UHZ-111/S anti frost magnetic float level gauge is a patented product designed specifically to solve the problem of external icing for low-temperature liquid level gauges. It differs from the figure on the right in that it does not have an insulated steam interface flange, and the insulation jacket contains a vacuum layer, which can effectively isolate cold and heat conduction, ensuring that the main tube of the liquid level gauge will not freeze or frost, thus ensuring the normal use of the liquid level gauge.
