Venturimeter Test Rig Manufacturer,Supplier and Exporter in India
Product Code : EL-DSO-10353
Jlab Export is a leading Venturimeter Test Rig Manufacturer,and suppliers in India
Venturimeter Test Rig (code EL-DSO-10353) is a fluid mechanics bench for determining the coefficient of discharge of a venturimeter. The venturimeter is made of clear acrylic, so the converging inlet, throat and diverging outlet can be seen while water flows, and the rig carries its own pump, sump and measuring tank on an angle iron frame. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Venturimeter Set-ups?
| Set-up | Flow meters | Pipe lines | Tanks |
|---|---|---|---|
| This rig (EL-DSO-10353) | One clear acrylic venturimeter, 25 mm ID, 13 mm throat | GI piping with flow-control and bypass valves | Measuring tank 300 x 300 x 300 mm; sump 600 x 300 x 300 mm |
| Venturimeter and Orificemeter Calibration Set-Up | Clear acrylic venturimeter and orificemeter, each for 1-inch pipe, connected in parallel | Two pipelines from a common manifold | Measuring tank 25 litres; sump 50 litres |
| Venturi meter and Orifice Meter Apparatus | Venturi meter and orifice meter of 25 mm size | Two GI pipe lines with gate valves and a distribution chamber with isolating cocks | Sump with 0.5 HP pump |
Choose this rig when the practical is the calibration of a single venturimeter; the other two set-ups carry an orifice meter as well, so the two meters can be compared on one bench.
What Is the Venturimeter Test Rig Used For?
A venturimeter narrows the flow from the inlet diameter to a throat and then widens it again. By continuity the water speeds up in the throat and, by Bernoulli’s equation, its pressure falls; the head difference h between inlet and throat, read on the differential manometer, gives the theoretical discharge a1a2√(2gh)/√(a1² − a2²). Dividing the actual discharge, found by timed collection in the measuring tank, by this value gives the coefficient of discharge, which students plot against flow rate. Calibrating flow meters in this way is a standard practical in the fluid mechanics labs of civil, mechanical and chemical engineering courses.
What to Specify When Ordering
- Number of rigs for the lab.
- Electrical supply — the 0.5 HP pump runs on single-phase 220 V AC, 50 Hz.
- Companion flow benches, such as the orifice or Pitot tube set-ups linked below, which are separate items.
Frequently Asked Questions
What are the venturimeter’s dimensions?
It is a clear acrylic conduit measuring 75 x 75 x 250 mm, with a 25 mm inner diameter and a 13 mm diameter at the throat.
How is the pressure difference measured?
With a 50 cm U-tube differential manometer connected across the venturimeter.
What are the tanks and piping made of?
The measuring and sump tanks are SS 304 sheet, and the piping and fittings are GI.
What should an export quotation request include?
The number of rigs, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), packing or labelling needs and any tender reference.
Who manufactures the Venturimeter Test Rig?
JLab (Jain Laboratory Instruments Pvt Ltd) builds it at its own works in Ambala, Haryana, and quotes for it as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of hydraulics and fluid mechanics lab equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The rig is fabricated at JLab’s own works rather than bought from a trader, so engineering colleges, polytechnics, dealers and importers buy it factory-direct, each rig is visually inspected before dispatch, and repeat orders are handled by the maker. JLab exports worldwide and ships to buyers in every region — for example Mongolia in East Asia, Luxembourg in Western Europe, Senegal in West Africa, Kuwait in the Middle East and Zimbabwe in East Africa. Tender details are on the JLab lab tenders page.
