Product Overview

The SUP-PTU300 Flow-through Turbidity Meter is designed for continuous online monitoring of low-level turbidity in drinking water and clean water applications. Utilizing a 90° scattered light measurement principle and a sealed flow-through measuring chamber, it provides stable, high-precision measurements with minimal maintenance. Supporting RS485 Modbus RTU communication and optional 4–20 mA output, the PTU300 integrates easily with PLC and SCADA systems, making it an ideal solution for municipal water treatment, water distribution networks, industrial process water, and environmental monitoring.

Key Features

  • Designed specifically for clean water applications, the PTU300 provides stable low-range turbidity monitoring with excellent repeatability, making it ideal for drinking water quality control.
  • The enclosed flow-through measuring chamber minimizes ambient light interference and maintains a consistent sample environment, resulting in more reliable measurements than traditional immersion sensors.
  • Integrated temperature compensation, ambient light compensation, and automatic cleaning functions help maintain measurement accuracy while reducing maintenance frequency.
  • Standard RS485 Modbus RTU communication and optional 4–20 mA output allow seamless integration with PLC, DCS, and SCADA systems.
  • The optimized hydraulic design requires only a small continuous sample flow, reducing water usage while ensuring fast response and accurate monitoring.
  • Built for continuous industrial service, the PTU300 delivers long-term stability with minimal operator intervention, making it suitable for unattended installations.

FAQ

Why is a flow-through turbidity analyzer better than an immersion sensor?

A flow-through analyzer measures water inside a controlled optical chamber, reducing interference from ambient light, bubbles, and external contaminants. This results in more stable and accurate low-turbidity measurements, especially in drinking water applications.

Which turbidity range should I choose?

Choose the measurement range based on your application:

  • 0–1 NTU for ultra-low turbidity drinking water
  • 0–20 NTU for general water treatment
  • 0–100 NTU for higher turbidity process water

Selecting the correct range improves both accuracy and resolution.

Does the PTU300 require a continuous water sample?

Yes. The analyzer is designed for continuous flow-through operation and performs best with a stable sample flow. This ensures consistent optical conditions and reliable real-time monitoring.

Can the analyzer be integrated into an existing control system?

Yes. The PTU300 supports RS485 as standard and offers an optional 4–20 mA output, allowing easy integration with PLC, SCADA, and DCS systems.
