Product Details
Product Overview: Flowphant T DTT31 Flow Switch
A robust thermal flow switch engineered for safe, low-pressure-loss monitoring of liquid flows, the Flowphant T DTT31 comes with a user-friendly
digital display and rotatable housing for flexible installation.
Key Specifications
- Measurement Range: 0.03 to 3 m/s (0.1 to 9.84 ft/s) — displayed as relative mass
flow percentage.
- Measurement Accuracy: Varies by range — 2% to 10%.
- Operating Temperature: –20 °C to +85 °C (–4 °F to +185 °F); can withstand CIP cleaning
up to 130 °C.
- Max Pressure: Up to 100 bar (~1740 psi).
Functionality & Design Features
- Thermal (Calorimetric) Sensing Principle: Measures flow rate by detecting heat transfer from a heated
sensor cooled by the passing liquid.
- Outputs:
- 1 or 2 PNP switch outputs
- Optional 4–20 mA analog output for flow or temperature readings.
- Display & Usability:
- Built-in digital readout for quick onsite checks.
- Top housing rotates up to 310°, and the display itself rotates — making readings accessible from
any angle.
- Configurable via Endress+Hauser’s FieldCare (or ReadWin 2000) software for easy setup and data management.
Applications & Approvals
Ideal for a variety of industrial uses, including:
- Monitoring cooling water in pumps, turbines, compressors, and heat
exchangers
- Leak detection and lubrication cycle checks
- Filter integrity in beverage production lines Certifications:
- Marine-approved for use in maritime settings (DTT31 variant)
- 3-A hygiene-certified for food and beverage applications (available in DTT35 variant)

Why It Stands Out
- Minimal pressure drop ensures process efficiency.
- Highly configurable outputs and rotation features cater to diverse installation needs.
- Local display and PC configuration options make setup, monitoring, and maintenance straightforward.
- Flexible approvals (marine or hygienic) increase its versatility across industries.
