Background
The liquid level signal device is widely used in various oil tanks and water tanks, including airplane oil tanks, airplane water tanks, oil storage tanks of gas stations, raw material storage tanks of chemical enterprises, water tanks of various public places and the like. The raw material of the tank is typically a single, well-sealed, opaque material that resists corrosion, particularly when the tank stores liquids that are corrosive or volatile. The liquid level annunciator arranged in the box body can send a designated liquid level signal to an operator or an operating system in real time so that the operator or the system can take proper measures.
Conventional level annunciators are generally custom-made products and are generally non-serviceable components that need to be individually designed based on factors such as the overall dimensions of the tank, the internal allowable installation space, the triggering level height, and whether the level triggering mode is ascending or descending. The common liquid level annunciators are mainly installed in two ways, one way is that the liquid level annunciators are installed on rib plates inside the box body through an installation disc, and the other way is limited by the installation position and needs to be integrated on other sensors inside other box bodies and mainly integrated inside the tubular capacitance sensor. The disadvantages of the traditional liquid level annunciator are that:

3) the traditional liquid level annunciator usually uses a single reed switch as a magnetic sensitive component, has poor reliability, and often causes serious problems that the alarm cannot be given or the alarm is not given all the time;
4) the magnetic sensitive component of the traditional liquid level annunciator is usually fixed inside the product in a sealing manner through glue pouring, and once the most core magnetic sensitive component fails, the whole product needs to be replaced, so that the maintenance or replacement cost of the product is increased. And the product after glue pouring can not adjust the signal alarm point any more, and the product adaptability is poor.
