Odometer Type Index

The display on a meter can be read and compared to a previous reading to determine the amount of gas consumed over a time period. The digits displayed on an Imperial meter refer to 100's of cubic feet. A Metric meter displays cubic meters. The two dial indicators are for test purposes and are not considered for billing. Metric meters     can use test dials or more accurate odometer dials for presssure testing and clocking purposes. Examine [Reading 1] and [Reading 2] and calculate how much natural gas has been consumed between the two readings before clicking the [Answer].


Dial Type Index

The digits above each dial indicate how many cubic feet will have been used with a complete revolution of the respective dial. The 1/2 and 2 cubic ft dials are for test purposes and are not considered for billing. The test dials can clocked to calculate the amount of gas being used as well as to check for leaks. If there are no standing pilots in operation there should be no movement of the most sensitive test dial. Otherwise a leak is indicated which must be located and repaired. Note that adjacent dials rotate in opposite directions. Click [Reading 1]. The far left dial rotates CCW so it has passed the 6 digit. The next dial rotates CW and has just passed the 1 digit. Following this procedure the four dials yield the following digits: 6122 However, since this meter measures 100's of cubic feet we must multiply our reading by 100 which yields: 612,200 cubic feet. See if you can determine [Reading 2] before clicking [Answer]


Dial Accuracy

When the needle seems to be directly on a number, look at the dial to it's right. If the hand on that dial has passed 0, record the number the hand is pointing toward on the dial that you started with. If the hand on the dial to the right has not passed 0, record the smaller number on the dial that you started with. For an example click [Reading 1]. You now know whether to call the left digit a 5 or a 6. Determine the proper reading before clicking on [Answer].
