April Fools' Day

April Fools' Day (sometimes called April Fool's Day or All Fools' Day) is celebrated every year on the first day of April as a day when people play practical jokes and hoaxes on each other. The jokes and their victims are known as "April fools". Hoax stories may be reported by the press and other media on this day and explained on subsequent days. Popular since the 19th century, the day is not a national holiday in any country, but it is well known in Canada, Europe, Australia, Brazil and the United States.

The earliest recorded association between 1 April and foolishness can be found in Chaucer's The Canterbury Tales (1392). Some writers suggest that the restoration of 1 January as New Year's Day in the 16th century was responsible for the creation of the holiday, but this theory does not explain earlier references.

Finally,happy April Fool's Day to everyone.^_^

Water metering

Water metering is the process of measuring water use.

In many developed countries water meters are used to measure the volume of water used by residential and commercial building that are supplied with water by a public water supply system. Water meters can also be used at the water source, well, or throughout a water system to determine flow through a particular portion of the system. In most of the world water meters measure flow in cubic metres (m³) or litres but in the USA and some other countries water meters are calibrated in cubic feet or US gallons on a mechanical or electronic register. Some electronic meter registers can display rate-of-flow in addition to total usage.

There are several types of water meters in common use. The choice depends on the flow measurement method, the type of end user, the required flow rates, and accuracy requirements.

In North America, standards for manufacturing water meters are set by the American Water Works Association.

Electricity meter

    An electricity meter, electric meter, or energy meter is a device that measures the amount of electric energy consumed by a residence, business, or an electrically powered device.

    Electric utilities use electric meters installed at customers premises to measure electric energy delivered to their customers for billing purposes. They are typically calibrated in billing units, the most common one being the kilowatt hour. They are usually read once each billing period.

    In settings when energy savings during certain periods are desired, meters may measure demand, the maximum use of power in some interval. "Time of day" metering allows electric rates to be changed during a day, to record usage during peak high-cost periods and off-peak, lower-cost, periods. Also, in some areas meters have relays for demand response load shedding during peak load periods.
