Diesel level gauge

The liquid level gauge works based on the principles of buoyancy and magnetic coupling. When the liquid level in the tested container rises or falls, the float in the main tube of the level gauge also rises or falls accordingly. The magnetic steel inside the float is transmitted to the on-site indicator through magnetic coupling, driving the red and white flip columns to flip 180 °. When the liquid level rises, the flip column changes from white to red, and when the liquid level drops, it changes from red to white. The red and white boundary of the indicator is the actual height of the medium liquid level in the container, thus achieving the indication of the liquid level.

The SURE-UHZ series magnetic flap level gauge (diesel level gauge) uses a magnetic float as the measuring element, a magnetic steel driven flip column display, and does not require energy. Suitable for various environments ranging from low temperature to high temperature, vacuum to high pressure, etc. It is an ideal liquid level measurement product for industries such as petroleum and chemical. The magnetic flap level gauge is equipped with upper and lower limit switches for output, which can achieve remote alarm and limit control. Configure the transmitter to achieve remote indication, detection, and control of liquid level. According to the different installation positions on the container, two methods are provided: side installation and top installation. According to different media, two materials are provided: stainless steel and ABS engineering plastic; ABS is particularly suitable for corrosive media such as acids and alkalis.

Difference in lining selection for diesel specific level gauges:

The stainless steel lined anti-corrosion magnetic flap level gauge adopts a stainless steel body lined with polypropylene (PP) and polytetrafluoroethylene (PTFE) technology, which has high structural strength and corrosion resistance, and can be applied to acidic liquids such as hydrochloric acid, alkaline liquids, and organic solvents. But it is not suitable for measuring concentrated nitric acid, chlorine containing solvents, aromatic agents, aliphatic and other medium liquids. There are two types of side mounted anti-corrosion magnetic flap level gauges with stainless steel main body lined with polytetrafluoroethylene (PTFE) and stainless steel lined with polypropylene (PP), which are suitable for measuring corrosive media.
The side mounted lined magnetic flap level gauge (PTFE) is suitable for measuring liquid levels in corrosive media and high operating temperatures. It adopts advanced stainless steel lined PTFE stretching and flanging technology, with reliable structure and long service life. It is the best choice for measuring the liquid level of highly corrosive media such as hydrofluoric acid.

The side mounted lined magnetic flap level gauge (PP) is suitable for measuring inorganic corrosive liquids such as hydrochloric acid and dilute sulfuric acid. Due to the use of imported high-strength materials that can be close to metals, especially the unique insulation properties of PPR, this product is suitable for outdoor water tank level measurement and will not freeze inside in winter But it is not as good in temperature and pressure resistance as PTFE lining, and this product has a higher cost-effectiveness when the temperature and pressure are lower.

2、 Characteristics of diesel specific level gauge:
1. Using a float as the measuring element and a magnetic steel driven flip column display, no energy is required.
2. Equipped with upper and lower limit switch outputs, it can achieve remote alarm and limit control.
3. Equipped with a transmitter, remote liquid level indication, detection, and control can be achieved.

3、 Installation and maintenance of diesel specific level gauge
1. The installation must be vertical to ensure that the floating ball component can move freely up and down inside the main tube.
2. No magnetic conductors are allowed to approach the main body, otherwise it will directly affect the correct operation of the liquid level gauge.
3. After installation, it is necessary to calibrate the flip column guide with magnetic steel to display red below zero position and white above zero position.
4. When the liquid level gauge is put into operation, the valve of the lower drainage pipe should be opened first to allow the liquid medium to smoothly enter the main pipe, avoiding the liquid medium from rapidly rising with the floating ball component, which may cause failure and disorderly flipping of the column. If this phenomenon occurs, it can be recalibrated with magnetic steel after the liquid level stabilizes.

5. If your design process involves connecting flanges that are different from our company's model or using other standards, we can supply according to your requirements;

6. The measurement range of the instrument is the center distance between two connecting flanges (excluding top mounted types), where the center of the lower connecting flange is the zero point indicated by the instrument;

7. The measurement range of the instrument is the center distance between two connecting flanges (excluding top mounted types), and the length of the distance between the drain valve and the center distance of the flange is determined by the density of the applicable medium

8. You should ensure that the end faces of the connecting flanges on the equipment have appropriate flatness, perpendicularity, and center distance to ensure the installation and use of our products;

9. The float chamber (or main tube) should be kept clean and free of impurities, especially ferromagnetic substances. When the medium is not clean, adsorption or filtration devices should be added to ensure the normal operation of the instrument.

Due to the fact that the main diesel level gauge in the liquid chamber is made of stainless steel 1crl8Ni9Ti, there is no need to worry about rusting and corrosion issues;
Due to its simple layout, there is no need for too much time and cost in terms of repair and maintenance;
Even if a longer visible length is necessary, a single diesel level gauge can meet the requirements without the need for a staggered layout of multiple gauges (* * * with a large center distance of 12 meters);
The liquid level reflected by the display is easy to observe, that is, when the horizontal width is wide (39mm), the red and green colors are very clear and visible. White appears every 100mm in the liquid department, making it easy to estimate the liquid level;
Due to the function of magnetic mesh filter, it is also suitable for some special media containing rust impurities;
