Frost Proof Glass Plate Level Gauge - ULB-FS

ULB-FS Frost-proof Glass Plate Liquid Level Gauge

Summary

During liquid level measurement, when the medium’s temperature is lower than 0 C, it can make vessel’s surface frost so that frost layer covers vessel’s surface including the Gauge’s glass plate. Therefore, it is not possible to use a common liquid level Gauge to measure such low temperature medium. The frost-proof glass plate liquid level Gauge is designed specially for low temperature medium level measurement. The medium’s level can be viewed clearly through frost-proof fin.

Structure principle

According to temperature gradient principle, when there is one kind of temperature delivering material to connect low temperature source, more farther away is the material from the low temperature source, more closer is the temperature to the ambient temperature, which can resolve the level reading problem. This kind of Gauge is designed just on base of this principle. The low temperature medium level can be read out on the frost-proof fin.

Application notice

When the bolts loosing appears during the process of transportation, all the bolts should be tightened according to actual situation.

When checking or installing the glass plates, bolts should be tightened in order and cross way. Exerting force evenly.

When glass plates are needed to be changed, sealing plates should be changed together.
