koelmiddelniveau

Koelmiddelniveau refers to the level of the cooling medium in the reservoir or tank of a cooling system. The term is used in both industrial process cooling and automotive or mechanical cooling contexts to describe how much coolant is available for circulation and heat exchange.

The level is a critical parameter because it affects pump suction, flow rate, and heat transfer efficiency. If the level is too low, the pump can draw air, leading to cavitation, reduced cooling performance, or pump damage. If the level is too high, spills or foaming can occur and heat transfer can become less effective. In many systems, maintaining the level within a defined band is essential for reliable operation.

Measurement and control methods vary by system. Open cooling circuits may show the level in a sight glass or on a dipstick, while closed systems use expansion tanks with level sensors, float switches, or ultrasonic sensors. Automatic controls may top up from a make-up line or trigger alarms and shut-downs if the level deviates beyond acceptable limits. The coolant concentration and quality are also important; additives for corrosion inhibition and anti-foaming agents are often part of the maintained level, especially in automated systems.

Common issues include temperature-driven expansion, leaks, evaporation, contamination, and air entrainment, all of which can distort readings and affect cooling performance. Regular maintenance should include checking and calibrating sensors, cleaning sight glasses, verifying correct concentrate and water ratios, inspecting hoses and seals for leaks, and venting air to prevent air locks. Proper disposal or recycling of spent coolant follows local regulations.
