ITA-*-RG reflex level gauge features prismatic reflective grooves. Based on optical contrast, it shows black below liquid level and bright white above with clear boundary. Suitable for high temp & pressure, unaffected by medium turbidity and color, widely applied in petrochemical and power industries.
Below the liquid level: Light refracts into the liquid, appearing black.
Above the liquid level: Light reflects off the back of the glass plate, appearing white/bright red.The strong black-and-white contrast ensures clear level boundary identification even under direct sunlight.
Applications: High-temperature, high-pressure harsh working conditions with turbid/colored media (such as heavy oil, crude oil, sewage).
Features: Strongest anti-interference ability, unaffected by medium color and turbidity, the most commonly used model in petrochemical and power plant industries.
