What An Electric Meter Measures

The disk is turned by the electricity passing through the meter giving a readout of how much electricity you are using.

What an electric meter measures.

Understand the parts of your analog meter also known as a dial meter and how it works. Electric utilities use electric meters installed at customers premises for billing and monitoring purposes. In the past all electricity meters were mechanical devices that a utility employee had to read manually. An electricity meter shows how much energy you ve used and will dictate how much you are charged on a monthly quarterly or annual basis so it s vital to understand how to take accurate measurements.

Current is the flow of electric charge through a conductor. Electrical usage is measured in kilowatt hours. Your electric meter usually has between four and six dials that advance as a central disk turns. One ma is one thousandth of an ampere.

Current is measured in units called amperes it should come as no surprise then that a meter that measures amperage is called an ammeter. Ammeters usually measure current in milliamperes also called a milliamp and abbreviated ma. The standard units of electrical measurement used for the expression of voltage current and resistance are the volt v ampere a and ohm ω respectively. Typically it is installed at the point where the power lines enter your building.

Electric utilities measure the electricity consumption of their customers with meters that are usually located on the outside of the customer s property where the power line enters the property. An electric meter is a device that measures the consumption of electricity used by your household as it passes into your home. An ammeter which measures current. Whatever form of meter you have it measures the amount of electricity you use in watts or more specifically kilowatt hours.

They are typically calibrated in billing units the most common one being the kilowatt. An electric meter or energy meter is a device that measures the amount of electric energy consumed by a building tenant space or electrically powered equipment. These electrical units of measurement are based on the international metric system also known as the si system with other commonly used electrical units being derived from si base units. One multimeter can take the place of a voltmeter which measures voltage.

While there are several meter types a multimeter is the most economical as it performs several functions in one unit. Like the mileage display in your car that shows you the total distance your car has traveled the electric meter displays the total. 1 volt x 1 amp 1 watt. And an ohmmeter which measures resistance.

Electric utilities use electric meters installed at customers premises to measure electric energy delivered to their customers for billing purposes.
