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 convergent-throat design, standard textbook equations give the flow rate accurately from the measured pressures. Every unit comes from the Science Lab Supplies factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, where the company manufactures it for sale direct to engineering institutions, tender contractors and distributors.
Specifications
The module is a Venturi meter that quickly fits between the adaptors in the base unit of the Flow Meter Calibration apparatus. 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 the meter causes.

Applications and Experiments for the Venturi Flowmeter
The meter is used to calculate flow rate from the pressure drop between the inlet and the throat, to compare that result with the actual flow and to find how much pressure is lost overall. It suits fluid mechanics lab experiments in B.E./B.Tech and diploma courses on flow measurement.
- 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.
- Comparing the Venturi with the nozzle meter on the same base unit.
- Diploma courses: permanent pressure loss of differential flow meters.
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. The contact page, enquiry cart and lab tender page are the three routes for requesting a price.
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 across it.
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.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. The Venturi meter is produced at its plant in Saha, Ambala, India, and enquiries are priced by the factory itself.
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.
Related Venturi and Flow Meter Equipment
The base unit and Pitot module below complete the flow meter comparison, while the Bernoulli and cavitation rigs take the Venturi further: one maps pressure along the whole convergent-divergent passage, the other shows what happens when throat pressure falls too low. All four can be quoted together.
