Venturi Flowmeter
Product Code : LSK-FM-10453
Venturi Flowmeter (SKU LSK-FM-10453) is a Venturi meter module for the Flow Meter Calibration unit that shows students the accuracy and use of this classic flow meter. Because of its specific design, standard textbook equations give the flow rate accurately from the measured pressures. The module is a Science Lab Supplies product, manufactured in the company's Saha, Ambala factory (Plot 448, HSIIDC Industrial Area, India) and offered direct to engineering institutions, tender contractors and distributors.
Specifications
The Venturi module's details are set out row by row in the table. In short, the meter fits quickly between the adaptors in the base unit of the Flow Meter Calibration apparatus, and the calibration unit's manometers then show the pressure difference at the meter and across the overall meter assembly, giving both the flow reading and the loss.

Applications and Experiments for the Venturi Flowmeter
With this meter, flow rate can be calculated from the pressure difference read at the Venturi, compared with the actual flow and checked for the overall pressure lost across the assembly. It suits fluid mechanics lab experiments in B.E./B.Tech and diploma courses on flow measurement and the energy equation.
- B.E./B.Tech mechanical and civil: determining the coefficient of discharge of a Venturi meter.
- Applying the continuity and Bernoulli equations to a real meter, then following the pressure along a full acrylic convergent-divergent section on the Bernoullis Theorem Complete with Collecting Tank.
- Comparing the Venturi with the nozzle meter on the same base unit.
- Diploma courses: permanent pressure loss of differential flow meters, and low throat pressure shown on the clear acrylic Venturi of the Cavitation Demonstration.
Standard Scope of Supply
The Venturi Flowmeter is supplied as a single meter module, ready to fit between the adaptors of the calibration base unit. The Flow Meter Calibration apparatus, with its manometers and hand-pump, is a separate product; any optional accessories are named on the quotation.
Packing, MOQ and Lead Time
You can ask for one module to extend an existing calibration unit, or for complete sets for several student groups. The quotation states the packing, delivery time and price for that quantity, and other engineering lab equipment in India from the fluid mechanics range can be added to it.
Registered as an exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Ethiopia, Tanzania, Uganda, the UAE, Saudi Arabia and Oman. A Venturi module can be requested with a short note on the contact page or added to the enquiry cart beside other meters, while public-sector buyers will find the bid process on the lab tender page.
Frequently Asked Questions
Does the Venturi Flowmeter work on its own?
No. It is a module for the Flow Meter Calibration unit: it fits between the base-unit adaptors, and the unit's manometers read the pressures at the meter and across the whole meter assembly.
Why is a Venturi meter used in teaching labs?
Its specific design means standard textbook equations predict the flow accurately from the measured pressures, so students can compare theory and measurement with confidence on a single flow meter.
Is Science Lab Supplies the manufacturer or a trader?
Production of this Venturi module takes place in Science Lab Supplies' own factory in Saha, Ambala, India, and the same company prepares the quotation, so your enquiry is answered by the maker itself rather than a distributor.
How does it differ from the Bernoulli's Theorem apparatus?
This module is a flow meter read by the calibration unit's manometers. The Bernoulli's Theorem apparatus is a separate Venturi with many more tappings to water manometers, for full study of the pressure distribution.
