Flow meters are devices used to measure the volume or mass of a gas or liquid, and are referred to by many names such as, flow gauges, flow indicators, liquid meters or flow rate sensors. 

CALIBRATION - RECALIBRATION
Calibration is nothing more than comparing the output of a measuring device with a reference.  Re-calibration is a popular word for doing a “re-check” and is often referred to as when a purchased flow meter has been sent back to the factory for a periodic calibration check.  Re-calibration is the same as calibration, the flow instrument will be compared to a fixed reference, again.

IS CALIBRATIONS NECESSARY?
Every instrument is subject to aging, wear and dirt.  In order to ensure the instruments measure values representing the truth, a periodic check is often recommended.  For some applications a periodic check is even required due to legislation, norms, or directives.

PERFORMING CALIBRATION CHECKS – HOW OFTEN
Mass flow instruments, in fact all process instruments, experience wear from the conditions of the process in which they are installed. Temperature, electronic component tolerance shift, contamination build up over time (even very slight), plus other factors will all contribute to affecting the accuracy of an instrument. Your instruments should regularly undergo, at a minimum, a calibration check if not a recalibration. But how often?  Because the nature of each application is different (conditions, running time, etc.) a calibration can last three years or three months.

CLEANING AND CALIBRATING INSTRUMENTS YOURSELF

Cleaning and repairing:
  It is possible to restore the function of the instruments if no parts are irreversibly damaged. However, it can affect the accuracy of the device.
Calibration:  It is possible to calibrate an instrument by checking its measured value with an accurate reference yourself.
