Calibration of industrial process measurement devices such as flowmeters is essential to ensure they continue performing their jobs efficiently and safely.

How often an instrument needs recalibrating will depend on how often it's used. A flowmeter that has corrosive liquid flowing through it may lose its accuracy much faster than one in more favourable conditions. It's generally recommended to recalibrate all devices at least once a year.
