Ultrasonic flow sensor TPD series

volumefor oilfor liquids and slurries

Product Overview
The TPD series inline ultrasonic flow sensors/flow meters use an integrated design with built-in electronics to provide direct inline flow measurement and on‑site data monitoring. Tubing range DN15–DN50; OEM and tube‑size customization supported. The sensor installs via standardized tubing fittings and offers overview accuracy up to ±2%. The straight through flow path contains no moving parts or dead zones, reducing wear, scaling and pressure loss. Unlike clamp‑on sensors, TPD calibration is not dependent on tubing material or diameter, enabling immediate measurement after integration.

Applications

• Industrial automation: filling machines, spray systems, liquid cooling circuits, lubrication and cleaning systems
• Battery manufacturing: slurry transfer, water cooling loops for thermal management
• Water treatment: process measurement in wastewater and treatment systems
• Liquid cooling for electronics, data centers and energy storage systems
