A magnetic flap level gauge uses a magnetic float as the measuring element; the flipping of the flap is driven by magnetic coupling, eliminating the need for power. Even its basic model can display readings on-site without requiring any additional electrical power. It is suitable for a wide range of conditions, from high temperatures to low temperatures, and from vacuum to high pressure, making it an ideal liquid level measurement device for industries such as petroleum and chemicals. However, in the production process, we often need magnetic flap level gauges that can provide alarm functions for high and low liquid levels, in order to control these levels and ensure the normal and stable progress of production. How can magnetic flap level gauges be made to have such alarm functions? For the special on-site requirements of some customers, the alarm switching points may not be just one or two; multiple alarms can occur. This can be achieved by equipping each magnetic level gauge with multiple alarm switches, and the principle remains the same as that of a single alarm point. In this way, we can achieve alarms for high and low liquid levels using an alarm switch; the alarm signal generated is a standard digital signal, and this digital signal is used to control the activation and deactivation of external feeding equipment, thereby automatically regulating the liquid level inside the tank. The high/low level alarm magnetic flap level gauge uses a float as the measuring element, with magnets driving the flap for display, and it requires no power source. Users can install controllers on the main pipeline of the magnetic flap level gauge at the upper and lower limit positions set by them; these controllers are equipped with self-retaining reed switches. As the magnetic float moves with the liquid level, it activates the reed switch, thereby enabling alarm or limit control functions. The switch consists of a reed switch and a circuit module, featuring a compact structure and durability. Based on their application, they can be divided into ordinary level control switches, level control switches with hold (memory) function, and high-temperature level control switches with hold (memory) function. To enable the functions of these two control switches, an external 24VDC power supply must be configured simultaneously. This level control switch is fixed to the outside of the UHZ type magnetic flap level gauge in a bundled manner, thus placing it within the same magnetic field system as the level gauge. As the magnetic float moves up and down with the liquid level, the reed switch corresponding to that level position is attracted by the magnetic field generated by the float. The conversion module then transforms this changing signal into a passive switch signal for output. In the case of a modern alarm switch, it is able to retain the signal until a return sensing signal arrives, at which point it releases the signal. Therefore, it can be easily used in conjunction with various types of instruments to achieve control and alarm functions.
