Product Description:
The significant feature of anti-corrosion 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 the choice for measuring the liquid level of highly corrosive media such as hydrofluoric acid. Tailored for customers with low temperature and pressure requirements, our PP material level gauge can be used.
The stainless steel lined PTFE corrosion-resistant 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 a new process of stainless steel lined PTFE stretching and flanging, with a reliable structure and long service life. It is the choice for measuring the liquid level of highly corrosive media such as hydrofluoric acid.
The side mounted 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 insulation properties of PPR, this product is suitable for outdoor water tank level measurement. It will not freeze inside in winter, but its temperature and pressure resistance are not as good as PTFE lined type. When the temperature and pressure are low, this product has a higher cost-effectiveness. 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.
Characteristics of anti-corrosion magnetic flap 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.
Installation and maintenance of anti-corrosion magnetic flap 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.
