Working Principle

 

The Magnetic level gauge operates based on the communicating vessels principle, Archimedes' buoyancy principle, and magnetic coupling effect. When the liquid level in the measured container changes, the magnetic float inside the main tube floats up and down accordingly. The permanent magnet inside the float transmits signals to the external Magnetic level Indicator through magnetic lines of force. The flap indicator is composed of red and white bi-color magnetic flip columns. When the tank liquid level rises, the flip columns change from white to red; when the liquid level drops, they change from red to white. The boundary between red and white is the actual position of the current liquid level, enabling intuitive liquid level display.

 

 

Application Scenarios

 

Thanks to its high precision, strong adaptability, and reliable safety features, the Magnetic level gauge has a wide application usages as followings:

 

Petrochemical Industry: the Magnetic level gauge can be used in the liquid level measurement of oil storage tanks, reactors and pipelines,etc, it can withstand high temperature, high pressure and corrosive media (such as acid, alkali, oil and gas).

Due to its explosion-proof features, the magnetic level gauge can also be used for the flammable and explosive environments such as refineries and chemical plants.

 

Food and beverage industry: the Magnetic level gauge adopts the food-grade stainless steel construction, which making it perfect to meet the strict hygiene standards. whatever it's monitoring fruit juices, dairy products, or soy sauce during production, its simple structure makes cleaning and upkeep a breeze-exactly what's needed in an industry where cleanliness is non-negotiable.​

 

Pharmaceutical Industry: As the High precision and aseptic design, the Magnetic Level Gauge is also suitable for links such as liquid medicine storage and proportioning, ensuring the quality and safety of pharmaceutical production. It can be equipped with remote transmission function to realize automatic control and improve production efficiency. (In some cases, Magnetostrictive Level Gauge is also used here for more precise measurement)

 

Environmental Protection and Water Treatment: Used for liquid level monitoring of sewage pools and wastewater treatment equipment. Plastic or lined materials can resist sewage corrosion. Frost-proof and heat-preserving designs are suitable for measuring low-temperature or high-viscosity liquids, preventing media from freezing or solidifying.

 

Power and Energy Industry: Monitors boiler water level and condensate tank liquid level. The remote transmission type supports centralized control in power plants. The high-pressure type can withstand 32MPa pressure, suitable for high-pressure containers in the power industry.

 

Other Industries:

 

Water conservancy: the Magnetic level gauge could also Monitor the water levels of reservoirs and rivers, to provide the data support for flood control and drought resistance.

 

Construction: Measuring liquid levels of underground storage tanks and spherical containers.

 

Shipping: Indicating liquid levels of marine fuel tanks and ballast water tanks.

 

Ziasiot Magnetic Level Gauge

 

Compared with traditional glass tube and plate level gauges, it has higher reliability, safety, advancement, and practicality. The most notable feature of the side-mounted Magnetic level gauge is that the liquid medium is completely isolated from the Magnetic level Indicator, so it is very safe, reliable, and durable under any circumstances. Moreover, various types of level gauges can be equipped with liquid level alarm and control switches to realize over-limit alarm, control, or interlock of liquid level or interface. Equipped with a static pressure level transmitter or a reed-resistor level transmitter, it can convert the liquid level or interface signal into a two-wire 4-20mADC standard signal, realizing remote indication, detection, recording, and control.
