Standard meters: These measure the number of units of energy you use every hour and display readings on a simple, mechanical display.

Visible light is known to have wavelengths in the range of 400 to 700 nanometres (nm), or 4.00 × 10⁻⁷ to 7.00 × 10⁻⁷ m, which is between infrared which has longer wavelengths and ultraviolet which has shorter wavelengths. The wavelength of visible light implies it has a frequency of roughly 430 to 750 terahertz (THz).

Assertion : Now a days a standard metre is defined as in terms of the wavelength of light. Reason : Light has no relation with length. The moon is observed from two diametrically opposite points A and B on earth. The angle θ substended at the moon by the two directions of observation is 1∘54′.

If you have electric hot water at your property then it’s very likely that the second meter is in place to measure the electricity consumption for your hot water system which will run on a timer.

If the meter stops, turn on 1 appliance at a time and check the meter. If the meter starts to move very quickly, the appliance could be faulty. If the meter is still moving, it’s probably faulty.

While electric meters can last for decades, especially the mechanical ones, old meters can become inaccurate over time.

Myth: Unplugging your devices saves power and improves safety. Fact: Safety, maybe. But it won’t save much money these days. As it turns out, there is some validity to their argument, but there have also been recent technological breakthroughs that poke a hole in their defense.

Once you’ve located your water meter, turn off all water usage in your home, and then check to see if the dial is moving. If the water in your home is not being used, the dial on your water meter should not move. If the dial is moving, you’ve either got a leak or you’ve got a broken water meter.

The most common cause for a high water bill is running water from your toilet. This can cause a terrible increase to a family’s typical water use, so fix toilet leaks as soon as possible. Some leaks are easy to find, such as a dripping faucet or running toilet. You can usually hear a running toilet, but not always.

The size of your property can have a big influence on the cost of your monthly bills, including your water one. If you don’t have a meter, the more people who live in a house, generally, the more water that will be used. This is because of the people in it, using the water rather than the amount of rooms.

On the meter face there are two sets of numbers, black on the left and red on the right. The black numbers show the number of cubic metres used, while the red ones and the dials show litres. When submitting a meter reading, only read the black numbers and ignore the red numbers (one cubic metre = 1,000 litres).

To calculate your water usage, subtract the (P) previous meter reading from the (C) current meter reading. In the Meter Example, the water consumption was 3 hundred cubic feet. (Meter Example: 900-897=3)Click here to see what your water usage means in dollars and cents.

You’ll usually find your water meter under the kitchen sink where your water supply comes into your home. It could also be in an underground box in the garden, or the footpath outside your property (look for a small round plastic lid).

The most common cause for a high water bill is running water from your toilet. A continuously running toilet can waste up to 200 gallons a day. That can double a familyss typical water use, so fix toilet leaks as soon as possible. You can usually hear a running toilet, but not always.

Small leaks can mean increases in utility bills Also, if you have a leaking showerhead or pipe from your water heater, you may be running your electricity bill up too!

What this means is that energy-efficient toilets increase the velocity of the water when you flush and only use about 1.28 GPF (gallons per flush) as compared to older toilets that can use between 1.6 and 7 GPF.
