Liquid benzene level gauge

Liquid benzene level gaugeIt is a liquid level instrument that uses magnetic steel inside the float to drive the flipping of a two-color thin sheet to indicate the liquid level. The magnetic float inside the main body moves up and down with the rise and fall of the liquid level, while driving the dual color sheet inside the indicator outside the main body to flip. When there is a liquid level, it turns red, and when there is no liquid level, it turns white.

When in use, this level gauge can operate under high temperature and high pressure conditions, and the magnetic flap level gauge also has a certain degree of corrosion resistance during operation, which greatly increases the service life of the magnetic flap level gauge. At the same time, the body tube of the magnetic flap level gauge is made of seamless steel pipe, and the connecting tube is welded with pull holes without scratches inside.

There are basically no blind spots in the measurement range.Among numerous level gauge products, the magnetic flap level gauge stands out as a perfect replacement for glass tube level gauges. It compensates for many of the shortcomings of glass level display instruments, such as the fragility and cracking of glass products.

Liquid level gauge for benzeneFloat characteristics:

A strong 360 degree magnetic field keeps the magnetic flap stable even in turbulence.

The gravity design of * * ensures that the position of the float is consistent with the liquid level.

The contact surface of the float adopts a cylindrical shape for higher accuracy.

The built-in magnet has higher magnetism and anti attenuation ability, unlikeCeramic magnets lose their magnetism in high temperature environments.

The standard float material is 316 stainless steel: special float materials can also be consulted with Kenco.

The standard float reaches a small specific gravity of 0.50.

The combination of 360 degree magnetic field and KENCO magnetic transmitter is very ideal.

The float has no holes, so it will not leak water.

● Compact structure to save space.

So why is the float of the magnetic flap level gauge stuck? Today, we have summarized the following factors for everyone:

1. The float is stuck by iron filings or other impurities that are magnetically adsorbed by itself.

2. The ambient temperature is too low, causing the medium to freeze and preventing the float from rising or falling.

3. After a period of use, the float may become stuck by impurities and unable to move

4. The installation angle of the float is less than 87 degrees, and the tilted float affects its up and down movement

To avoid the above faults, 304 or 316L stainless steel materials should be selected during the production of the float, matching the inner and outer diameters of the float, and accurately measuring the size of the float according to the density and pressure of the medium on site. The product quality should be strictly controlled from various aspects such as material selection, design, and production to greatly reduce float faults and ensure the stable operation and normal operation of the magnetic flip plate roll switch.

​
As shown in Figure 3, the distance between liquid phase a and gas phase b of level gauge LT-1 is 1.95m; the distance between liquid phase c and gas phase d of level gauge LT-2 is 1.95m; the distance between gas phase port b of LT-1 level and liquid phase port c of LT-2 level is 0.5m; when the actual liquid level of LT-1 reaches liquid phase port c of LT-2 level, the signal of LT-1 level gauge does not output and will be displayed and operated by the upper level gauge LT-2, and the signal will also be output by LT-2 level gauge.
3.2 Modification of Range Values in the Database
As shown in Figure 3, the total height of the LT-1 level gauge is 1.95m, accounting for 57% of the 3.4m from point A to point D of the ammonia storage tank; The total height of LT-2 level gauge is 1.95m, accounting for 57% of the 3.4m from point a to point d of the ammonia storage tank; So the corresponding range values in the software database need to be modified to: LT1 range lower limit: 0%, range upper limit: 57%; LT2 range lower limit:

Errors in the use of liquid level gauges for liquid benzene:

The temperature affects the error generated by the magnetic flap level gauge. Currently, the magnetic flap level gauges used on site are connected vertically and parallel to the measured tank body. The liquid level height of the measured tank can be determined on site through the reading ruler on the instrument. The instrument with remote transmission function can be read on the secondary meter, which is very convenient and fast. However, it is common for the instrument reading to be inconsistent with the remote transmission reading of the secondary meter.
There are many reasons for this situation, including the superposition of measurement errors or inaccuracies that occur in abnormal states. But according to the experiment, the key to this problem comes from the measurement error caused by temperature changes. The working principle of a magnetic flap level gauge can be simply described as the principle of a connector in physics. Under normal circumstances, the height of the liquid inside the tested tank and the cavity of the magnetic flap level gauge must be equal. However, in actual use, the volume of the tested tank is relatively large. In order to protect the safe operation of the tank in harsh environments, a layer of iron sheet is wrapped around its exterior to prevent corrosion and also serve as insulation. Therefore, the temperature of the liquid inside the tank does not change significantly. However, the magnetic flip plate level gauge is often placed on the outside of the tank, which is greatly affected by external environmental factors.

Working principle of liquid level gauge:

The liquid level gauge works based on the principles of connectors and magnetic coupling. The magnetic flap level gauge is connected to the detected separator through upper and lower connecting flanges, upper and lower control valves, forming an interconnected structure with the separator.

When the liquid level in the separator is higher than the lower port of the level gauge, the liquid in the separator enters the main tube of the magnetic flip plate level gauge. The float in the main tube rises and falls with the rise and fall of the separator liquid level. The magnetic steel in the float drives the red and white flip columns on the magnetic flip plate to flip 180 ° through magnetic coupling. When the liquid level rises, the flip column turns from white to red. When the liquid level drops, the flip column turns from red to white. The red and white boundary positions on the magnetic flip plate are the actual height of the medium liquid level in the container, thus achieving on-site display of the separator liquid level.

Avoid the following operations when using a liquid level gauge for liquid benzene:

Due to wiring errors in the magnetic flap level gauge, which can result in inaccurate measurements or damage to the instrument, it is important to pay attention to the following points when wiring the magnetic flap level gauge:

1. When wiring, avoid large capacity transformers, motors, or interference sources;

2. For explosion-proof types, wiring must be carried out in accordance with relevant regulations to ensure explosion-proof performance;

3. Unscrew the terminal cover of the junction box, thread the cable through the cable connector, and connect it to both ends of 24VDC;

4. Connect the grounding terminal as needed;

5. Tighten the terminal cover of the junction box.

6. For explosion-proof instruments, wiring must be carried out in accordance with relevant regulations to ensure explosion-proof performance;

What adverse effects will high temperature have on the reed switch and remote transmitter of the magnetic flap level gauge

Magnetic flap level gauge is a widely used level gauge, suitable for on-site observation of liquid level measurement data. Because the panels are made of red, white or black yellow with clear colors and high resolution, even when the height exceeds 8 meters to 10 meters, the numbers on the display panel can still be clearly observed. But in some situations with certain requirements, it is necessary to transmit the measured data remotely in the form of power signals to a location that is convenient for centralized collection and observation, which requires the provision of corresponding remote transmission transmitters.
