43000 Series Flow Switches

Product catalog summary

Overview: The 43000 Series flow switches are designed for fast and accurate flow sensing, suitable for both fresh and saltwater applications. They offer a robust and reliable solution with a low-pressure drop.

Specifications:

Sensing Range: 0.75L to 1.0L per minute
Operating Pressure: Up to 20 bar (300 psi)
Temperature Range: -40°C to 125°C
Mounting Thread: 3/4" NPT
Mounting Orientation: Horizontal or vertical

Physical Description: The switch body is made from high-quality brass with 3/4” NPT threaded connections. It features a magnet and reed switch type assembly that can be easily removed for cleaning.

Installation Considerations: A 150-micron filtration is recommended to prevent debris accumulation. The switch can be cleaned without disturbing the installation by removing the retaining nut.

Operation: Flow through the switch depresses the shuttle, activating the reed switch via magnets in the shuttle.

Technical Specification:

Materials: Brass housing, PVC piston, Stainless steel SUS304 spring and retaining rings
Reed Switch: Carry current 1.5A, max current 1.0A, voltage 300V AC/250V DC, power rating 70A
Electric Connection: Flying leads AWG 22 to 18, 300m length, UL1430, lead-free wire
Accuracy: Set point accuracy ±10%, repeatability ±2%

Ordering Information: Right angle ¾” NPT brass flow switch, Part No. 43001

Performance Graph: A graph illustrates the relationship between pressure drop (psi) and flow rate (l/hour), indicating performance efficiency.
