Probably a regular energy meter that is meant for you to use in your house.
Simple example for integrating instrument is energy meter that is used in houses which indicates the summation of readings(units) consumed...
Solar panels and heaters are used. They trap sun's energy.
by adding the objects kinetic energy and potential energy
Anaerobic.
An electric meter or energy meter is used now a days.
Energy meters typically use mechanical damping, such as a moving disc or pointer attached to a coil, to slow down the movement of the measuring mechanism and ensure accurate readings. This damping helps prevent the energy meter from overshooting or oscillating during sudden changes in load.
The energy meter constant is a value that is used to convert the reading from the energy meter (in watt-hours) to the actual energy consumption of a device or system. It is typically a fixed value that is specific to the energy meter being used and is determined during the calibration process.

Voltmeter
Won't it be the Wattmeter, for 1W = 1Joule/second? The domestic electricity meter is a kW/hr meter.
In a distortion factor meter the filter at the front end is used to suppress which type of hormonics
Some houses yes, they used a type of river mud that was like plaster after it dried.
