ITT Unveils New McDonnell & Miller Flow Switches at AHR EXPO
|
Morton Grove, IL - January 15, 2008
ITT has announced a new McDonnell & Miller brand general-purpose,
liquid flow switch. The M&M Series FS250 switches incorporate new
enhancements that provide greater reliability and lower flow sensing
capabilities in a general-purpose flow switch.
|
|
|
The new Liquid Flow Switches have a measured flow-rate sensing of 5.8 gpm in 1"
pipe (horizontal pipe installations), which is up to 18-percent lower than
measured flow of other general purpose flow switches. The new McDonnell &
Miller Liquid Flow Switches have a one-inch NPTM brass pipe connection, 1", 2", 3",
and 6" stainless steel paddles, and ASME Section IV boiler ratings of
250-degrees (Fahrenheit) and 160 psig.
Switching mechanisms on both the flow switch models FS251 and FS254 include:
· Flow detection via stainless steel paddles inserted into flow stream piping
· Brass body, paddle arm and pivot shaft
· EPDM O-ring seals on the pivot shaft for long life and durability in multiple chemical environments
· Cam actuation of electrical switch
· Easily accessible electrical connections and flow sensing adjustment screws
|
|
Featuring a best-in-industry five-year warranty, the McDonnell & Miller Liquid
Flow Switches were subjected to extensive lab and field-testing for a number of
applications, including copper tube boilers, chillers, and commercial pools.
The new McDonnell & Miller Liquid Flow Switches are designed to be direct replacements
for existing flow switches.
