For those who are not familiar with it, the magnetic flap level gauge is likely to be quite unfamiliar. However, it is widely used in the field of level measurement, plays an important role in it, and provides great assistance to our work. In fact, having a sufficient understanding of level gauges is a prerequisite for making full use of their functions. The application techniques related to level gauges involve various aspects; in this article, we will briefly explain the structural principle of remote-transmission magnetic float level gauges. A magnetic flap level gauge is a measuring instrument that uses a magnetic float as the sensing element; it detects the level or interface of the liquid being measured through the magnetic coupling between the magnetic float and the magnet in the display column. By applying the principle of a communicating pipe, it is ensured that the liquid level in the container being measured is equal to that in the measuring tube. As the float in the measuring tube changes in height in proportion to the liquid level in the container, the magnet inside the float interacts with the magnet in the color column on the display panel, causing the color column to flip; white indicates no liquid, while red indicates the presence of liquid, thereby allowing for the direct display of the liquid level. Magnetic flap level gauges offer advantages such as intuitive and clear display, wide viewing angle, compact and rational design, safety and reliability, no issues with leakage, low maintenance requirements, and low repair costs. Moreover, their indicating function does not require additional power supply; thus, even in the event of a power failure, level monitoring is not affected. They are ideal instruments for level detection. Magnetic flap level gauges not only enable on-site display but also allow the measured level signals to be transmitted remotely via industrial signals such as standard 4-20mA to the corresponding centralized management control center, thereby facilitating remote centralized monitoring and control. Remote magnetic float level gauges are widely used, but to optimize their measurement performance, it is still necessary to take all aspects of the operating environment into consideration. Only by meeting the ideal measurement requirements of these magnetic float level gauges can we ensure that they provide accurate measurement data. So what are the requirements regarding the working environment? I. Temperature ； The temperature mentioned here refers to the temperature of the object being measured; for example, when measuring the liquid level in a storage tank, it refers to the temperature inside the tank. We know that the working principle of remote magnetic float level gauges relies on magnetism; it depends on the float, which is the key component. The float must be in contact with the medium, and there is a magnet inside the float that is responsible for its function. Excessively high temperatures can often weaken or even eliminate the magnetism of the magnet within the float. If the appropriate operating temperature of the float does not match the actual temperature, it leads to unstable magnetism in the float, or even loss of magnetism, which makes it impossible to carry out measurements. This is not only related to the purchase cost of magnetic flap level gauges, but it is also a key factor in ensuring cost-effectiveness in our procurement and selection process. II. Pressure ； What is referred to here is the high pressure surrounding the medium within the device; more precisely, it is the pressure inside the container being measured and in the conduit connecting to the remote magnetic float level gauge. The pressure parameter is very important; its level not only affects the thickness of the flange plates but also the diameter of the float and the thickness of the main steel tube. Another factor is the pressure resistance of the float – whether support is needed. If the pressure resistance of the float does not match the actual operating pressure, and if the actual pressure is much higher than what the float can withstand, it is very likely that the float will be crushed and become unusable. III. Chemical properties of the medium ； That is what is often referred to as the degree of corrosivity. This is a very important environmental requirement; if the medium being measured is highly corrosive, then the material used for contact with this medium in the manufacture of magnetic flap level gauges must be corrosion-resistant. For example, 304 stainless steel provides basic corrosion protection, while 316L offers slightly better resistance. Other options include PP materials with corrosion resistance, as well as stainless steel linings with Teflon coating for enhanced corrosion protection. A thorough understanding of the medium’s technical properties also helps us save on the costs associated with purchasing remote-transmission magnetic float level gauges, thereby achieving better cost-performance ratios.
