McDonnell Miller Low Water Cutoffs
Series 63, 64, 764, 67, 69, 150, 157, 764, 42, 93, 94, 193, 194

McDonnell Miller Low water cut offs, whether snap switch or probe-type models, provide a reliable method of controlling a boiler feed pump. Mounted at the boiler water line, it starts and stops the pump as the boiler water dictates. Consequently, it holds the boiler water level at the limits recommended by the boiler manufacturer to maintain maximum steaming efficiency.

McDonnell Miller Water Feeders
Series 101-A, 47, 51, 53, 247, 21, 551, 847, 851, 47-2, 51-2, 53-2, 247-2

McDonnell Miller Water Feeders open if the boiler’s water line drops to the feeder / cut-off combination’s feeder operating point. The feeder will open mechanically and add water to the boiler.

McDonnell Miller Switches
No. 2, 5, 7-B, 11

The McDonnell Miller is the brains of the Water Feeders and Low Water Cut Off. The switch tells the boiler when to turn on or off depending on the level of water in the boiler.

McDonnell Miller Liquid Flow
Series FS4-3, FS4-3T, FS5, FS8-W, FS1, FS1-W, FS6, FS6-W

The flow of liquids in pipelines plays an important role in industry and coerce. Under most circumstances it is essential to know whether or not there is a flow in a pipeline, and to act upon that knowledge.
