Series 1100 Bronze & Stainless Steel Flow Switches
3/4” to 3” Pipe Size
DESCRIPTION
Series 1100 flow switches are manufactured to exacting standards and provide accurate flow detection for most applications. Product inspection involves calibrated tools and gages traceable to National Bureau of Standards.
The flow swtches are broadly used in machine tools, HVAC equipment and any process where the materials of construction and function are suitable.
Models are offered in bronze and 316 stainless steel housings with NPT threading. Optionally BSPT, SAE, Silver Braze & Socket connections are available.
FLOW SWITCH OPERATION
A magnet-equipped shuttle is displaced at the proper calibrated flow of liquid to actuate the hermetically sealed reed switch. At flow rates under the set point, clearance is provided for the liquid to continue to flow. When flow rates exceed the set point, the shuttle or piston is displaced even further to reveal a smooth, clear opening for a low pressure drop.
