Nonintrusive load monitoring (NILM), nonintrusive appliance load monitoring (NIALM), [1] or energy disaggregation [2] is a process for analyzing changes in the voltage and current going into a house and deducing what appliances are used in the house as well as their individual energy consumption.
The FLW 100 has a maximum gun depression of –15° and a maximum elevation of +75°. It can be armed with a single 5.56 mm or 7.62 mm machine gun and is intended for combat ranges up to 1,000 metres (3,300 ft). [3] The optronics of the FLW 100 are located in a container mounted behind the ammo box, located left of the gun.
A magnetic flow meter (mag meter, electromagnetic flow meter) is a transducer that measures fluid flow by the voltage induced across the liquid by its flow through a magnetic field. A magnetic field is applied to the metering tube, which results in a potential difference proportional to the flow velocity perpendicular to the flux lines.
Septuple meter can also be notated by using regularly alternating bars of triple and duple or quadruple meters, for example 4 4 + 3 4, or 6 8 + 6 8 + 9 8, or through the use of compound meters, in which two or three numerals take the place of the expected numerator 7, for example, 2 + 2 + 3 8, or 5 + 2 8.

Because they are used for domestic water measurement, piston meters, also known as rotary piston or semi-positive displacement meters, are the most common flow measurement devices in the UK and are used for almost all meter sizes up to and including 40 mm (1 + 1 ⁄ 2 in). The piston meter operates on the principle of a piston rotating within a ...
Schematic view of a flow sensor. An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. Using ultrasonic transducers, the flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound propagating into and ...
Before submetering, many landlords either included the utility cost in the bulk price of the rent or lease, or divided the utility usage among the tenants in some way such as equally, by square footage via allocation methods often called RUBS (Ratio Utility Billing System) or some other means. Without a meter to measure individual usage, there ...
The majority of manufacturers of electricity meters have radio frequency devices in the frequency band of 433/868 MHz for large scale deployment in European countries. The frequency band of 2.4 GHz can be now used in India for outdoor as well as indoor applications, but few manufacturers have shown products within this frequency band.
