The top-loading magnetic flap level gauge is one of the installation forms of the magnetic flap level gauge, and belongs to the field display level gauge product. Suitable for special installation environments such as underground storage tanks. Like the ordinary magnetic flap level gauge, it can support the remote signal function. The top loading magnetic flap level gauge is composed of indicator panel, float ball, connecting rod, etc., and the remote transmission type plus a remote transmitter.

Because of its relatively special installation method, it is different from the side-mounted type. For example, the top-mounted connecting flange will be larger than the side-mounted type, and the standard is DN150. As shown in the above figure, the float moves with the surface of the liquid, and the magnetic element of the upper end is pushed up and down by the middle link. The magnetic element drives the magnetic flap on the indicator panel to indicate the real-time height of the liquid surface. Red, no liquid shows white. The measurement principle is simple but the most intuitive and reliable, so the magnetic flap level gauge occupies a very important position in the market.
The top loading magnetic flap level gauge should pay attention to the following points during installation:
1. The working pressure should not be higher than 4.0Mpa, the temperature should not exceed 250°C, and the working environment temperature should not exceed 120°C.
2, the top-mounted length does not exceed 5 meters, in order to facilitate the installation and maintenance work.
3. There is a certain blind zone in the level gauge (compensated)
4. The body of the level gauge must be perpendicular to the horizontal plane, otherwise it will affect the measurement effect and the accuracy of the data.
5. The connecting rod inside the level gauge must not be bent.
6. After the installation is complete, it must be done again to ensure the accuracy of the readings.
7. Remote transmission type When fixing the sensor transmitter, care should be taken not to use ferrous materials.
8. Pay attention to the steps during debugging. The medium should be introduced slowly, otherwise it will easily cause impact on the float and cause damage to the body.
9. Remote transmission type In the selection of transmission cable, it is necessary to pay attention to shielding the two-core cable or adding a protection tube to the signal cable.
