Flow-Through Turbidity Meter

The Flow-Through Turbidity Meter is a professional instrument designed for precise, real-time continuous measurement of liquid turbidity. It is widely applied in industrial production, environmental monitoring, and water quality testing, providing critical data support for process control and water quality safety assurance in water treatment plants, chemical production, and the food and beverage industry.

How the Flow-Through Turbidity Meter Works

The Flow-Through Turbidity Meter operates on the principle of optical scattering. When a beam of light illuminates the liquid flowing through the measurement chamber, suspended particles cause the light to scatter.

The instrument detects the intensity of this scattered light, compares it with the incident light intensity, and converts the optical signal into a precise turbidity value using advanced algorithms. Higher concentrations of suspended particles typically result in greater scattered light intensity and a higher measured NTU value.

Core Components for Precise Measurement

The Flow Cell is the core component, providing a stable, controlled space for liquid flow. Made from corrosion-resistant glass or plastic with excellent optical properties, it ensures uniform flow without turbulence for maximum accuracy.

The high-precision Optical System utilizes stable LEDs or laser sources and sensitive photodetectors to capture scattered light signals. The Signal Processing Unit then converts these signals into intuitive turbidity values displayed on a clear screen.

Detailed Product Structure and Operation

Integrated Flow Control and Connectivity

A dedicated Flow Control System, comprising a flow meter and control valve, ensures a stable flow rate through the measurement chamber, which is critical for repeatable and high-precision turbidity measurement results.

The inlet and outlet use quick-connect or threaded fittings for fast, leak-proof connection to external pipelines. The sturdy enclosure and versatile mounting bracket allow for flexible installation on walls, benches, or directly on pipelines.
