How to read McCrometer Flow Meters
A person reading a totalizer must be careful to add the correct amount of zeroes or place the decimal point in the right place. If a mistake is made, the meter reading can be off by a factor of 10, 100, or even 1000 units.
Most totalizers have “multipliers”. Multipliers are always a multiple or fraction of ten which are used to multiply the direct reading of the totalizer
Gallons: A meter that totalizes in gallons will have a multiplier of times 10, times 100, or higher. That means that the meter is read not as gallons, but as tens of gallons or hundreds of gallons. In the example to the left, the correct reading is 9,254,500 gallons.
Acre Feet: A meter that totalizes in acre feet will have a multiplier of times .01, times .001, times .0001, or smaller. The digit counters on the right side are colored yellow to indicate where a decimal point should be placed when reading the totalizer. In the example to the left, the correct reading is 92.545 acre feet.
