Water Tank Float Switches and Level Sensors

Float switches are typically wired directly to a pump's control circuit or through a relay. When the float rises to a set level, it closes or opens a switch contact, sending a signal that starts or stops the pump. Proper installation requires matching voltage ratings, secure cable routing, and mounting the float at the correct height for the tank's operating range.

Float balls for level sensors are commonly manufactured from 304 or 316 stainless steel, chosen for corrosion resistance and durability in demanding environments. Available finishes include matte, brushed, or fully polished, with material selection depending on exposure to chemicals, temperature, and pressure within the specific tank or vessel application.

Yes, float balls can be manufactured with custom magnets sourced and assembled inside the ball for precise level detection in magnetic reed switch systems. This integration allows the float to trigger switches accurately as it moves along a guide rod, making it ideal for sump pumps, tanks, and automated liquid control systems.

Round float balls are typically available from 1-1/2 inch to 14 inch diameters, while oblong floats range from 2 x 6 inch up to 9 x 14 inch with various NPT and thread options. Custom sizes and shapes can also be manufactured to fit specific tank dimensions and mounting requirements.

Yes, 316 stainless steel float balls offer excellent resistance to corrosive liquids, making them suitable for chemical manufacturing, wastewater treatment, and other harsh environments. Material selection should be based on the specific chemical composition, concentration, and temperature of the liquid being monitored to ensure long-term reliability.

Float balls are pressure-tested using specialized equipment to verify they can withstand the specific pressure conditions of their intended application, such as vacuum tanks or high-pressure steam traps. This testing ensures the welded seams and internal cavity remain sealed and buoyant under real-world operating pressures before shipment.
