The S420 can be removed from the compressed air or gas line easily for calibration or exchange purposes. The opening can be closed with the optional closing cap (see order information). This is a special advantage as most flow meters on the market require an expensive bypass line in such a case. The re-installation of the measurement device is simple as the sensor unit fits into the pipe section only in one position. NEW: The design of S420 enables the removal of the “measuring device” without any dismounting of the measuring section.
