Specific Parameters |
Value / Description |

Measurement Principle |
The HNL90-A magnetic float level gauge is installed on the extension pipe on the outside of the tank. The liquid level inside the tank can be clearly seen from the float indicator. A magnetic switch can also be installed on the outside of the bypass pipe as an electrical contact signal output, or a level transmitter can be installed for long-distance liquid level signal transmission and liquid level control. An extension pipe is installed on the outside of the tank, and a level indicator is installed on the outside of the bypass pipe. A float containing a magnet is placed in the bypass pipe. Because the magnetic color plate contains a magnet with the opposite magnetism to the float, when the float rises, it will attract the magnetic color plate, causing the color of the magnetic color plate to flip from white to red, indicating the actual liquid level height. |
