (before the comma), then tenths, hundredths and thousandths. For a monthly payment for the supply of natural gas is necessary to fix five numbers, rounding the amount of consumed cubic meters of gas to as much as.
Take again the receipt of payment you find the column "final rate". This should fit you recorded the readings of the meter. In the column "initial rate" to enter the readings of the meter, which were final at the time of payment in the last month - you can see them in the same receipt ("last testimony of metering devices").
Subtract from the value of the final index value initial index and thereby obtain a gas flow rate for the current month. In accordance with this value and need to pay. To calculate the amount, see what the rate specified in the receipt - that's how much it will cost you one cubic meter of gas. Accordingly, multiplying this value by the already calculated consumption, you know how much you paid this month's gas and what amount you need to specify in the receipt before you will be able to pay utilities.
Before going to enter meter readings and the total amount of the receipt, check again the correctness of your calculations, for reliability use a calculator.
