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 ...
Electricity meter, a device for measuring electricity usage Smart meter, an electrical meter that records consumption of electric energy and communicates information to the utility for monitoring and billing; Gas meter, a specialized flow meter used to measure the volume of fuel gases such as natural gas and propane; Water meter, a device for ...
The power setting displays instantaneous power, and the kilowatt-hour setting displays energy consumed since last reset. When electricity is disconnected, the P4400's measurements and meters are reset. [6] To reset Kill A Watt models that store values, press Volt and Amp together, or press the Reset key in some models.
A submetering system typically includes a "master meter", which is owned by the utility supplying the water, electricity, or gas, with overall usage billed directly to the property owner. The property owner or manager then places their own private meters on individual tenant spaces to determine individual usage levels and bill each tenant for ...
M-Bus or Meter-Bus is a European standard (EN 13757-2 physical and link layer, EN 13757-3 application layer) for the remote reading of water, gas or electricity meters. M-Bus is also usable for other types of consumption meters, such as heating systems or water meters. The M-Bus interface is made for communication on two wires, making it cost ...
North American domestic analog (Ferraris disk) electricity meter. Electricity meter with transparent plastic case (Israel) An electricity meter, electric meter, electrical meter, energy meter, or kilowatt-hour meter is a device that measures the amount of electric energy consumed by a residence, a business, or an electrically powered device over a time interval.
Thus a meter with a 50 μA movement will have a "sensitivity" of 20,000 Ω/V. "Per volt" refers to the fact that the impedance the meter presents to the circuit under test will be 20,000 Ω multiplied by the full-scale voltage to which the meter is set. For example, if the meter is set to a range of 300 V full scale, the meter's impedance will ...
A 240/120 V split-phase service drop providing power to a residence in USA. The three wires from the utility pole enter through a weatherhead (top) into a vertical conduit, which routes them to the electric meter (bottom). From there they pass through the wall of the house to the electric panel and Main Fuses or Circuit Breakers inside.
