ULB –T150S glass level gauge is produced basing on the principle of communicating vessels for on-site indicating instrument, the instrument will be introduced medium within the container inside itself, and through the transparent glass to read the actual height of the liquid level. Instrument built with safety valve ball up and down, so when the glass was accidentally destroyed, under the pressure of container, ball automatically turns off the liquid flow channel to avoid excessive liquid leakage.

These level gauges are particularly suitable for liquids:

- colourless
- very fluid
- non-corrosive for glasses

Working principle

It is a variation of transparent level gauges, however equipped with two glasses with groove , fitted with suitable coloured filters. The sharp reading is given by the contrast between the bright colour of filters in the lower part containing liquid and the colour of upper part of visible window.


Continuous level indication without power supply.
Direct indication of the level.
Individual design and corrosion resistant materials make the products suitable for a broad range of applications.
Chemical, petrochemical industry, oil and natural gas extraction(on-and offshore),shipbuilding, machine building, power generating equipment, power plants.
Oil and gas, heat transfer and refrigeration systems, plants for cryogenics.


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 colour.

- 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.
