The ultimate purpose of the side-mounted magnetic flap level gauge is to open or close the circuit when the liquid rises or falls. Imagine a magnetic flap level gauge, such as a light switch, which opens and closes the contacts to control whether the signal current can pass.
There are two types of magnetic flap level gauges, the normally closed magnetic flap level gauge and the normally open magnetic flap level gauge. Normally closed means current is flowing, while normally open means not flowing. When the magnetic flap level gauge is turned off, it means that it is in a normal state. This is either leaning on the cable or floating baffle.
Normally closed magnetic flap level gauges are often used as high level switches, which means that when the liquid lifts the float and disconnects the circuit, they will shut down the filling pump. Generally, the open-circuit magnetic flap level gauge is usually used as a low-level switch. For example, when the liquid is lower than the switch level, the normally open magnetic flap level gauge closes the drain pump.
If a certain level must be maintained, the magnetic flap level gauge is very suitable for automatic pump control and alarm. One of the most common uses of side-mounted magnetic flap level gauges is flood prevention.
For example, if the fuel tank is too full, there is a risk of overflow. However, with the side-mounted magnetic flap level gauge, the pump can be automatically turned on or off according to the level of the fuel tank.
But, what happens if you choose the wrong type of magnetic flap level gauge to use with the level controller? If you use automatic pump control to manage the liquid level, the wrong magnetic flap level gauge may send out inaccurate or wrong signals to turn the pump on or off at the wrong time. This can cause overflow, pump failure, or both. Therefore, damage, repair costs, and business loss are all possible consequences of floods, and we know that you don’t want to deal with this pain. We are here to help you determine which type of side-mounted magnetic flap level gauge is best for your business and flood protection!
Choose a side-mounted magnetic flap level gauge for flood control
There are several factors you need to consider when choosing a magnetic flap level meter. When purchasing equipment, you need to consider location, tank size, and liquid temperature. If your level controller does not meet the specifications you need, then your automatic pump control will be more likely to fail, resulting in overflow.
temperature
Not all magnetic flap level gauges can withstand high temperatures. If the liquid you are using is kept at extreme temperatures, you need to consider this when choosing a magnetic flap level meter. For example, our stainless steel horizontal magnetic flap level gauge and vertical magnetic flap level gauge can work at temperatures up to 500°F. Make sure that the magnetic flap level gauge you use can operate under the temperature and conditions of the material to achieve the best flood protection.
Built-in hysteresis
Do you need a controller to add logic to the on/off equation of the magnetic flap level gauge? If so, this will also affect your decision. If the pump is controlled by a switch without logic and the liquid level stops on the float, any ripples on the surface will cause the float to bounce up and down. This bounce will turn on and off the automatic pump control, quickly burning the motor. However, the hysteresis control provided by the Kari multi-level cable magnetic flap level gauge will tell the pump to close at one level and only open at another level. You don’t want to burn out the motor, thus effectively preventing the pump from working and causing flooding.
Number of exchange points
When deciding which magnetic flap level meter to buy, please consider how many switch points you need. Some magnetic flap level gauges consist of a switch point and are mainly used for simple alarm applications. These types of traditional magnetic flap level gauges are usually the cheapest, but you may need to spend more to adapt to your application. You may need a magnetic flap level gauge, which has four switch points, or even seven.
