Endress + Hauser Flowphant T DTT31 Flow switch

Safe monitoring of flow rates and temperature in industrial processes. Compact and cost-saving.

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.

Benefits

Practically no pressure loss

Configuration software FieldCare for quick configuration and reliable storage of device settings

Optional: 4 to 20 mA analog output to read out the flow rate as percentage value

Optional: second switch output or 4 to 20 mA analog output for temperature monitoring

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

Marine approval

Field of application

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
