A magnetic flipboard level gauge is a type of level measurement instrument that is very common in large storage tanks. It operates on the principle of buoyancy: an internal float within the gauge floats up and down inside the main body (which is connected to the container), rising and falling as the level of the liquid being measured changes. The magnetic components of this internal float are used to attract the indicator inside the flipboard, thereby providing a clear indication of the changes in the liquid level within the container. It can be used directly to observe the liquid level in various containers. It is highly suitable for level indication in industrial fields such as petroleum and chemicals, and is used for detecting the liquid level in various equipment including towers, tanks, vats, spherical containers, and boilers. Thanks to its simple structure, intuitive and clear visibility, lack of clogging or leakage, easy installation, and straightforward maintenance, the magnetic flap level gauge is particularly popular among users. Magnetic flap level gauges come in two installation types: side-mounted and top-mounted. In either case, it is possible to attach a remote transmission device, allowing the level gauge to display the liquid level locally as well as enable remote monitoring of the level. A magnetic flap level gauge with such a remote transmission device can be referred to as a remote-type magnetic flap level gauge. Magnetic flap level gauges are available in stainless steel, stainless steel with PTFE lining, and plastic casings. Select the appropriate material based on the medium temperature, pressure, and corrosion severity. It is widely used in chemical enterprises; its advantages include intuitive display, safety and reliability, as well as few malfunctions. It overcomes the shortcomings of glass plate (tube) level gauges, such as poor indication clarity and susceptibility to breakage; it offers no blind spots in the entire measurement process, provides clear readings, and has a wide measurement range. Magnetic flap level gauge, V-cone flow meter. How to determine whether a magnetic flap level gauge is in good condition: 1. Seal the lower flange of the magnetic flap level gauge, and slowly pour clean water into the float chamber through the upper connection flange. If the indicator shows the correct liquid level accurately without any fluctuations, then the level gauge is functioning properly ； 2. Remove the float chamber flange, insert the float into the float chamber in the direction indicated by the arrow (with the magnet inside the float located in its upper half), then reinstall the float chamber flange. Make sure to install the seal properly and tighten it evenly ； 3. If the indicator is of the tracking type, a spare magnetic tool can be used to lift the indicating float, thereby coupling it with the magnetic float inside the float chamber (for float-type indicators), or the magnetic tool can be used to pull the indicator from bottom to top so that it gives the correct reading. How magnetic flap level gauges enable the measurement of liquid level and provide alarms in chemically sealed storage tanks is something that operators in chemical processing facilities should know, and it is also something that our professional manufacturer, Chengfeng Instruments, ought to explain. Over the years, our company has received numerous inquiries regarding the selection of level gauges for chemical storage tanks. So, how exactly does a magnetic flap level gauge achieve the measurement of liquid level and provide alarms in chemically sealed storage tanks? Users of level transmitters: As required by their superiors, it is necessary to install high-level alarm devices on hazardous chemical storage tanks (which are sealed tanks). In the past, simple glass tube level gauges and magnetic flap level gauges were used on such tanks. How can electronic level gauges be installed? It was considered to use submersible level transmitters connected to secondary instruments in order to set up high-level alarms; however, upon consulting manufacturers, it was learned that it is not feasible to use submersible probe sensors in sealed, pressurized tanks. These probes function by detecting pressure changes resulting from the position of the fluid, and therefore they cannot be used when the tank is under pressure. How can this be resolved properly? (While considering explosion protection and corrosion resistance) The media to be measured include ethanol, toluene, propylene oxide, and chloromethane. A detailed modification of glass tube level gauges involves installing capacitive sensors on them. If the liquid is opaque, even adding a photoelectric sensor will work. If it cannot be built in, consider modifying the existing setup. A glass tube level gauge can accurately display the liquid level inside a sealed tube; all that is needed is to ensure that the position on the glass tube can be detected.
