Miselli XL/10 and XL/10T Series Vertical Level Indicator
The Miselli XL/10 and XL/10T Series Vertical Level Indicator is designed for visual fluid monitoring in hydraulic systems. Featuring a 254 mm (10″) center distance, it has a robust polycarbonate (PC) tube protected by a stamped sheet metal housing. Ideal for mineral and synthetic oils, it supports temperatures up to 90°C at 1 bar. The XL/10T variant integrates a capillary thermometer (0–100°C) for simultaneous level and temperature monitoring. Weight: 400 g.
The Miselli XL/10 and XL/10T Series Vertical Level Indicator ensures accurate and continuous visual monitoring of fluid levels inside tanks and hydraulic power units. The device provides an immediate and safe reading of the internal dynamics of the hydraulic fluid. The series stands out for its structural strength and reliability, essential features for use in industrial environments.
The main sight body is made of transparent cylindrical polycarbonate (PC), a polymer selected for its excellent mechanical properties and optical clarity. A robust external metal protection made of stamped sheet metal, finished in sandblasted black paint, is installed to protect the tube and prevent impact damage. The assembly includes precision mechanical components: a flanged nut and a drilled screw that ensure perfect hydraulic sealing. The total component weight is 400 grams. For special applications or chemically aggressive fluids, the manufacturer offers the option of equipping the indicator with a borosilicate glass tube.
The range is divided into two configurations to meet different monitoring needs:
The indicator is suitable for use with a wide range of fluids, including mineral oils, synthetic oils, hydraulic fluids, and glycol-based fluids. Technical data indicates limited chemical resistance when used with gasoline and diesel. The maximum operating parameters certify an operating temperature of up to 90°C, validated through testing carried out at 1 bar pressure. In case of different pressure or temperature conditions, or when using specific chemical agents, a dedicated technical assessment is required.
Installation is versatile and supports two different fixing methods on a precise hole center distance of 254 mm (10″):
