A pressure gauge allows a fluid to enter from the item or equipment being measured and reacts by moving a calibrated rod inside it. The pressure can be correctly read when the rod has moved to its maximum position.

Gauge, when applied to sheet metal, is used to determine the thickness of a single piece of sheet metal, with lower numerical values indicative of increasing levels of thickness. There are a number of standard gauge measurements in use, each with slightly different standard thickness.

Size six ear gauges are considered to be larger than average. Most earlobes are initially pierced with an 18- or 20-gauge needle. Gauge sizes typically range between size 20 and 00, with 00 being the largest.

A diamond gauge measures the width, length and depth in millimeters of a diamond or other gemstone. More advanced diamond gauges also give the user an accurate carat weight for the stone. Others require the use of a conversion method to determine carat weight.

Typical earrings are gauged at either 18 or 20, depending on the particular piece of jewelry. Although gauge sizes can be as small as 00, 18 and 20 are the most common for new piercings so that a large amount of flesh is not removed from the lobe at once.

Regular earrings are generally 20 gauge, which is 0.0320 inches or 0.812 millimeters in diameter. The needle that does the actual piercing is typically a 14 gauge. In body jewelry, the larger the gauge, the smaller the diameter. Earrings worn on the cartilage of the ear are commonly 16 gauge.

G-gauge trains are large, durable models that are suited to an outdoor setting, such as a backyard or garden. The trains, their tracks and their accessories are designed to endure bright sunlight and inclement weather.

The zero error of a micrometer screw gauge occurs when the flat end of the screw touches the stud or anvil, and the gauge reads other than zero. If there is an error, it results in a positive or negative calculation. However, well-calibrated micrometers that are in good condition measure close to ze

Fuel gauge problems are commonly the result of faulty electrical grounding at the tank or a problem with the sending unit inside the tank but can also be caused by faulty wiring or a bad fuse. Troubleshooting the problem involves a process of elimination that includes each of these as a possible roo
