As k=1 is not an acceptable standard for reporting uncertainty as it leaves a lot of room for passing erroneous readings. A homes k factor represents the number of gallons of fuel burned per degree day. In most countries, ISO/IEC 17025 is the standard for which most labs must hold accreditation in order to be deemed technically competent.

A calibration does this by matching your pH meter to the current characteristics of your pH sensor. The equation will be of the general form y = mx + b, where m is the slope and b is the y-intercept, such as y = 1.05x + 0.2. If the flow rate was given in units per hour the totalizer K-factor (for whole units) is obtained by multiplying the rate K-factor by 3600. For example if an instrument is to be calibrated to measure pressure in the range 0psig to 400psig, then LRV = 0 and the URV = 400psig. In vortex flowmeter, the relationship between flow rate and the number of vortexes generatedcan be expressed by the following formula. Variable area flow meters are flow meters in which the fluid must pass through a restricted area. The calibration certificate will show that the meter has been calibrated over its flow range and noted on the certificate will be the average K-factor for the meter. What Does k=2 Mean in Accuracy and Uncertainty Specifications? Meter K-Factor is defined as the number of pulses per unit mass or volume at a particular flow rate. (e.g.) What A Calibration Certificate Should Contain. It represents how many frequency signals per cube. The equation is as follows: C = Q / (change in temperature).

All pulse output type flow meters when they are dispatched by their manufacturer will have a calibration certificate. What is correction factor in calibration? What is K-factor in calibration?
