Black Glass Balls for Flow Meters and Instruments
REDHILL supplies black glass balls for flow meters, valves and precision instruments. The dark color provides strong contrast against clear fluids and light backgrounds. As a result, operators can read the ball position more easily.
Key Technical Specifications
- Composition: Colored glass; the exact formulation depends on the glass type.
- Structure: Amorphous glass.
- Appearance: Black, with a smooth, polished surface.
- Electrical Properties: Electrical insulator.
- Magnetic Properties: Non-magnetic material.
Density and hardness vary with glass composition. For example, flow meter calibration depends on ball size and density. Therefore, specify both values when selecting a ball.
Optical, Chemical and Thermal Properties
For optical uses, specify the wavelength range and required light transmission. In addition, define the surface finish and visual quality that your device needs.
Chemical resistance and temperature limits depend on the glass type. Therefore, match the material to your process fluid, cleaning agents and thermal cycle. Also confirm that the cleaning method suits the selected glass.
Applications of Black Glass Balls
For example, common uses include:
- Flow Meters and Rotameters: Balls for visual flow measurement.
- Check and Dosing Valves: Balls for liquid dispensing systems.
- Laboratory and Medical Instruments: Components for flow and position indication.
- Cosmetic Packaging: Check balls in dispensing pumps.
Available Grades and Sizes
- Precision Grade: G25.
- Diameters: 1.0–25.4 mm (up to 1 inch).
Available combinations depend on ball size, glass type and finish. Finally, send us your diameter, grade, quantity and working conditions. We can then confirm suitable options and lead time.
