Calculating Your Energy Consumption

Styles of Meters

Mechanical Meter:

The rotating disk in the meter drives the mechanical dials. Actual consumption is measured by reading the four or five dials on the meter.

Hybrid Meter:

The rotating disk in this meter is connected to an electronic circuit board that calculates energy and demand. The readings are displayed on the digital LCD display.

Electronic Meter:

These meters are fully electronic. Actual consumption is measured by reading the number shown directly on the digital LCD display.

Electronic Receiver/Transmitter (ERT):

The ERT meters have a low-powered radio device that permits them to be read from a distance. This allows meter readings to be collected electronically with a mobile data collector (usually a laptop computer) or with a handheld Itron receiver.

Note that ERT can be applied to any of these meter type.

How to Read Your Meter

Read the meter by noting the position of the pointer on each dial, from right to left across the dials, and record the numbers in the same order. This is the proper way to read a meter Right to Left. If the pointer is between two numbers, record the smaller number except if it is between 9 and 0, in this case the reading is 9. Note the direction of rotation of the pointer clockwise or counterclockwise to ensure you record the smaller number. On electronic meters with digital display, the reading is shown directly on the display.

The reading is shown directly on the display: 15961

Regardless of the type of meter, the kilowatt-hours (KWh) you consume are registered cumulatively. To calculate your consumption, you must take the reading obtained (15961) and subtract from it the previous reading (which can be found on your latest invoice) then multiply the difference by the billing multiplier (when applicable can be found on your bill).

The number by which a demand reading is multiplied, to obtain actual usage data.
