XGUHZ-50C series of magnetic float level meter

Application notes：
1. User equipment on the flange should pay attention to ensuring manufacturing and welding Form position tolerance,
Otherwise, it will affect installation and use.                         
2. Liquid level gauge must be installed vertically. The verticality shall be less than 5 degrees.                                                       
3. The shape structure diagram“L1” is called the side-mounted magnetic liquid level gauge "Shen tube distance"(also called the
blind area). This is an important parameter that the user must understand. It is an important parameter in the basic parameters of the liquid level gauge.
According to Archimedes theorem, the length of the magnetic float level meter depends on the density of the measured
liquid medium. The smaller the density of the liquid medium, the longer the magnetic float Lead tube from the lower lead
pipe to the bottom of the "Shen tube distance" length is; on the contrary, the shorter the. Design for ease of
design. Correct use by users, Installation, Special typical liquid density, and the control table of the sink can be used as
reference.                                                                
4. To prevent transients, the magnetic floater in the main duct has high-speed movement and impact. Liquid level gauge: Cathy
will use a magnetic float fixed at the bottom of the lead liquid pipe. Users should be installed before the installation of the
use of the card before you can install.                                         
5. Liquid level gauge must be installed vertically to ensure the magnetic float moves freely in the main pipe.                                  
6. The liquid level meter and container should be equipped with a stop valve to cut off the material for cleaning and maintenance.            7. Liquid level gauge: There is no promise to be accurate; it will directly affect the normal operation of the liquid level meter.           
8. After installation of the liquid level gauge, A magnet for correction: for the magnetic double column guide, to make the zero less show red, zero or more show white.                                                         
9. Liquid level gauge: First, open the lead liquid pipe valve. Let the liquid medium balance into the leading tube,
Avoid liquid medium with a rapid rise in float difference, caused by magnetic flip failure or turn a mess(in case of this phenomenon, can have magnetic recalibration).                                          
10 Open-end flange bli: When using a magnetic float,d pay attention to the side of the magnetic end with a magnetic upward, Can not flip.                
11 . Liquid level gauge:e There should be no solid impurities or magnetic impurities entering to avoid blocking the float and weakening buoyancy.                                                                 
12. According to the media, in the main pipe of the sewage valve, remove sediment in the tube.

Q1: What are the advantages of it compared to glass tube level gauges and radar level gauges?
Answer: The core advantage of a magnetic float level gauge is "mechanical display+fully sealed". Compared to glass tube level gauges, it does not have the weakness of fragile glass and easy leakage. The medium and indicator parts are completely isolated, making it more suitable for toxic, corrosive, and high-pressure media. Compared to electronic level gauges such as radar, it does not require a power supply, is not afraid of dust and steam interference, is not affected by dielectric constant, has a lower price, and can still reliably display in situations where there is a power outage or no power supply on site. The three can complement each other: for the highest cost-effectiveness, selecting a magnetic float for on-site display, remote monitoring, and installation of a transmitter are required.

Q2: Can harsh working conditions such as high temperature, high pressure, and strong corrosion be used?
Answer: It can be used, which is precisely its strength. The magnetic float level gauge can withstand high temperatures (up to around 400 ℃, depending on the seal and material) and high pressures (up to PN40 and above). The float and cylinder can be made of materials such as 304/316L stainless steel, PP, PTFE lining, etc., which can cover most corrosive media such as acids, alkalis, oils, solvents, etc. When selecting, as long as the four parameters of medium, temperature, pressure, and density are reported to the manufacturer, suitable materials and structures can be matched.

Q3: Is it only for on-site display or can it be connected to the central control system?
Answer: Both are possible. The main body itself is a set of electrically free on-site display instruments; If remote monitoring is required on site, a remote transmitter (magnetostrictive or reed switch type) can be installed to output 4-20mA, HART, RS485, and other signals connected to DCS/PLC. A liquid level switch can also be installed to achieve high/low level alarm interlocking. That is to say, a meter can be used as a "cheap and durable mechanical meter" or upgraded to a "smart liquid level gauge with signal", with flexible solutions and later expandability.
Q4: Can it be safely used in flammable and explosive chemical plants and storage tank areas?
Answer: Sure. The magnetic float level gauge itself is purely a mechanical structure, and the indicating part is transmitted through magnetic coupling, which does not generate electrical sparks and is naturally suitable for hazardous areas. When remote transmission is required, intrinsically safe (Ex ia) or explosion-proof (Ex d) certified transmitters can be selected. Therefore, it is very suitable for petroleum, chemical, storage tanks, LNG, pharmaceutical, and other occasions where explosion prevention is required.
