E+H Flowphant T DTT31 Flow Switch in Industrial Processes DTT31-A1A111DE2AAB

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)

Summary Table

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.
