Solutions to common failures of float-type water level sensors

- Jul 02, 2020-

As we all know, any machine is composed of various parts, and if one of the small parts has a problem, then it will affect the entire product. For example, when we use the water level sensor, we often encounter some small problems, but we don't know how to solve it. After reading this article, you will learn how to solve the common faults of the float type water level sensor.

Question 1: The signal output is abnormal and there is magnetic field interference

Solution: eliminate magnetic field.


Question 2: The water level sensor does not operate during operation

Solution: reconfirm the specific gravity of the float. Then check whether there are objects stuck in the float, and then check and clean.


Question 3: Floating ball movement, but no signal output

Solution: Check whether the float position is offset and adjust the float position; or the reed switch is damaged, replace the reed switch.


Question 4: The signal remains and the float cannot be recovered

Solution: The floating ball can't return, check if the floating ball is caught by the objects, remove it. Or the float is leaking, replace the float.


The above is the problem we encountered when using the float type water level sensor, how can we avoid these problems? Because the float type has been around for a long time, it is just a simple level switch, but some issue can not be avoid when we use it, such as stuck.


We all know that the rapid development of science and technology now, without innovation, products that will never stop will be eliminated. For the floating ball type, it cannot be used in viscous or liquids containing impurities, etc., and the float is easy to be stuck and does not move, and the photoelectric liquid level sensor does not have these problems, and the appearance design of the photoelectric liquid level sensor can avoid these issues.
