There are various problems in the daily production and use of the buoy level gauge, and there are many matters needing attention when using it. The detection tube of the buoy level gauge is equipped with a set of reed switches and precision resistors. When the liquid level of the magnetic float outside the tube changes up and down, the dry reed located at the liquid level in the detection tube is turned on in turn to change the resistance value of the transmitter. So, let's take a look at the use and advantages of the buoy level gauge.

So, let's take a look at the use and advantages of the buoy level gauge.
As a flow measuring instrument, buoy level gauge will inevitably encounter inaccurate measurement in the process of use. In order to help everyone to use float level gauge for correct measurement in future work.
The correct use of buoy level gauge:
1. Install a stop valve between the liquid level of the measured container and the upper and lower liquid pipes. When the upper and lower stop valves are closed, open the drain flange at the bottom of the level gauge or remove the drain screw, and inject clean water to clean the level gauge body.
2. The verticality of the center line of the flange is 4. When the measuring range of the level gauge is greater than 3 meters, it is necessary to consider adding an intermediate reinforced flange as a fixed support to increase the strength.
3. The cross-sectional area of the core wire connecting the matching remote transmission liquid level transmitter and the secondary instrument shall be greater than 0.8 mm2. When laying in parallel with AC power supply on the same road, it should be laid separately at a distance of at least 20cm. For laying through iron pipes or with shielded double-core cables, only one end of the shielding layer can be grounded.
4. The liquid level controller is selected, and its contact capacity is designed as a resistive load. If an unimpeded or high-power load is used, an intermediate relay should be used for switching.
5, for the liquid medium containing suspended impurities and magnetic substances, it is not appropriate to use the liquid level gauge (because these impurities will cause the float assembly stuck)
6. The structure "L1" is the "sinking distance" of the side-mounted level gauge ". The user must understand this parameter. This parameter is related to the density of the medium. According to the principle of buoyancy, the length of the float assembly is related to the density of the medium. Therefore, when selecting and designing, it must be considered that different media have different L1.
The buoy level gauge has the following advantages:
1. Flexible installation, easy to use, simple effect, and can be displayed on site
2. Signal isolation amplification, cut-off interference design, strong anti-interference ability
3. Anti-condensation, anti-lightning, anti-corrosion and anti-clogging design
4. Probe diameter 19mm42mm optional
5. Reverse connection, overvoltage protection and current limiting protection
6, ultra-wide price range, easy to choose.
