FAQs

1. How can I choose the correct capillary tube size for Kinematic Viscometer ?

The capillary tube size in Kinematic Viscometer depends on the fluid’s expected viscosity. Lower viscosity fluids need smaller diameter tubes, while higher viscosity ones need larger tubes. Using the wrong tube size may lead to inaccurate results due to very fast or very slow flow. Reference tables in or the user manual can help pick the right size. It is best to keep several calibrated tubes available for different types of samples.

2. How does the automatic timing function work in the Kinematic Viscometer ?

It Kinematic Viscometer automatically detects when the fluid passes through two timing points on the capillary tube and records the flow time. This eliminates the need for a manual stopwatch, reducing the chance of human error. The system offers a timing accuracy of ±0.1 seconds, ensuring reliable results for both fast and slow-flowing fluids. It then uses the recorded flow time along with the tube’s constant to calculate the kinematic viscosity.

3. Is there a delay or hold function before timing starts in the Kinematic Viscometer ?

The Kinematic Viscometer has a delay feature that allows the fluid to reach the correct test temperature before timing begins. This helps avoid errors caused by temperature differences in the sample. The system starts timing only when the fluid reaches the upper timing mark in the capillary tube. This improves the accuracy and repeatability of the test, especially for sensitive fluids.

4. What types of errors or faults can be automatically detected on the Kinematic Viscometer ?

Kinematic Viscometer includes a self-check system that finds common faults like wrong timing, incorrect temperatures, sensor problems, or cleaning issues. If a problem is found, the system shows a warning or error message on the screen. This helps avoid wrong test results and reduces unplanned maintenance. Users should still check the system regularly and keep it clean and calibrated.

5. What should we do if the Kinematic Viscometer shows inconsistent viscosity readings?

The Kinematic Viscometer may give uneven results if there are issues with the capillary tube or testing conditions. First, check if the tube is clean, undamaged, and correctly positioned. Ensure that the temperature is stable and the sample is fresh and uncontaminated. You can also use a standard fluid to verify the instrument’s performance. If inconsistencies continue, fully clean the system, recalibrate the temperature, and inspect the sensors for faults.
