How do On Demand Meters work?

Demand is the average amount of power (kilowatts) measured over a 15 minute period. Demand meters constantly recalculate the 15 minute average and the highest average is recorded and displayed on the meter. A business might use an average 25 kilowatt hours of electricity an hour (kWh), but occasionally a piece of equipment may be fired up that uses 40 kilowatt hours an hour. The demand meter measures that surge, and a demand fee is charged to customers to ensure that the 40 kilowatt hours of electricity will be there when the business owner needs it.

Demand meters can be purchased from any major electrical components manufacturer ie. GE, Siemens, ITRON.
Why does my new electronic unit continue to blink from 00008 to 88888?

The 88888's occur every 5 seconds or so while the meters does an internal check to make sure everything is working properly. The 00008 is the current reading. Based on your consumption history, you will use/add 1 to 3 kw/h every hour. The display will now likely be somewhere in the range of 00025 to 00050 depending on your usage overnight. You can take a reading anytime you like and subtract the previous reading to see how many kw/h you have used since the previous reading.

Meter Reading
Wade, Meter Reader, reading a dial meter at a residential home.
Every time you flip a switch, use an electrical appliance or start an electric motor, the electric meter measures how much electricity is used.

The meter is like the odometer on your car. By reading the odometer at regular intervals and subtracting the beginning reading from the ending reading, you can determine the distance travelled over a certain periods. Your electrical meter operates the same way. To calculate how much electricity you have used, subtract the earlier reading from the current reading.








Radio Interrogated (RI) Meters

Maritime Electric is in the process of replacing residential dial read watt hour meters with new Radio Interrogated meters. A Radio Interrogated meter is a solid state single phase meter with an easy to read digital display. The meter transmits a signal to a hand-held meter reading device carried by our personnel. This device reads the meter electronically then the data is downloaded to a computerized billing system. There are several advantages to this new technology in that the customer can easily read their own meter to monitor daily or weekly consumption patterns and the customer is issued a monthly bill based on actual readings, not estimated usage. It is anticipated that all residential customers will be metered with Radio Interrogated technology by 2013.

Dial Meters

A Dial Meter is an electromechanical meter that operates proportional to the power being used. This type of meter has a revolving disk and a series of dials and pointers. The more electricity being used, the faster the revolving disk moves. Each complete revolution of the disk measures a precise amount of electricity. This measurement is indicated by the position of the pointers on the dials. These dials and pointers on the electromechanical metering device records the amount of power used and a Maritime Electric Representative visits the meter bi-monthly to manually input the reading into a computerized device to be downloaded to the billing system.
