Field of application
The switch is designed for the safe measurement, display and monitoring of relative mass flow rates of liquid media with practically no pressure loss. It can be selected between one or two switch outputs as well as one switch output and one standardized analog output for flow rates or temperature values. Typical applications are: Monitoring cooling water circulation processes or lubrication systems of pumps and heat exchangers or leak monitoring in process lines.
Flow switch for monitoring and displaying relative mass flow rates of liquid media in the range from 0.03 to 3 m/s (0.1 to 9.84 ft/s). Flowphant T DTT31 − with thread connections or coupling.
Application examples:
Monitoring cooling water circulation systems of pumps, turbines, compressors and heat exchangers
Leak monitoring in process lines
Monitoring pump functionality
Monitoring lubrication systems
Filter monitoring in the beverage industry
Benefits
Practically no pressure loss
Configuration software FieldCare for quick configuration and reliable storage of device settings
Optional: second switch output or 4 to 20 mA analog output for temperature monitoring or for outputting the flow as a percentage
Function check and process information onsite thanks to digital display at device
Top housing section which can be rotated 310° and rotatable display make it possible to read the measured values in all orientations
