Application of Tuning Fork Level Switch for Measuring PVDF Floats in Water at Zhejiang Chemical Industry
Background Introduction
A Zhejiang Chemical Industry requires precise measurement of PVDF (polyvinylidene fluoride) levels in their storage tanks during the production process. These PVDF materials float in water and are adhesive, making it difficult for traditional level measurement instruments to achieve stable and reliable measurements. To address this measurement challenge, the company chose the Jiwei Fork-11 tuning fork level switch, which has shown significant effectiveness.
Why is Measuring PVDF Levels Floating in Water a Challenge?
Measuring PVDF levels floating in water presents several challenges: PVDF, due to its density being close to that of water, often remains in a suspended state and does not easily form a floating accumulation, making it difficult to measure its level stably. Additionally, PVDF is greatly affected by water flow, stirring, or fluctuations. Most domestic tuning fork level switches are prone to false actions or signal instability when subjected to vibrations and fluctuations in water. Furthermore, the buoyancy characteristics of PVDF may change over time, temperature, or chemical environment, further increasing measurement uncertainty.
Jiwei’s Solution to the Key Problems
In the application at Zhejiang Chemical, the Jiwei Fork-11 tuning fork level switch primarily addressed the following key issues:
- Traditional level switches often fail to provide reliable measurements when detecting floating materials. The Fork-11 tuning fork level switch features a wider and longer fork design, capable of measuring materials with densities as low as 8 mg/cm³. It can measure sediment levels with a density difference of 10 mg/cm³ in water, naturally enabling the measurement of PVDF particles with densities close to water.
- PVDF easily adheres to the surface of the tuning fork probe, leading to unreliable measurements. The Jiwei Fork-11 tuning fork level switch is designed with an anti-sticking feature, effectively preventing PVDF material adhesion and ensuring measurement accuracy.
Actual Application Results
In the PVDF production line at Zhejiang Chemical, the Fork-11 tuning fork level switch has been installed in multiple storage tanks, successfully achieving accurate detection of floating materials and providing reliable level data. These data have helped optimize the production process, ensuring continuity and stability. Additionally, the precision-tuned Fork-11 fork body has significantly improved sensitivity, and its anti-sticking function has effectively resolved the adhesion issue of PVDF. On-site operators reported that the design of the Jiwei Fork-11 significantly reduced the frequency of equipment cleaning and maintenance. Its comprehensive self-diagnostic functions accurately locate fault information, improving production efficiency.
Conclusion
Zhejiang Chemical Co., Ltd. adopted the Jiwei Fork-11 tuning fork level switch for PVDF level measurement, successfully achieving precise and stable level measurement by solving the challenges of floating material detection and adhesion. The practical application case demonstrates that the Fork-11 tuning fork level switch not only improved the continuity and stability of the production process but also reduced maintenance costs and enhanced production efficiency. It provides an efficient and stable solution for level measurement in similar conditions.
