01AUTOMOTIVE REPAIR & SPECIALITY TOOLS
Precision sensing for every drop
A compact instrument that turns the invisible movement of water into clear, readable data. Its transparent casing allows you to watch the internal rotor spin, offering a direct visual confirmation of flow alongside the electronic signal.
Designed for integration into water heaters, vending machines and cooling loops, this G1/2" sensor suits technicians and engineers who require accurate volume tracking within tight mechanical spaces.
02DESIGN
See-through housing for visual verification
The valve body is crafted from a transparent material, allowing immediate observation of the water flow and rotor conditions without disassembly. This open design provides a layer of physical assurance, letting the user verify that the mechanism is turning in sync with the electrical output.
04SPECS
Low-power operation across voltage ranges
Operating within a DC 5V to 18V range, the sensor draws a maximum of 15 mA at 5V, making it energy-efficient for battery-powered or low-voltage control boards. It handles pressures up to 1.75 MPa and connects via a standard G1/2" thread, simplifying installation into existing plumbing or tubing setups.
FIT
Compact form factor for tight installations
Weighing only 0.1 kg in its carton, the unit is lightweight and flexible in appearance, designed to fit into constrained spaces such as credit card machines or compact water testing rigs. Its small size facilitates easy installation without requiring significant modification to the surrounding hardware.
