Float level sensors represent a range of devices that are used for measuring the level of liquids in a given vessel. The FRN22212 is a device from this type, and it is used in applications ranging from metering the flow of oil and other liquids, to informing when a specific level of a product is reached in a certain container. This article will explore the various functions and features of the FRN22212, as well as its working principles.

Production Specifications

The FRN22212 is designed to be used in applications with variable range up to 12 meters in height. The sensor is powered by four 1.5v batteries, and features a magnetic holds switch. It is designed for operation in temperatures up to 85°C, with a tolerance level of 0.2°C. The device has a rated voltage of 5 VDC, and works at a frequency of 50 Hz.

Vessel Compatibility

The FRN22212 is designed to be compatible with a variety of vessels. The device can be used with either stainless steel or glass for elevated temperatures, and it is also suitable for polypropylene tanks, which it is most often used for. The device is also compatible with tanks made from various combinations of polymers and fractional reservoirs such as polysulfone, PVC, and Polyvinylchloride.

Working Principle

The FRN22212 float level sensor works on the principle of buoyancy. Buoyancy is the tendency of a body of liquid to raise an object when pressure is applied to one end of it. Thus, when a magnet is placed in a vessel filled with a liquid, it will create a magnetic field which is attracted to the object. This magnetic field will cause the float to move up or down depending on its position in the liquid, and thus measuring the level of the liquid in the vessel.

Features

The FRN22212 float level sensor comes with a variety of features that make it suitable for a wide range of applications. For one, it features an automatic reset function that restarts the sensing cycle should the liquid level fall below the set limit. The device also includes a permanent magnet, so that the float can be firmly held in place and remain within the desired range at all times. It also features a low power consumption, making it suitable for long-term use. The device also features adjustable sensitivity, enabling users to select the level of sensitivity that is most suitable for their application. Lastly, the device is resistant to corrosion due to its stainless steel construction, making it a reliable device for use in wet or moist environments.

Conclusion

In conclusion, the FRN22212 float level sensor is a powerful and reliable device for measuring the level of liquids in various vessels. It features an adjustable setting that allows users to select the most suitable sensitivity for their application, and it is also resistant to corrosion. Additionally, the device is powered by four 1.5v batteries and features a magnetic hold switch for firm positioning of the float. Ultimately, the FRN22212 is an excellent choice for applications in which the level of liquids need to be accurately and consistently monitored.
