Can a float level gauge be used for a 1000 m³ methanol storage tank? If it’s not possible, then why not? What kinds can be used?

Features of the UHZ-25 series magnetic float level gauges: 1. Suitable for measuring the level and interface of liquid media in containers. In addition to on-site indication, it can also be equipped with remote transmitters and alarm switches, offering comprehensive detection functions. 2. The indication is novel; the readings are intuitive and prominent, and the direction of the indicator can be adjusted according to the user’s needs. 3. It has a large measurement range and is not limited by the height of the storage tank. 4. The indicator mechanism is completely isolated from the medium under test, featuring good sealing performance, high reliability, and safe operation. 5. Simple structure, easy to install and maintain, corrosion-resistant, power-free, and explosion-proof.

Features of UHZ magnetic flap level gauge: 1. It uses a float as the measuring element, with magnets driving the flap for display, requiring no power source. 2. Equipped with upper and lower limit switch outputs, it enables remote alarm and limit control. 3. By installing a transmitter, it is possible to achieve remote indication, detection, and control of the liquid level

　Principle of magnetic flap level gauge The magnetic flap level indicator is installed on the outside or above the tank, and is used to indicate and control the level inside the tank. A drain valve can be added as needed. The connecting flange is equipped with a control instrument that allows for customization of the liquid level height; the indicator consists of magnetic color chips, and as the magnetic float inside the main tube rises with the liquid level, the color chips flip, thereby indicating the liquid level height. A magnetic switch or a remote transmitter can also be installed on the body tube to output a switch signal or an analog signal. Suitable for high-temperature, high-pressure, and corrosion-resistant environments; it offers local display and remote control capabilities. The main tube is made of seamless steel pipe; the connection sections are welded by hole-pulling, with no scratches inside. The installation method can be side mounting or top mounting, with the lower end of the unit sealed. 　　Selection of Magnetic Flip Board Level Gauges Magnetic flip board level gauges, also known as magnetic level gauges, magnetic rod level gauges, or magnetic float level gauges, operate on the principle of magnetic coupling. These devices overcome the various shortcomings of glass tube level gauges, such as their inability to function under high temperatures and pressures as well as their fragility. Magnetic flip board level gauges can be installed either on the side or at the top; in either case, a remote transmission device can be used, allowing the level gauge to display the liquid level both locally and remotely. Such level gauges are referred to as remote-type magnetic flip board level gauges. Although the manufacturing process for magnetic flip board level gauges is simple, since they are used as measuring instruments, especially remote-type ones, it is difficult to ensure product quality if they have not been approved by the quality supervision authorities and do not possess a production license. Therefore, when purchasing such gauges, it is important to choose manufacturers with a production license and a good reputation. The price may be slightly higher, but the product quality and after-sales service will be guaranteed. 　　Use of magnetic flap level gauges Glass plate level gauges can be used directly to observe the liquid level in various containers. It is suitable for level indication in industrial fields such as petroleum and chemicals. This level gauge features a simple structure, provides intuitive and clear readings, does not get clogged or leak, is easy to install, and requires simple maintenance. Flanges are installed at the upper and lower ends of the glass plate level gauge and connected to the container, forming a communicating vessel; through the glass plate, it is possible to directly observe the actual height of the liquid level inside the container. The upper and lower valves are equipped with safety balls; in the event that the glass is damaged accidentally, these balls automatically seal the gap under the pressure inside the container, preventing the liquid from leaking out and ensuring the safety of the operators.

　　The tubular level gauge is a new type of level gauge that combines the advantages of glass tube level gauges, plate level gauges, and boiler level gauges. (It overcomes the weaknesses of traditional glass tube level gauges, such as susceptibility to breakage, lack of durability, safety concerns, inability to withstand high pressure, poor visibility, and low operating temperatures.) To a certain extent, it can replace glass plate level gauges, and it is cheaper than level gauges with similar specifications. 　　A tube level gauge is a direct-reading liquid level measurement instrument suitable for on-site detection of the liquid level in various storage vessels used in industrial production processes. It features a simple structure and accurate measurements, making it a traditional tool for on-site liquid level measurement. Each end of this level gauge is equipped with a needle valve; in the event that the glass tube breaks due to an accident, the needle valve closes automatically under the pressure in the container, preventing the medium inside from continuing to flow out. 　　Features:
1. Intuitive display.
2. Simple structure for easy maintenance.
3. Combines the advantages of UG, UB, and UGS (UNS) at a low cost.

Main technical specifications:
1. Measurement range: 100, 150, 200, 250, 300.
2. Operating pressure of the medium being measured: 1.6 MPa, 2.5 MPa.
3. Operating temperature of the medium being measured: -10°C to +200°C.
4. Connection thread: G3/8 or M16

Why not? It’s possible; I’ve seen it before. If the answer is no, it’s probably because of pressure concerns.
