Flow switch for monitoring of flow rates and temperature
- Measuring range: 0.03 to 3 m/s (0.1 to 9.84 ft/s)
- Max. measured error 2% - 10% (per measurement range)
- Max. process pressure 120 bar (1.740 psi)
- Medium temperature range -20...+85°C (-4...+185°F)
- Top housing section can be rotated 310° which make it possible to read the measured values in all orientations
Flowphant T DTT31 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.
- 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
