ULB –R150L are designed to give an accurate liquid level reading of liquids that have a tendency to surge or boil. When the liquid being gauged has an usually low boiling point, the gauge and valves should be insulated and the gauge equipped with non-frosting unit. ULB –T150L are of flat glass reflex or transparent design. The liquid chambers is constructed of heavy tubing, rustproofed and carefully slotted and machined to provide plain seats for the gaskets and glass assemblies.

Working principle

Transparent level gauges are always fitted with two plate transparent glasses between which the fluid is contained. The fluid level is indicated as the result of the different transparency of the two media and in some cases, by conveying upwards on to the surface of separation (between liquid and gaseous substances) a source of light located at the back of the gauge.


- Reducing the boiling effects of entrained gas being released under lowered pressure;
- The liquid itself being vaporized when pressure reaches a critical low point;
- Boiling caused by temperature exceeding the boiling point of liquid.


Transparent level gauges are suitable for almost all installations.

In fact they permit:

- the use of mica shields to protect the glass form the corrosive action of the process fluid;

- the observation of interface

- the observation of the liquid color.

- can be used as a reference to check, or calibrate, other level technologies.

- Not affected by the chemical or electrical properties of the process liquid. Specific gravity, dielectric, conductivity, surface turbulence, vapor, foam, etc. no longer needs to be considered.


The main body of the sight glass level gauge, contains the liquid channel.
For the clamping of the sight glass plate
Flat gasket
Chambered sealing between the liquid channel and the environment
Sight glass plates per QB2112
Mechanical protection between cover and glass
Bolt, nut
Hold the forces form the internal pressure
Glass size
Standard lengths of sight glass plates per QB2112, width 34 mm, thickness 17 mm
Valve heads
Valve heads isolate the vessel from the sight glass level indicator. They consist of the valve body and the head piece. They are actuated by a valve with quick closing lever or hand-wheel. In general, they are fitted with a ball-check valve as a safety element.
Ball-check valve
The ball-check valve should prevent any major spillage from the sight glass level indicator in the event of any glass or mica breakage or other sizable leakge. For this purpose there is, under the valve seat(pressure>0.5bar).in this way, the flow is sharply reduced. The closing of the valve presses the ball back into its starting position.
