Watt-hour meter

Turbine flowmeters are probably the most common example where pulse inputs are used. Another example is a watt-hour meter. Basically any measurement device that invowes a rotational element can be interfaced via pulses. 

Generator protection. The generator proteetive relays are mounted in a switehboard, whieh usually houses the wattmeter and various transdueers, teleduetors, and optional watt-hour meters. 

The early differential analyzers were very interesting. Vannevar Bush s first model was completely electrical, using a house-type watt-hour meter for... 

The PT is the transformer designed to provide the proper voltage to the measuring instruments such as voltmeters, frequency meters, wattmeters, watt-hour meters, etc, as well as protective devices such as relays, in which the secondary voltage is proportional to the primary and phase shift with respect to it an angle dose to zero. 

Power outlet. An enclosed assembly which may include receptacles, circuit breakers, fuse-holders, fused switches, buses and watt-hour meter mounting means intended to serve as a... 

The electrical consumption can be recorded using a Watt-hour meter. The energy consumption of microwave-assisted drying can be evaluated (Varith et al., 2007 Soysal et al., 2006) by two different efficiency indices, namely specific energy consumption (SEC) ... 

A typical loss and heat capacity calculation is indicated at the bottom of Fig. 5.4. The curve represents the adiabatic deviation, - Tg. In the initial isothermal period, the temperature change (drift) of the sample was followed with the platinum resistance thermometer as a function of time so that the initial drift, R, could be established, as is also shown in the analysis of heat loss of Fig. 5.3. The last temperature measurement of the sample before the heat addition, is T. The heater, monitored by the watt-hour meter,... 

The real power-kilowatt (kW) is the energy consumed by the load. Real power-kW is measured by a watt-hour meter and is billed at a given rate ( /kW-hr). It is the real power component that performs the useful work and is affected by motor efficiency. 

Thermal conductivity to convert watts per meter-kelvin to British thermal unit-feet per hour-square foot-degree Fahrenheit, multiply by 0.57779 and to convert British thermal unit-feet per hour-square foot-degree Fahrenheit to watts per meter-kelvin, multiply by 1.7307. Viscosity to convert pascal-seconds to centipoises, multiply by 1000. 

Light 50mg/10mL water Ambient Maximum 1.2 million lux hours and 200 watt hours/square meter, 6 hr, 1 day, 2 days... 

For the year 1955, 89,000,000 cubic meters of water were treated and 3,800,000 kw.-hr. of electrical energy were used, or 43 watt-hours per cubic meter. Thus average ozone dosage was 1.1 p.p.m. 

This completely automatic installation operates well, but seems much too expensive to run. The specific electrical consumption is 210 watt-hours per cubic meter of air, which brings the consumption for the ozonated air at a concentration of 10 grams per cubic meter, to 21 watt-hours per gram of ozone. This electrical consumption is much higher than that necessary for the production of ozone itself, and five to six times higher than that required for a drying system using activated alumina or silica gel. 

For confirmatory studies, samples should be exposed to light providing an overall illumination of not less than 1.2 million lux hours and an integrated near ultraviolet energy of not less than 200 watt hours/square meter to allow direct comparisons to be made between the drug substance and drug product.
