Made by mayante Upper and lower limit of alarm magnetic level gauge Alarm and liquid level control are two basic parts. UHZ type magnetic flap level gauge is intuitive, eye-catching, cost-effective, temperature resistant, pressure resistant, anti-corrosion, explosion-proof characteristics, so that it is widely used in power, petroleum, chemical, metallurgy, environmental protection and other industries in the production process of liquid level measurement and automatic control.
Principle of magnetic level gauge with upper and lower limit alarm
Based on buoyancy principle and magnetic coupling effect, the upper and lower limit alarm magnetic level gauge produced by meiante company is developed. When the liquid level in the measured vessel rises or falls, the float in the main tube of the liquid level gauge rises and falls. The permanent magnetic steel in the float is transmitted to the field indicator through magnetic coupling to drive the red and white column to turn 180 degrees. When the liquid level rises, the turnover column turns from white to red. When the liquid level drops, the turning column turns from red to white. The red and white boundary of the indicator is the medium level in the container The actual height, so as to realize the liquid level indication.
According to the liquid level alarm and alarm value of Amtek, the liquid level can be controlled by the liquid level switch of Amtek.

Characteristics of high and low alarm magnetic level gauge
It is suitable for the measurement of liquid level and boundary position of pressure vessels, and can be used for on-site indication and control alarm.
The indication is novel and the reading is intuitive and eye-catching. The observation angle can be changed according to the user's convenience.
The measurement range is large, not limited by the height of the tank.
The indicating mechanism is completely isolated from the measured medium, so it is well sealed, highly reliable and safe to use.
High temperature resistant, can use colorless ceramic turnover column.
It is simple in structure and low in maintenance.
