How to Ensure Accurate Turbidity Monitoring in Pulsation and Bubble Conditions

In not only water treatment plants but also food and beverage manufacturing, wastewater treatment, and industrial cooling water management, turbidity monitoring plays a critical role in maintaining process quality and operational safety. However, these environments often experience flow fluctuations (pulsation) and bubble formation within the pipelines, which can make real-time monitoring challenging.

The.Wave.Talk’s laser-based inline turbidity meter (continuous turbidity analyzer) IQ-50 has demonstrated exceptional measurement stability even under such demanding conditions, setting a new standard for turbidity management.

1. Pulsation Test – Consistent Measurements Despite Flow Variations

KTR Certified Test Results (Pulsation Conditions)

In pulsation condition tests jointly conducted with KTR, the IQ-50 maintained highly stable performance, with readings shifting only slightly from 0.031 NTU → 0.036 NTU and the Relative Standard Deviation (RSD) staying low at 2.19% → 5.57%.

In comparison, conventional turbidity meters under the same conditions showed significant fluctuations, jumping from 0.021 NTU → 4.144 NTU, with the RSD surging from 14.31% → 34.96%. These results clearly show that the IQ-50 provides reliable and accurate data, even in environments where flow variations are frequent.

2. Bubble Test – Accurate Monitoring Despite Bubble Interference

Jointly tested and validated with KTR

In tests replicating environments with bubble interference, the IQ-50 once again demonstrated stability, maintaining readings at 0.040 NTU → 0.045 NTU and an RSD of 3.38% → 4.23%.

By contrast, conventional turbidity meters recorded notable instability, rising from 0.020 NTU → 0.077 NTU, with the RSD jumping from 8.90% → 26.51%. This validates how the IQ-50’s optical signal amplification and multi-scattering analysis technologies effectively suppress bubble-induced noise to ensure precise, real-time monitoring.

3. Maintenance-Free, Cost-Effective Design

The IQ-50 is designed for direct inline installation without the need for additional components such as constant-flow pumps, tanks, or bubble-removal devices. This design not only reduces installation and operational costs but also minimizes maintenance burdens, making it an ideal solution for facilities where operational efficiency is critical.

4. Value Across Industrial Applications

The IQ-50 is versatile and well-suited for municipal water systems, food and beverage production, wastewater treatment, and industrial cooling water management, where accurate and stable turbidity monitoring is essential.

• Real-time, data-driven quality control

• Process stability and reduced failure rates

• Predictive maintenance and improved operational efficiency

  
  

These advantages help organizations build sustainable and efficient water quality management systems across a wide range of applications.
