Long-term stability and guaranteed precision are essential requirements for flow measurement instruments. Regular calibration is particularly important for measuring points that have a bearing on quality and safety.

Calibration of flowmeters

On-site or factory calibration?With one of our mobile calibration rigs, flow measurement instruments can be calibrated quickly on-site – often with the instrument still installed – by comparing the flow measurement instrument against a certified reference in the calibration unit. This saves time and money, and the cost benefits are even greater if several instruments require calibration. If the required precision cannot be obtained using the mobile facility, the instruments exceed the nominal range that can be handled on-site, or maybe only a single instrument requires calibration, then one of our accredited calibration centres is probably more suitable. Here, your measurement instruments are calibrated, and adjusted if required, within a guaranteed timeframe.
