What calibration means for your Flow Meter?
A calibration process involves correctly setting up the measuring instrument so that it enables accurate reading on the scale. In other words, the comparison of an instrument or a measuring device to a standard reference is known as Calibration. INTRODUCTION: A calibration process involves correctly setting up the measuring instrument so that it enables accurate reading on the scale. In other words, the comparison of an instrument or a measuring device to a standard reference is known as Calibration. So, in nutshell, the concept of calibration basically conveys that a measuring device ought to be tested initially and then adjusted so that it reads correctly. CALIBRATION VS. RECALIBRATION After the manufacturing process is over, flow meters like any other measuring device must first be calibrated before putting them out to use. Majority of the manufacturers own, self-calibration facilities for carrying out initial testing. Though, for exceptional cases where flow meters require to be tested under extreme conditions that cannot be managed by the manufacturer, they are sent to a big independent facility. For example, to calibrate large line size gas ultrasonic flow meters for custody transfer applications, the calibration facility must be equipped to handle high-pressure conditions with high speed flowing natural gas that usually costs millions of dollars to build. Hence, in such cases, manufacturers delegate this task to specialized calibration units. However, when we calibrate a Flow Meter that has already been in application for quite some time, the process happens to be known as Recalibration. Various techniques […]
