Anti corrosion magnetic flap level gauge

Anti corrosion magnetic flap level gaugeThe significant feature of the concentrated sulfuric acid level gauge is that the liquid medium is isolated from the indicator, making it very safe, reliable, and durable in any situation. Various models of level gauges are equipped with level alarms and control switches, which can achieve upper and lower limit alarm, control, or interlocking of the liquid level or boundary. When equipped with static pressure level transmitters or dry spring resistance level transmitters, the liquid level and boundary signals can be converted into two-wire 4-20mADC standard signals, realizing remote indication, detection, recording, and control. Suitable for liquid level measurement in corrosive media and high operating temperatures, with reliable structure and long service life. It is a good choice for measuring the liquid level of highly corrosive media such as sulfuric acid. Tailored for customers with low temperature and pressure requirements, our PP material level gauge can be used.

Users can use remote transmitters according to engineering needs, which can achieve local digital display and output standard remote transmission electrical signals of 4-20mA to meet the needs of recording instruments or industrial process control. It can also be used in conjunction with magnetic control switches or proximity switches to monitor liquid level alarms or control inlet and outlet equipment.
The sulfuric acid tank 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 a new process of stainless steel lined PTFE stretching and flanging, with reliable structure and long service life. It is the best choice for measuring the liquid level of highly corrosive media.
The sulfuric acid tank level gauge 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 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. Users can use remote transmitters according to engineering needs, which can achieve local digital display and output standard remote transmission electrical signals of 4-20mA to meet the needs of recording instruments or industrial process control. It can also be used in conjunction with magnetic control switches or proximity switches to monitor liquid level alarms or control inlet and outlet equipment.

2、 Characteristics of concentrated sulfuric acid 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 concentrated sulfuric acid level gauge
1. The installation of the liquid level gauge must be vertical to ensure that the float component can move freely up and down inside the main pipe.
2. Magnetic conductors are not allowed to approach the main body of the liquid level gauge, otherwise it will directly affect the correct operation of the liquid level gauge.
3. After the installation of the liquid level gauge is completed, it needs to be calibrated with magnetic steel to guide the flip column once, so that the display below the zero position is red and the display above the zero position is white.
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、 Application and scope of concentrated sulfuric acid level gauge:

6、 Thick Sulfuric acid level gauge model and description:

Structure and working principle of sulfuric acid tank level gauge:

The product uses a magnetic float as the measuring element. According to the principle of buoyancy, the magnetic float moves up and down in the measuring tube with the rise and fall of the liquid level. The magnetic steel inside the magnetic float drives the red and white flip columns to flip 180 ° through coupling. When the liquid level rises, the flip column changes from white to red, and when it falls, it changes from red to white (flip column display, no energy required), thus achieving liquid level indication.
1. Basic type
According to the principle of buoyancy, the float in the measuring tube moves up and down with the rise and fall of the liquid level. The magnetic steel inside the float drives the red and white flip columns to flip 180 degrees through magnetic coupling. When the liquid level rises, the flip column changes from white to red, and when it falls, it changes from red to white, thus achieving the indication of the liquid level.
2. Equipped with upper and lower limit alarm switch point magnetic flap level gauge
By using a magnetic float to move with the liquid level, the switch installed at the set position of the liquid level gauge riser can be activated to achieve on-off control or alarm.
3. 4-20mA electric remote transmission
Install a transmitter on the magnetic float level gauge. The transmitter consists of two parts: a sensor and a converter. It moves up and down through a magnetic float and uses magnetic coupling to sequentially move the measuring elements inside the conduit, obtaining changes in resistance signals and outputting standard current signals of 0-10 or 4-20mA for connection with digital display instruments or computers to achieve remote display and control.
