Every TSI flow meter is tested and calibrated prior to

re-calibration date
The master meter at TSI is calibrated annually at the
Irish National Test Centre. This ensures the readings
obtained by the Test Equipment referred to on
certificates issued by TSI Flowmeters Ltd are traceable
to National and International standards
Annual calibration of the Flowmaster is recommended,
particularly if the meter is used on a regular basis.
Please return your meter to TSI Flowmeters Ltd for
calibration.
