Use of devices that measure and register the amount and/or direction of energy quantities relative to time.
Measuring how much electricity a customer uses.
The process and methods of utilizing devices to measure the amount and direction of electrical energy flow, particularly for end-use.
A system to measure the amount of light in the frame to be able to calculate the best exposure mode.
Measures the amount of light when framing a photo and determines the best exposure. The main digital camera metering types are: Matrix (Evaluative), Spot and Center-weighted.
Instruments that measure electric voltage, current, power, etc.
Used to calculate the exposure from the existing light conditions. See: "Matrix Metering", "Spot Metering" and "Center-Weighted"
Measurement of water and electricity flow and consumption.
The process of measuring the available light reflected from the subject to calculate the proper shutter speed or aperture.
Controlled forward extrusion of molten feedstock past the screw tip and check ring to ensure the proper shot volume is ready for the next filling event.
measurement; as in 'the solvent was metered in at the rate of one gallon per hour'
The process of measuring the available light reflected from the subject to calculate the proper exposure time or aperture.
