TIS is now IANZ accredited for the calibration of volumetric flowmeters using a gravimetric weighing method of a delivered volume. We are also a Blue-tick accredited service provider for the verification of water meters to comply with consent requirements.

TIS own a portable flow rig that is self-contained, that can be used in the TIS workshop, or on a customer's site, to verify flowmeters used for water.

Portable clamp-on calibration checks are also able to be performed for a "non-intrusive" and "in-situ" calibration method.
