An electricity meter, ... Remote meter reading is a practical example of telemetry. It saves the cost of a human meter reader and the resulting mistakes, but it also ...
Automatic meter reading (AMR) is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices (gas, electric) and transferring that data to a central database for billing, troubleshooting, and analyzing. This technology mainly saves utility providers the expense of periodic ...
Capacitance meter: Measures the capacitance component Current clamp: Measures current without physical connection Curve tracer: Applies swept signals to a device and allows display of the response Cos Phi Meter: Measures the power factor Distortionmeter: Measures the distortion added to a circuit Electricity meter: Measures the amount of energy ...
The term smart meter often refers to an electricity meter, but it also may mean a device measuring natural gas, water or district heating consumption. [1] [2] More generally, a smart meter is an electronic device that records information such as consumption of electric energy, voltage levels, current, and power factor.
This standard defines a table structure for utility application data to be passed between an end device and a computer. The "end device" is typically an electricity meter, and the "computer" is typically a hand-held device carried by a meter reader, or a meter communication module which is part of an automatic meter reading system. C12.19 does ...

One natural application of narrow-band power-line communication is the control and telemetry of electrical equipment such as meters, switches, heaters and domestic appliances. A number of active developments are considering such applications from a systems point of view, such as demand side management . [ 12 ]
Auto-polarity for direct-current readings, shows if the electric polarity of applied voltage is positive (agrees with meter lead labels) or negative (opposite polarity to meter leads). Sample and hold, which will latch the most recent reading for examination after the instrument is removed from the circuit under test.
