Product Overview
The TAD series ultrasonic in-line flow sensor from XY-TEK integrates sensing and signal processing in a compact housing to provide continuous liquid flow measurement without external computing hardware. With no moving parts, the sensor minimises mechanical wear and measurement drift while producing negligible pressure loss, making it suitable for systems demanding stable pressure and flow control.

Key Features

• High measurement accuracy and long-term stability
• Bidirectional liquid flow measurement with bubble detection
• Integrated electronics inside the sensor — no external circuitry required
• No clogging or moving parts; minimal pressure drop
• Standardised electrical outputs for easy system integration

No Blockage
The TAD in-line flow sensor has no internal moving parts, reducing the risk of blockage and minimising pressure losses in the fluid line.

Reliable and Durable
Constructed from corrosion-resistant materials, the TAD sensor is designed for demanding industrial environments and long continuous operation.

Compact in Size
With an integrated circuit and compact footprint, the TAD sensor supports connection to various tubing materials and is straightforward to install and commission.

Control System Integration
The TAD sensor offers multiple selectable output modes for seamless integration into automation and control systems.
