T-SERIES TRANSPARENT LEVEL GAUGES

This type of indicators display the level of the fluid through a transparent surface, being part of a column that is connected to the vessel by on-off cock gauges. They are composed of one or more opposed pairs from smooth borosilicate glass (crystal) that are tightened inside a steel box. The level reading is based on a different transparency of the fluid and the gas or vapour. In heavy-duty applications, the glass is protected by means of a mica shield, which however reduces the reading transparency. To remedy this phenomenon, special illuminators are used which exploit the total refraction / reflection effect in the fluid / gas or vapour separation surface.

Transparent indicators are successfully used up to 250 bars and with media temperatures from -196 °C up to +427 °C.

APPLICATIONS AND TECHNICAL DATA

Transparent level indicators are used in various industrial processes,

especially in the chemical, petrochemical, power production, metal and

steel, water treatment, food, paper industries and the like.

They are used to carry out surveys on clear or dirty, viscous or corrosive

fluids, consistent with the protective transparent material.

Versions with body and wetted parts in galvanized Carbon Steel are

available, whereas AISI 316, ASTM A350 LF2, Hastelloy and other materials

are available upon request.

The standard versions feature the following rating:

- PN 40 (mod. TBB)
