Stainless Steel Flow Switch, G1/2'', G1/4''

High-pressure 316L flow switch is hot-selling now. This 316L stainless steel flow switch features a high-strength structural design with pressure resistance up to 100 bar, suitable for high-pressure water circuits and industrial oil systems. The flow switch offers multiple probe lengths from 15mm to 60mm to accommodate various pipe diameters. Diverse output options include relay output (up to 5A load) and 4-20mA analog signal for seamless integration with user control systems.

Feature

• All-Stainless Steel Construction: The flow switch features an integrated ANSI 316L stainless steel sensor and housing design, delivering exceptional corrosion resistance and mechanical strength for stable operation under 100 bar high-pressure conditions.
• Wide Measurement Range: Supports detection of water, air, and oil across diverse fluid conditions. Combined with an adjustable response time of 2-10 seconds, it ensures measurement accuracy while maintaining system stability.
• Multiple Output Options: The SUCH flow switch supports PNP, NPN, relay, and 4-20mA output signal formats. Power supply options include 24VDC, 110VAC, or 220VAC, accommodating most industrial control scenarios.
• Visual Status Indication: Six built-in LED flow indicators provide an intuitive display of current flow rate changes and setpoint status. Combined with potentiometer adjustment, this enables rapid on-site configuration and calibration.
• Robust Protection Design: Features reverse polarity protection, short-circuit protection, and overload protection. Withstands temperature gradient changes of 300K/min and maintains stable performance across a medium temperature range of -20°C to 80°C.

Dimension (unit: mm)

In the above dimensional drawing, the length of Y is determined by the power supply method, with two options available:

• 24VDC power supply: Y length is 45mm
• 85~265VAC power supply: Y length is 60mm

The length of L is determined by the sensor length you select, with five options available (i.e., 15mm, 20mm, 30mm, 45mm, 60mm).

Wiring Diagram

Note

• When powered by 85~265VAC, both high and low point actions cannot be activated simultaneously. Please pay special attention to this specification during selection.
• When powered by 24VDC, connect brown to positive and blue to negative. The flow switch's internal transistor or relay output defaults to conducting or activating when above the set point. Conversely, connect blue to positive and brown to negative for the output to conduct or activate when below the set point.
