What does a low level cutoff switch in a condensate receiver do?

A low level cutoff switch in a condensate receiver is designed to monitor the level of condensate within the receiver. When the level of condensate drops below a predetermined threshold, the low level cutoff switch activates. Its primary function is to stop the feed pump that is supplying water or condensate to the boiler or system.

Stopping the feed pump is crucial to prevent it from running dry, which could lead to pump damage and create a host of operational issues. By cutting off the pump when the condensate level is too low, the system ensures operational safety and protects equipment from potential failures that could arise from insufficient liquid levels. This mechanism is a vital safety feature in steam systems and helps maintain the integrity and reliability of the steam generation process.

The other options do not accurately represent the primary function of the low level cutoff switch, as it does not regulate flow rate, increase pressure, or open the exhaust.
