7.2 How to Read the kWh/Demand Meter
Fig. 17. KWh Reading
The Green Class kWh meter displays readings in whole numbers, there are no
decimals.
To find the dollar cost for the power used by the load(s) being monitored, you must first
find out what the cost per kWh is in your area (this cost can be found on your utility
electric bill, or call your local utility and ask for their cost per kilowatt hour.) Simply
multiply the cost per kWh by the kWh reading from the E-Mon D-Mon meter. The
resultant figure is the dollar cost for power used by the load(s) being monitored by this
meter.
Example:
8-digit display reading 00000017
Cost per kWh from utility $0.12100
17 x $0.121 = $2.06
Fig. 18. KW (Demand) Reading
The kW (Demand) reading is the peak usage over a specified time period (15 minute
standard, 30 minute optional). While kWh costs are interpreted as cents, Kilowatt costs
are usually represented in dollars, and interpretation of demand costs are based on
your utility’s tariff and rate structures. You will need to contact your utility to see how
your utility structures their kilowatt demand charges to ensure proper allocation of
costs utilizing data from the E-Mon D-Mon meter.
NOTE: THE FOLLOWING ONLY APPLIES TO METERS USING MORE THAN ONE
SET OF CURRENT SENSORS.
For meters using parallel current sensors you must multiply the kWh display reading by
the number of sets of current sensors installed. With Demand meters, the PEAK
Demand is also multiplied by the number of sets of current sensors installed.
Example:
17(meter display reading) x 2 (sets of sensors in parallel) = 34 kWh
34 kWh x $0.121 (utility cost per kWh) = $4.12
