Silver Automation Instruments recently encountered multiple customer inquiries regarding latex flow measurement in different applications, including rubber glove manufacturing , Latex Compound for Mattress Production and needs skim latex flow rate for centrifuging processes in Natural Rubber Latex (NR) production. These applications present specific challenges due to latex’s viscosity, density variation, and the need for precise flow monitoring at very small flow rate.

Challenges in Latex Flow Measurement

Measuring latex flow presents multiple challenges due to its physical properties:

2. Density Fluctuation: Latex density may vary based on dry rubber content (DRC), requiring a flow meter that accounts for mass flow measurement instead of just volumetric flow measurement. Oval gear flow meter is a kind of volumetric flow meter, if you need mass flow measurement, oval gear flow meter cannot meet your demand.
3. Non-Newtonian Behavior: Some latex formulations exhibit non-Newtonian characteristics, making them difficult to measure using conventional flow meters.
4. Adhesion Issues: Latex has a tendency to coat sensor surfaces, leading to measurement drift or blockage in some flow meter types. Hence if the flow meter without moving parts ,it will fix the adhesion issues problem.
5. Low Flow Sensitivity: Some latex processing applications, such as skim latex flow measurement, require high accuracy at low flow rates. Low flow rate is not easy for measurement.

Advantages of Using Coriolis Flow Meters for Latex Measurement

Coriolis flow meters are ideal for latex flow measurement due to the following benefits:
1. Direct Mass Flow Measurement for latex: Unlike volumetric flow meters,such as oval gear flow meter, Coriolis meters measure mass flow, eliminating the impact of density fluctuations in latex.
2. High Accuracy flow meter and with good Repeatability: Coriolis meters provide very precise measurement even for varying viscosity and density levels, the best accuracy can reach to 0.1%, ensuring consistent latex processing.
3. No Moving Parts: Since Coriolis flow meters have no mechanical moving parts, there is minimal wear and tear, reducing maintenance needs in latex measurement, also avoid adhesion issues.
4. Resistant to Coating and Buildup: The smooth, non-intrusive mass flow sensor tube design minimizes the risk of latex coating or clogging, maintaining long-term latex flow measurement reliability.
5. Low Flow Measurement Capability: Coriolis meters can accurately measure low flow rates,it can detect 2 kg/hr flow, making them suitable for applications such as skim latex flow monitoring in NR centrifuging.
6. Temperature and Pressure Resilience: The mass flow meters function well within the latex processing temperature range and pressure conditions. It can max bear 350 degree C high temperature and can make every high pressure mass flow meter.
7. A mass flow meter can measure multiple parameters. In addition to measuring the instantaneous flow rate of latex paint, it can also measure the totalized flow, density, temperature, and pressure of the latex paint.

Conclusion

For precise and reliable latex flow measurement in various applications, Coriolis flow meters provide superior accuracy, mass-based measurement, and long-term durability. Whether in rubber glove production, latex mattress manufacturing, or NR centrifuging processes, Silver Automation Instruments’ Coriolis flow meters ensure accurate flow monitoring and improved process efficiency.
