Flow Switch - Code 240

Parker Conflow's 240 is an Intrinsically Safe flow switch used to make or break an electrical circuit at selected flow levels in underground mining and quarrying applications.

Parker Conflow's 240 is a flow switch used to make or break an electrical circuit at selected flow levels in underground mining and quarrying applications. It is Intrinsically Safe (IS) and Flameproof Apparatus (FPA) offering many safety and regulatory compliance benefits.

The flow switch is based on the Code 452 Flowmeter. It works by the moving magnet coming into close proximity with an electrical reed switch, which closes its contacts in the presence of a magnet. The position of this reed switch is set to coincide with a given flow, thus closing or opening the electrical contacts at this flow level. The unit can be used for any situation where a minimum, or maximum, flow condition needs to be satisfied.

Code 240 is available in 1/2" and 1" sizes and operates at a maximum working pressure of 207 bar. It has a wide flow Switching range from 9 LPM - 90 LPM.
