Jinhu Hongchuang UZ type magnetic flap liquid level meter

The
type magnetic flap level gauge can also be called a magnetic float level gauge, which is developed based on the principle of buoyancy and magnetic coupling. When the liquid level in the measured container rises and falls, the magnetic float in the body tube of the liquid level gauge also rises and falls. The permanent magnet in the float is transmitted to the magnetic flip column indicator through magnetic coupling, driving the red and white flip column to flip. When the liquid level rises, the flip column changes from white to red. When the liquid level drops, the flip column changes from red to white. The red and white junction of the indicator is the actual height of the liquid level inside the container, thus achieving a clear indication of the liquid level. It can be used for local display or remote display and control of liquid level in high-temperature, explosion-proof and anti-corrosion food and beverages and other occasions.
This series of products can achieve high sealing and leakage prevention and can safely and reliably measure liquid level under high temperature, high pressure, high viscosity and strong corrosive conditions. The whole process of measurement has no blind areas. The display is eye-catching, the reading is intuitive, and the measurement range is large. It is equipped with liquid The level alarm control switch can realize upper and lower limit alarm and control of liquid level or interface level. It can be equipped with a liquid level transmitter to monitor the liquid level. The interface signal is converted into a two-wire standard signal to realize remote detection, indication, recording and control. The series of magnetic flap liquid level meters are widely used for liquid level measurement and control in the production process of electric power, petrochemical, metallurgy, environmental protection, shipbuilding, food and other industries.

Structure and working principle
Basic type
According to the principle of buoyancy, the float follows the liquid in the measuring tube When the liquid level rises and falls, the permanent magnet in the float drives the red and white flipping column to flip. When the liquid level rises, the flipping column turns from white to red, and when it falls, the flipping column turns from red to white, thereby achieving liquid level indication.
Electric remote transmission
A transmitter is installed on the float level gauge. The float moves up and down, and the measuring elements in the guide rod act sequentially through magnetic coupling to obtain the change in resistance signal and convert it into a standard of or Signal output, connected with display instrument or computer to achieve remote transmission purpose.
Upper and lower limit switch output
A controller is installed at the upper and lower limit positions set by the user on the liquid level meter riser. The controller has a self-maintaining reed switch and uses a magnetic float to move with the liquid level. When the reed switch is activated, alarm or limit control is achieved.
System composition and wiring
Upper and lower limit switch output
It is composed of a reed switch and a converter with self-maintaining function. The reed switch and converter are installed on site and in the control room respectively. The device provides three pairs of contact switches.
Electrical remote transmission
It consists of two parts: the measurement unit and the transmission unit.
Intrinsically safe explosion-proof
With intrinsically safe explosion-proof, upper and lower limit switch output type
The explosion-proof switch consists of a reed switch and a safety barrier with relay contacts, which can directly provide the user with a pair of normally open or normally closed contact. If users need more contacts, special designs and orders can be made. Figure 3
Intrinsically safe explosion-proof remote transmission type
Suitable for use in factory-grade gases similar to electrical equipment, with a maximum surface temperature group of ℃. Figure 4
Precautions for use
① The transmitter housing is equipped with an external ground, and the user must ground it reliably when using it.
② The use of the safety barrier should comply with the relevant instructions for use.
③The connecting cable between the transmitter and the intrinsically safe end of the safety barrier is a two-core shielded cable. The cross-sectional area of the core wire > the allowable distributed capacitance of the cable is
