Critical Technical Advantages
-
Minimal Process Impact: The thermal measuring principle allows for a sensor design that creates practically no pressure loss in the piping. This ensures that the installation of the monitoring switch does not degrade the efficiency of pumps or cooling circuits.
-
Versatile Signal Output: Depending on your control requirements, the DTT31 can be configured with two independent switch outputs (for low-flow and high-flow alarms) or one switch output paired with an analog output. The analog signal can represent either the flow as a percentage or the process temperature.
-
Superior Onsite Visibility: The device features a clear digital display for immediate function checks and process information. To ensure readability in tight or awkward installations, the top housing section can be rotated 310°, and the electronic display itself is also rotatable.
-
Intelligent Configuration: Using FieldCare software, device settings can be configured quickly and stored reliably. This allows for rapid commissioning and the ability to duplicate settings across multiple units in a facility.
-
Ruggedized for Marine and Industry: The Flowphant T is built for demanding environments, featuring marine approvals and a robust design that stands up to the vibrations and conditions found near pumps, turbines, and compressors.
-
Integrated Temperature Monitoring: In addition to flow, the DTT31 monitors the temperature of the medium, providing an extra layer of process data without the need for a second instrument.
