The float floats up and down along the guide rod with the liquid level. There is a permanent magnet inside the float, and a reed switch is fixed inside the guide rod. When the float moves near the reed switch, the magnetic system acts on the reed switch and sends out a switch signal.ZYK610Float level switch is a classic application based on the simplest buoyancy magnetic principle, widely favored for its high reliability and cost-effectiveness.
Float (ball) liquid level controller is mainly used for controlling and alarming the liquid level of various storage tanks and containers in industrial production processes. When the liquid level is higher or lower than the set height, it can output 1-10 bit control signals (more can be customized) for control or alarm purposes. It is applicable to open or closed containers in metallurgy, chemical industry, shipping, environmental protection, power station, paper making, pharmacy, printing and dyeing, food, municipal and other industries, as well as water tower and pool level control and alarm for industrial or civil water supply and drainage.

Float level switchBased on the simplest buoyancy magnetic principle,It can also be called a float level switch, consisting mainly of a magnetic float, a plastic or stainless steel rod, and an imported reed switch. There is a permanent magnet inside the float that moves up and down along the guide rod. When it reaches the vicinity of the reed switch, the magnetic system acts on the reed switch and sends out a switch signal.


1. The installation position should be far away from the water inlet, otherwise the switch may cause misoperation due to fluctuations in the water inlet;
If the switch device is installed on the concrete pool wall, an L-shaped angle steel bracket can be added;
If the switch device is located in the mixing area, anti wave tubes or anti wave baffles can be installed;
4. Choose flange connecting pipes with an inner diameter greater than the diameter of the floating ball;
5. It is recommended to use a Φ 8mm multi-core cable for wiring;
6. The specific gravity of the tested liquid must be greater than the specific gravity of the float;
7. The action point of the float has been adjusted according to the customer's order requirements at the factory. Please do not adjust the position of the control point arbitrarily;
