Sodium hydroxide level gauge

The specialized level gauge for sodium hydroxide storage tanks uses a magnetic float as the measuring element and a magnetic steel driven flip column display, without the need for 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 dedicated level gauge for sodium hydroxide storage tanks uses a level gauge controller, and its contact capacity is designed for resistive loads. If non resistive or high efficiency loads are used, intermediate relays must be used for conversion. For situations where liquid media contain suspended impurities and magnetic substances, it is not advisable to use the "sinking distance" parameter of the side mounted magnetic flap level gauge. Users must be aware of this parameter. This parameter is related to the density of the medium. According to the principle of buoyancy, the length of the float component is related to the density of the medium. Therefore, when selecting and designing, it is necessary to consider that different media have different sinking distances.

Specification parameters:

The magnetic flap level gauge is a device specially developed for level measurement based on the principles of magnetism, Archimedes' law of buoyancy, and other principles combined with the characteristics of mechanical transmission. The side mounted magnetic flap level gauge uses a magnetic float as the measuring element and a magnetic steel driven flip column display, without the need for 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.
Structure principle of sodium hydroxide level gauge:
Developed based on the principle 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 degrees. When the liquid level rises, the flip column changes from white to red, and when the liquid level drops, the flip column 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 significant feature is that the liquid medium is completely isolated from the indicator, making it very safe, reliable, and durable in any situation. Moreover, various models of liquid level gauges are equipped with liquid level alarms and control switches, which can achieve upper and lower limit over limit alarms, control, or interlocking of liquid levels or boundaries; Equipped with a static pressure level transmitter or a dry spring resistance level transmitter, the liquid level and boundary signals can be converted into a two-wire 4-20mADC standard signal, enabling remote indication, detection, recording, and control. This series of magnetic flap level gauges can be widely used for level measurement and control in various industries such as power, petroleum, chemical metallurgy, environmental protection, shipbuilding, construction, and food production processes.
Overview of Sodium Hydroxide Level Gauge Products:
It can be used for medium level detection of various towers, tanks, spherical containers, boilers and other equipment. It can achieve high sealing, leak prevention, and adapt to liquid level measurement under high pressure, high temperature, and corrosive conditions, with reliable safety. It compensates for the shortcomings of glass plate (tube) liquid level gauges, such as unclear indication and easy breakage, and is not affected by high and low temperature fluctuations. It does not require the combination of multiple sets of liquid level gauges.
The entire measurement process has no blind spots, with clear display, intuitive readings, and a large measurement range. Especially in the on-site indication section, as it does not come into direct contact with liquid media, its superiority is even more evident for high temperature, high pressure, high viscosity, toxic and harmful, and highly corrosive media. Therefore, it is more reliable, safe, progressiveness and practical than the traditional glass tube and plate level gauge.
