Abstract
A low water cutoff (LWCO) device having a probe features a signal processor or processing module configured to receive signaling containing information about a difference in conductance between samples of a foam/unstable fluid line for a predetermined foam difference count that are measured on at least one test channel and sensed by the probe arranged inside a boiler, including a steam or hot water boiler or burner; and provide corresponding signaling containing information to turn OFF the boiler, based upon the signaling received.

A low water cutoff (LWCO) device having a probe, comprising:
- a signal processor or processing module configured to
- receive signaling containing information about a difference in conductance between samples of a foam/unstable fluid line for a predetermined foam difference count that are measured on at least one test channel and sensed by the probe arranged inside a boiler, including a steam or hot water boiler or burner;
- and
- provide corresponding signaling containing information to turn OFF the boiler, based upon the signaling received.
A method to detect the presence of a foam/unstable fluid line in a boiler using low water cutoff (LWCO) device having a probe, comprising:
- receiving, with a signal processor or processing module, signaling containing information about a difference in conductance between samples of a foam/unstable fluid line for a predetermined foam difference count that are measured on at least one test channel and sensed by the probe arranged inside a boiler, including a steam or hot water boiler or burner;
- and
- providing, with the signal processor or processing module, corresponding signaling containing information to turn OFF the boiler, based upon the signaling received.
