How do you read a REV water meter?
Look at the numbers above each dial. The last one on the right says ‘1000’. But look CLOSER and you’ll see ‘per rev’ under that dial, meaning 1000 Cubic Feet PER FULL REVOLUTION. And if a full revolution is 1000 Cubic Feet, then each small increment with a number is 100 cubic feet.
What is the Kh of a meter?
Kh or Kh is referred to as the watt-hour constant and equals the number of watt-hours for one turn of a electromechanical meter, or one pulse period for electronic meters, like the WattNode® Pulse meter.
What is register ratio?
TRANSMISSION LINES DESIGN and ELECTRICAL ENGINEERING HUB Rr – Rr is the register ratio. This is the relationship between the first take off gear on the meter’s register and the far right hand dial on the front of the register. Rs – Rs represents the first shaft reduction.
How do you calculate meter reading?
Calculating your bill
- Current meter reading – Meter reading reported from last month’s bill = Total kWh used since last reading.
- Total kWh used since last reading x Charge per kWh = Total energy charge.
- Total energy charge + Fixed monthly fees = Final bill.
How is water measured?
Different utilities use different units for measuring water use. The most common units are centum cubic feet (CCF) and the gallon. A CCF also called an HCF (hundred cubic feet), represents one hundred cubic feet of water.
How do you read an old power meter?
The meter can be read from left to right, including all leading zeros. If a dial appears to be between numbers, record the lower number – except when the dial sits between 9 and 0, note down 9. If your meter has two readings marked with an L and H, please read both, left to right.

What is a 2 element meter?
Two-element wattmeters are generally used in delta connected systems. They require two line-line voltages and only two phase currents. Three-element wattmeters are used in wye connected systems. They require three line-neutral voltages and three phase currents.
What is a unit of water?
A unit of water is 100 cubic feet or approximately 748 gallons of water. If your bill states you used 3 units of water, you will have used approximately 2,244 gallons of water during the billing period (748 X 3 = 2244).
