Liquid Level Apparatus
Product Code : LSK-PL-10341
Liquid Level Apparatus (SKU LSK-PL-10341), a form of communicating vessels, shows that several connected bodies of water settle at the same height whatever their shapes. At an elementary level it demonstrates that pressure is transmitted equally through a liquid under gravity and air pressure; older students can use it for more advanced pressure ideas. The apparatus is a Science Lab Supplies product, manufactured at Plot 448, HSIIDC Industrial Area, Saha, Ambala, and priced for schools, colleges, tender contractors and distributors by the factory itself.
Specifications
The table lists each point about this equal-level apparatus on its own row. In short, it links several water bodies of different shapes so that they share one liquid; when water is poured in, every part settles to the same level, showing that liquid pressure depends on depth rather than on the shape of the container.

Applications and Experiments for the Liquid Level Apparatus
The apparatus answers a common student question: why does water in a wide vessel not push the level higher in a narrow one? Because pressure in a liquid depends only on depth, all connected parts reach one level. It suits primary, middle and secondary pressure lessons in school physics lab equipment in India.
- Primary and middle-school science: water finds its own level.
- NCERT Class 8 science, pressure: liquids exert pressure that depends on depth.
- Class 11 physics, mechanical properties of fluids: hydrostatic pressure and Pascal’s law, continued with loaded pistons on the Fluid Pressure Apparatus, Hydraulic Press.
- Everyday links such as water tanks and hose levels, and the same principle behind the U-Tube Manometer on Stand Table Model.
Standard Scope of Supply
The Liquid Level Apparatus is supplied as a single unit as described above. For the demonstration it is filled with water, which can be coloured to make the levels easier to see from the back of the class. Further fluid-pressure items can be added as separate lines on the quotation.
Packing, MOQ and Lead Time
You may request a price for one apparatus or for a batch covering several labs or schools. The quotation will state packing, delivery time and price for that quantity, and further fluid-pressure items can be combined on the same quotation to simplify ordering.
Registered as an exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Kenya, Ghana, Ethiopia, Tanzania, Uganda and the UAE. A pressure-lab list can be posted from the contact page or assembled in the enquiry cart, while procurement officers working to a tender can start from the lab tender page.
Frequently Asked Questions
What does the Liquid Level Apparatus prove?
That connected bodies of water come to rest at the same height regardless of their shapes, because pressure is transmitted equally through the liquid under gravity and air pressure.
Is it only for younger students?
No. It works as an elementary demonstration, and more advanced variations on liquid-pressure principles can also be explored with it in higher classes and college physics.
How does it differ from the Communication Vessel Apparatus?
Both show liquids finding a common level. The Communication Vessel Apparatus is a separate model with four glass pipes of different shapes on a common horizontal pipe and a 230 x 100 x 22 mm wooden base.
Where is the apparatus made?
On the Science Lab Supplies production floor in Saha, Ambala, India. Buyers deal with the manufacturer directly, and every quotation for the apparatus is issued from that factory.
