Various techniques can be adopted to recalibrate a Flow Meter. 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. Hence, in such cases, manufacturers delegate this task to specialized calibration units. 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.įor 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. ![]() Majority of the manufacturers own, self-calibration facilities for carrying out initial testing. RECALIBRATIONĪfter the manufacturing process is over, flow meters like any other measuring device must first be calibrated before putting them out to use. 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. ![]() In other words, the comparison of an instrument or a measuring device to a standard reference is known as Calibration. INTRODUCTION:Ī calibration process involves correctly setting up the measuring instrument so that it enables accurate reading on the scale.
