These are devices that allow measurement of energy used by individual devices. There are a variety of models available on the market today, but they all work using the same basic principle. The meter is plugged into a power outlet and the device to be measured is plugged into the meter. These devices can help save energy by helping you know which appliances are using the most energy, or even if an appliance has a problem and is consuming more energy than it should.

Some of the new remote-controlled digital meters allow the connection of a device that transmits specific and periodic consumption to the user. With this information we seek to make the user aware of the energy they consume.

Meters can be manipulated so that they register less consumption than actual consumption, allowing the use of energy without having to pay for it. This theft of electrical fluid is a criminal offense according to different national legislations and, in addition, can be dangerous.[3]​[4]​[5]​.

The replacement of meters with new equipment with remote management is making it possible to detect many cases of theft of electrical fluid.[6]​.

When manipulation is detected, the marketing companies re-invoice the consumption not previously paid. The amount of this rebilling depends on each legislation, but if the unbilled amount cannot be determined, a payment formula of n hours of consumption, per contracted power, for a rebilling period of n months is applied. For example, in most US states for a price of $0.095/kWh the most common powered supply point would be charged $5000 per month.

Tampering with meters and other elements of the electrical supply can cause situations of physical danger to people and property,[7]​ by unprotecting elements of the connection. Fires occur in concentrations of meters, as well as surge spikes that can damage appliances or even injure people.
