Ammeter, Voltmeter, Frequency, Wattmeter, Energy Meter Symbol

Hey, in this article we are going to see the different types of electrical measuring instruments symbols such as Ammeter, Voltmeter  Frequency Meter, Wattmeter, Energy Meter, etc. Having a background in electrical engineering you must know these symbols. This type of symbol you can see in domestic and industrial installation diagrams.

Ammeter Symbol

Here you can see the symbol of ammeter.

An ammeter is a measuring instrument used to measure the electric current. When measuring the electric current the ammeter should be connected in series with the power supply and load. The symbol of the ammeter is drawn by a circle on the capital letter A.

Energy Meter Symbol

Here, you can see the symbol of energy meter.

An energy meter is an electrical measuring instrument used to measure electrical energy. The energy meter also has two coils - a current coil and a voltage coil. An energy meter also works almost the same as a wattmeter just the difference is it measures the electrical power per hour or a minute or second.
