Hydro Westmount
From the meter to your Hydro Westmount bill
Before being installed in your home, the meter has been inspected by Measurement Canada, just as gasoline pumps and commercial scales. The majority of meters are tested every 12 years (some every 6 years). Once calibrated, the meter is sealed to ensure that no one can tamper with its mechanism. The meter is a reliable, high-precision instrument that cannot be reset to zero after a reading. Should an error occur when your meter is read, the next reading will automatically correct it. Experience has shown that the meter is tough and hard-wearing.
- Your meter does not consume any electricity.
Four-dial electricity meter
Your meter keeps a running total of the kWh you consume, much like the odometer in your vehicle. It is equipped with a horizontal disk and four or five dials. The digits 0 to 9 appear on each dial.
- When you consume electricity, the disk rotates, driving a tiny sprocket wheel which in turn moves the pointer on the first, or units, dial.
- After one complete turn, the pointer on the units dial activates the dial on the second, or tens, dial.
- The hundreds and thousands dials are activated in the same way.
Your consumption is calculated on the basis of the readings on the four (or in some cases, five)dials.

Your meter has either four or five dials on it. Some hands move clockwise and others move counter clockwise. All hands move from 1 to 2 to 3, and so on. From left to right, read and record the placement of the hand on each dial. If the hand on the dial is between numbers, always use the lower of the two numbers. The only exception is if the hand is between 0 and 9, in which case you would use 9.
For most of our residential customers, meters are read six times per year and you will receive an invoice six times per year. You can budget accordingly by calling our Customer Service Office staff to determine the invoicing date for your area, or you can determine the schedule based on the invoice date of your first bill. Once you receive your first invoice, you will be invoiced at approximately the same time every two months.
If we have not been able to read your meter, we will estimate your consumption for that particular billing period. An estimated reading takes into account past electricity use as well as adjustments relating to the season. Any differences will be adjusted at the time of the next meter reading. Estimated readings only take place when we are unable to gain access to read your meter.
