Ring-11 Liquid Level Switch
Passed SIL2 / SIL3 Functional Safety Assessment, certified for both Intrinsic Safety and Flameproof Enclosure explosion protection. With only 40mm fork length, the lowest measurable medium density can be as low as 0.5g/cm³. Process temperature can reach up to 250℃. Typical applications:
● Herbicides and fungicides in insecticide Factory.
● Storage tanks of oil, crude oil, gasoline and lubricating oil.
Ring-11 Liquid Level Switch is a highly reliable instrument for liquid level detection and control. The fork length is only 40mm which makes Ring-11 applicable not only for vessels, process tanks and storage tanks, but also particularly for pipelines or other applications with constricted space. Based on the fork resonant principle, when a fork vibrates in harmonic resonance comes in contact with measured liquid, its vibrating frequency will greatly decrease. The fork’s harmonic resonant frequency has been precisely pre-adjusted to achieve high sensitivity so the lowest measurable density can be as low as 0.5g/cm³. Jiwei Ring-11 liquid level switch is excellent in level measurement for acids like HCL, H2SO4, H2SO3, and alkali liquids, syrup, medical liquids, industrial wastewater, etc. And particularly, it is suitable for pressured liquefied gas, LNG and applications under complicated working conditions where measured liquid is easy to foaming, bubbling or with high viscosity and under vibration disturbance environment etc. The special setting of gas-tight leadthrough makes Ring-11 effectively prevent accidental leakage from high-pressure strong corrosive liquids.
Ring-11 Liquid Level Switch passed SIL2 / SIL3 Functional Safety Assessment, as well as certified for both Intrinsic Safety and Flameproof Enclosure explosion protection. Currently, Jiwei has been granted an invention patent (ZL201510735568.2) on Ring-11 Liquid Level Switch.
