Self-Regulating Siphon
Product Code : LSK-FM-10442
Self-Regulating Siphon (SKU LSK-FM-10442) is a clear acrylic hydraulic model that shows a siphon automatically adjusting its discharge over a wide range while the water level upstream stays mostly constant. Because the siphon passes a mixture of air and water, students can watch how it regulates itself. It is used in open channel and hydraulic structures practicals for engineering students. Science Lab Supplies manufactures the model in Saha, Ambala, India, at Plot 448, HSIIDC Industrial Area, and quotes it directly to colleges, contractors and distributors.
Specifications
The siphon is made from clear acrylic, so the air and water mixture passing through it is visible throughout. As the incoming flow changes, the proportion of air drawn in changes too, and the discharge adjusts automatically while the upstream level remains close to constant.

Applications and Experiments for the Self-Regulating Siphon
Students vary the flow reaching the siphon and record the discharge and the upstream level, showing that the level barely moves while discharge follows the supply. The model explains how siphon spillways hold reservoir and canal levels without gates or moving parts.
- B.Tech / B.E. civil engineering: siphon spillways and automatic level control.
- Recording discharge against upstream head for a self-regulating structure.
- Diploma irrigation courses: air-regulated siphons in canal systems.
Standard Scope of Supply
The Self-Regulating Siphon is supplied as a single unit as described above, made in clear acrylic. The flow channel or water supply it is tested with is not part of this item, and any optional accessories are listed on the quotation.
Packing, MOQ and Lead Time
A quotation is available for one siphon or for a set of open channel models, stating the packing, delivery time and price for your quantity. Other fluid mechanics lab experiments from the same range can share the quotation.

Frequently Asked Questions
How does a self-regulating siphon work?
It passes a mixture of air and water. As the flow changes, the amount of air drawn in changes, so the discharge adjusts itself while the upstream water level stays mostly constant.
Why is the model made of clear acrylic?
Clear acrylic lets students see the air and water mixture inside the siphon and follow how the flow pattern changes as discharge rises or falls.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturing company behind this model. It is produced in Saha, Ambala, India, and customers receive their price from the factory directly.
Can it be ordered with other channel models?
Yes. Gates, weirs, spillways and culverts from the same range can be listed together for a single quotation and consignment.
