A femtosecond is the SI unit of time equal to 10-15 or 1⁄1 000 000 000 000 000 of a second; that is, one quadrillionth, or one millionth of one billionth, of a second. Its symbol is fs. A femtosecond is equal to 1000 attoseconds, or 1/1000 picosecond.
The acronym “FS” is used to represent the phrase “for sure.” The phrase is used to express confidence in something or someone. Origin of FS. The phrase “for sure” was derived from the word “sure.” This word, with its roots in French, has always been defined to mean that someone was certain.
FS means "For Sale" or "F***s Sake"
Full Scale (F.S.)"Full scale" indicates the full scope of the measurement range. For example, full scale for a Sensor with a measurement range of ±10 mm is 20 mm.
Since binary integer representation range is asymmetrical, full scale is defined using the maximum positive value that can be represented. For example, 16-bit PCM audio is centered on the value 0, and can contain values from −32,768 to +32,767. A signal is at full-scale if it reaches from −32,767 to +32,767.
Accuracy of reading means the percentage of variation will remain a constant percentage over the full range of flow. Accuracy of full scale means the percentage of variation is fully dependent on the maximum flow rate of the device and the variation will be a constant flow rate (ie: gpm) as opposed to a percentage.
Accuracy as a percent of span means that a 100 psi gauge with a 2% accuracy is accurate to within 2 psi whether the gauge is reading 1 psi or 100 psi. For example, a 100 psi gauge with Grade A accuracy is accurate to 2% of span from 0 to 25 psi and 76 to 100 psi while being accurate to 1% of span from 26 to 75 psi.
The error is calculated by determining the difference between the actual output measured and the ideal output for a particular input value.
Accuracy refers to how closely the measured value of a quantity corresponds to its “true” value. Precision expresses the degree of reproducibility or agreement between repeated measurements. The more measurements you make and the better the precision, the smaller the error will be.
General-purpose analog voltmeters may have an accuracy of a few percent of full scale and are used with voltages from a fraction of a volt to several thousand volts. Digital meters can be made with high accuracy, typically better than 1%.
By definition, percentage is a fraction or ratio expressed as part of 100. To determine the pages read percentage, divide the pages read of the book by the number of pages in the book.
To properly select a pressure gauge, consider the gauge process, range, environment, accuracy, dial size, connection and mounting requirements. Environmental considerations include ambient temperature, air-borne particulate, condensation, humidity, water and chemicals, all of which can affect gauge performance.

In industrial instrumentation, accuracy is the measurement tolerance, or transmission of the instrument and defines the limits of the errors made when the instrument is used in normal operating conditions. the difference between the mean of the measurements and the reference value, the bias.
The ball type of flowmeter has a ±5% accuracy rating, and the rotameter has a ±2% accuracy rating.
Flow meter accuracy is how close the measurement is to the true value. In flow meters, that means how close the output of the meter is to its calibration curve. This is expressed as a percentage, e.g. ±1%. It means that any given reading can be in error 1% above or below the calibration curve.
to know the accuracy. The accuracy of a flow meter can be stated one of two ways; as a percentage of full scale (FS) or as a percentage of reading (RD, also referred to as per- centage of rate). It is important to understand the meaning of both so that your flow meter performs as expected and with the desired accuracy.
The hysteresis error of a pressure sensor is the maximum difference in output at any measurement value within the sensor's specified range when approaching the point first with increasing and then with decreasing pressure.
In the science of measuring things, "accuracy" refers to the difference between a measurement taken by a measuring tool and an actual value. The relative accuracy of a measurement can be expressed as a percentage; you might say that a thermometer is 98 percent accurate, or that it is accurate within 2 percent.
Accuracy = closeness of agreement between a measured quantity value and a true quantity value of a measurand. Error or measurement error = measured quantity value minus a reference quantity value.
For pressure gauges with a pointer stop, the accuracy class applies from 10 to 100 % of the scale range. For pressure gauges with a free zero point, the accuracy class applies from 0 to 100 % of the scale range.

Accuracy. The accuracy of the sensor is the maximum difference that will exist between the actual value (which must be measured by a primary or good secondary standard) and the indicated value at the output of the sensor. Again, the accuracy can be expressed either as a percentage of full scale or in absolute terms.
Sensor drift is a common problem that can lead to inaccurate temperature measurement readings. It can be caused by several factors including environmental contamination, vibration or extreme temperature fluctuations.
For all 100 disposable pressure transducers, the average output was 100.03 +/- 0.55 mm Hg, with the worst cases being 98.53 and 101.36 when 100 mm Hg was applied. Even the worst case transducers were twice as accurate as required by the American National Standards Institute standard.
