MET-1015A-5L
Sensor-separated float switch!!
The method involves using a magnetic proximity switch installed outside the liquid tank, which is activated by a magnet built into the float. The float moves up and down in accordance with the liquid, allowing for the detection of the liquid's water level. Point 1: By focusing on magnetic detection, we have made it possible to separate the sensor part from the float switch using our unique long-distance detection technology and float technology. Since there is no sensor part inside the liquid tank, the removal of the liquid tank from the device becomes smoother. Point 2: We have overcome the issue of liquid adhesion to the inner surface of the liquid tank with externally attachable capacitive sensors or ultrasonic sensors. There is also no malfunction caused by bubbles near the surface, provided that the float does not lose its buoyancy due to the bubbles. Point 3: Since there is no sensor part inside the liquid tank, there is no need to be careful when handling it during cleaning or other maintenance.

Float switch
The float detects the rise and fall of the liquid level, activating the switch! Float switch.
【Overview】 This float switch features a reed switch embedded in the main body that reacts to the rise and fall of the liquid level, interacting with a magnet attached to the end of the float shaft to provide ON and OFF contacts. Please design the installation position at the center of the required level. The distinction between upper and lower limits can be made simply by changing the orientation of the float. In particular, the AL-40F model is equipped with a terminal box, making it very user-friendly. ★For more details, please request documentation or download the catalog★

Float Switch ML Series
Float Switch ML Series
Introducing the ML series float switches handled by Heisei Measurement Co., Ltd. 【Features】 ○ A magnet is placed inside the float that follows the liquid, embedding a reed switch with contacts that open and close due to magnetic force within the stem. This provides the simplest switch that offers an ON (closed) or OFF (open) signal when the float reaches the set level. ○ Distinguishing between ON (closed) or OFF (open) at the rising contact signal can be done simply by changing the orientation of the float. ○ Output: Contacts only ○ Contact capacity: 0.5A-100V ○ Operating temperature: MAX 100℃ ○ Operating pressure: MAX 1.0MPa ● For other functions and details, please download the catalog.

[Column] What is a Float Switch? Mechanism of Operation and How to Use It
What is a float switch? Introducing its mechanism and usage! Proven results in various fields!＼For control board development, go to Nippo!／
A float switch is a type of level switch that operates in response to changes in liquid level, using a float ball that floats on the surface of the liquid. Due to its simple structure, it is used in many places such as apartments, buildings, and factories. ■ Mechanism of Operation Inside the float, there is a magnet, and when the float approaches the reed switch, the contacts of the reed switch close, allowing the electrical circuit to conduct. Conversely, when the float moves away from the reed switch, the contacts of the reed switch open, cutting off the electrical circuit. By detecting the position of the float, which moves up and down according to the displacement of the liquid surface, the water level in the tank can be monitored. ■ Usage A stem (core rod) is fixed to the bottom or top of the tank, and it is connected to the electrical wires drawn from the reed switch. This electrical signal is used to control submersible pumps or valves. Recently, there are services that allow remote monitoring of the water level in tanks located in distant places via a web server, enabling users to understand the tank's condition from an office without having to visit the site. Our company applies the above technology and is engaged in development across various fields. Please feel free to contact us.
