Divide the error by the true value:0.02/2.70 = 0.0074074. 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. The first step is to calculate K-factors to cover each flow range. Home Flow Measurement Solutions What is Flow Meter K-factor? K-Factor. Calibration is the process in which we minimize the error in the measuring device using a calibrator or prover. The vortex K-Factor is the proportionality constant that is used to relate the measured frequency to a volumetric flow rate. In practice, it is difficult to determine path length to the required accuracy. The industry-accepted formula for assay on anhydrous basis = (assay on as-is basis100)/(100-%water). A calibration curve is an empirical equation that relates the response of a specific instrument to the concentration of a specific analyte in a specific sample matrix (the chemical background of the sample). Guide to the Expression of Uncertainty in Measurement (GUM). By default S3D will wait for the bed to heat first, then begin heating the extruder; a waste of time! Compressor oil. And how to calculate? Your email address will not be published. All pulse output type flow meters when they are dispatched by their manufacturer will have a calibration certificate.
