Proteus flow meters monitor cooling flow and other liquids in industrial applications.

800 Series Metering Flow Switches

Standard 800 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.  DETAILS

8000 Series Liquid Flow Meters


Proteus 8000 Series instruments provide accurate, rugged, reliable and cost-effective measurement of heat transfer fluids and other liquids from -40 to 90 °C. Customized versions can be adapted for use with liquid temperatures to 150 °C and above. A built-in relay can be used to sound an alarm or shut down a system before damage is done to valuable equipment and products.  DETAILS

8000XHT Series - Extreme-Temperature Flow Meters

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.  DETAILS
