Standard 8000XHT Series flow meters are calibrated with water at approximately 25°C / 77°F. The use of fluids other than water may affect the accuracy of measurement due to differences in viscosity. Proteus’ world-class calibration capability allows us to deliver instruments with specialized fluid- and temperature-specific calibrations.
