Sulfuric acid level gauge

The significant feature of concentrated sulfuric acid level gauges is that the liquid medium is completely isolated from the indicator, making them 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.

Manufacturer's price:

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.

1、 Difference in lining selection for concentrated sulfuric acid level gauge:

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 a good choice for measuring the liquid level of highly corrosive media such as sulfuric 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 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 level gauge, otherwise it will directly affect the correct operation of the 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.

6、 Thick Sulfuric acid level gauge model and description:

A brief introduction to sulfuric acid level gauge:

Phenol level gauges can be used for medium level detection in various equipment such as towers, tanks, tanks, spherical vessels, and boilers. This series of liquid level gauges can achieve high sealing, leak prevention, and are suitable for high temperature, high pressure, and corrosion-resistant applications. It compensates for the defects of poor clarity and easy breakage of glass plate (tube) level gauges, and the entire measurement process has no blind spots, clear display, and a large measurement range. The components of the magnetic flap level gauge are made of materials such as 1Cr18Ni9Ti, 316L, 0Cr18Ni9Ti, 1Cr18Ni9Ti lined with PTFE (polytetrafluoroethylene), PVC, PP, and imported components, which have high reliability and corrosion resistance.

Overview of sulfuric acid level gauge:

The sulfuric acid level gauge is an internal float type level gauge developed by our company based on the long-term production of plate and tube level gauges and the adoption of new foreign technologies. Due to the use of stainless steel materials for its pressure bearing parts, the sealing joint surface is reduced in structure, thus improving the safety and reliability of the instrument. The liquid level display is clear and eye-catching.

Principle of sulfuric acid level gauge:

The sulfuric acid level gauge consists of a body (composed of upper and lower conduits), a flip box (composed of red and white dual color magnetic flip plates), a float (composed of a magnet, a top rod, and a float), etc. The working principle is that the float in the container (developed according to different media and pressures) floats up and down in the lower conduit with the change of liquid level height, and the magnet moves up and down in the upper conduit through the top rod, causing the outer flip plate to flip and indicating the liquid level height with red and white colors.

Parameters of sulfuric acid level gauge:

1. Measurement range (center to center distance between upper and lower flanges): L=500-6000mm, special orders can be placed for sizes exceeding 6000mm;
2. Indication error: ± 10mm;
3. Work pressure: Normal type: ≤ 6.3MPA, High pressure type: 6.3-16MPA;
4. Medium temperature: ordinary type: ≤ 150 degrees, high temperature type: 150-450 degrees;
5. Medium density: ≥ 0.45g/m ³;
6. Density difference: ≥ 0.15g/m ³ (measurement interface);
7. Liquid receiving material: Standard 1Cr18Ni9Ti. Different grades of stainless steel such as 304, 316, 316L, 316Ti, 317, 317L, S2205, Ti, etc. can be selected according to the chemical properties of the tested medium to achieve anti-corrosion purposes;
8. Connection flange specifications: DN20, DN25, special specifications require customization.

Characteristics of sulfuric acid level gauge:

1. When the side opening of the container is not suitable and there is little space around the container, this type of liquid level gauge can be installed on the upper or lower part of the container

2. Suitable for liquid media with high viscosity

3. The viewing direction of the monitor can be changed arbitrarily

4. Install liquid level switch transmitter and control switch, which can be installed and adjusted at any time without stopping the machine.
