Insertion Flow Switch, Target Type, G1/2'', G3/4'', G1''

High-quality target-type insertion flow switch detects liquid flow within pipelines, offering G1/2'‘, G3/4’', and G1'' connection sizes to accommodate various pipe diameters. Constructed from brass, the flow switch exhibits excellent pressure resistance and corrosion resistance, maintaining stable operation within a working pressure range of 0.05 to 1.6 MPa. Its internal reed switch normally open structure provides switch signals or dry contact signals with responsive sensitivity, making it suitable for flow detection and equipment interlock control.

Feature

• SUCH flow switches offer G1/2”, G3/4”, and G1” connection sizes, designed for different outer diameters to accommodate diverse pipeline system installation requirements.
• The flow switch supports dry contact switch signal output, operating under maximum DC24V or AC220V voltage conditions, with load current meeting common control system needs.
• The switch body is constructed from brass, offering excellent corrosion resistance and mechanical strength for diverse industrial environments. Featuring an insert-type design, installation requires only drilling a hole in the pipe and securing the unit.

Detail

Working Principle

A magnet is installed at the top of the water deflector. When water flow pushes the deflector open to a certain angle, the reed switch at the top detects the magnetic field above the deflector and outputs a switch signal/contact signal, i.e., the contact closes. When water flow is too low or absent, an internal spring resets the signal to open.
