Standard 500 Series metering flow switches 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 temperature- and fluid-specific calibration.
