Level of magnetic flap profile:
    HN-UHZ-300 Series Magnetic turned column (Magnetic turned column) level gauge is based on magnetic coupling principle, the principle of communicating vessels, Archimedes (buoyancy) and other principles of a clever combination of the characteristics of mechanical drive and developed a level measurement device designed for.
    This type of instrument has a float receiving cavity (referred to as the main pipe or casing), which form a flange or other communication via the interface and the container; such that the liquid level within the chamber with the liquid level within the container is the same height, so the cavity will float with the liquid level in the container while lifting the lift; this time we installed a turned column display outside of the cavity, as we float in the manufacture of liquid in the sink float the junction portion of the installed floating magnet, when it float with the lift surface, it passes through the magnetic housing to turn column display, push turned column magnetic flip 180 °; the magnetic turned column is red, two semi-cylindrical white synthetic cylinder, flipped 180 ° so after the column turned toward the outside of the display will change color (below the surface of the red, white above), that is at the junction of the two-color liquid surface height.

HN-UHZ-300 magnetic level gauge
First, the principle and structure of work
    Magnetic turned column (Magnetic turned column) level gauge is based on the principle of magnetic coupling, Archimedes (buoyancy) and other principles of a clever combination of the characteristics of mechanical drive and developed a special means for level measurement.
    This type of instrument has a float receiving cavity (referred to as the main pipe or casing), which form a flange or other communication via the interface and the container; such that the liquid level within the chamber with the liquid level within the container is the same height, so the cavity will float with the liquid level in the container while lifting the lift; this time we can not see the liquid level, so we installed a turned column display outside of the cavity, because we manufacture the float in the float and sink into the liquid portion of the junction leak installed magnets, when it float with the lift surface, it passes through the magnetic housing to turn column display, push turned column magnetic flip 180 ° ; the magnetic turned column is red, white two semi-cylindrical synthetic cylinder, flipped 180 ° so after the column turned toward the outside of the display will change color (below the surface of the red, white above), that is at the junction of two color liquid surface height.
    Instruments with level transmitter (remote electrical signal), the level transmitter section (electrical part) works by using a magnetic float circuit connected to the role of lead resistance changes in the number of magnetic reed switch, and then, so that the sensor portion may occur due to changes in the level corresponding to the resistance signal. Through the signal converter, the resistance of the signal can be converted to the 4 ~ 20mA current signal. Electronic device of the present level gauge almost no capacitors, inductors and other energy storage components. Can be superimposed HART communication protocol, you can also use RS485 communication bus.

Second, product characteristics
    The gauge is based on similar products from home and abroad, and actively absorb, combines the advantages of many products through the company's technical staff of well-designed, high-quality magnets and imports of electronic components. Products are:
    Measuring range, intuitive readings clear;
    Sealing engagement less surface, easy to leakage, safe and reliable;
    Indicating portion completely isolated with the measured medium;
    Easy to install, easy maintenance.
