Elesa® original design narrow shape fluid level indicators.
These oil level indicators are a low cost alternative to EN 650.
The liquid level is legible from all angles.
The polyamide body consists of two parts that are ultrasonically welded together. The oil level indicators are individually air pressure tested for leaks at 3 bar.
Also suitable for use on pressurized oil tanks. Pressure test results regarding resistance under pressure available upon request.
As a contrast screen, a white lacquered aluminum strip is used, which is marked with black graduations or temperature scale. The scale is placed behind and outside the liquid and therefore protected.
The protection frame is designed to increase the resistance of the indicator by absorbing all shocks. The protection frame is mounted to the indicator.
The shape of this oil level indicator gives a magnifying effect and the scale is very easy to read.
Maximum tightening torque of set screws/nuts: 6Nm
Oil level indicators made of alcohol resistant material available upon request.
Highly resistant to shocks, solvents, oils with additives, aliphatic and aromatic hydrocarbons, petrol, naphtha, phosphoric esters.  Avoid contact with hot water, alcohol and detergents containing alcohol.
Maximum continuous working temperature oil: 190°F (90°C).
