Flow Meter Demonstration
Product Code : LSK-HAP-10579
Flow Meter Demonstration (SKU LSK-HAP-10579) is a bench-top accessory that places a venturi meter, a variable area meter and an orifice plate in series so students can compare three common flow meters on the same flow. It is used in fluid mechanics labs of engineering colleges, polytechnics and TVET institutes. It is manufactured by Science Lab Supplies in the HSIIDC Industrial Area at Saha, Ambala, India (Plot 448), and the company supplies it without intermediaries to colleges, tender contractors and distributors.
Specifications
Each part of the three-meter flow demonstration is listed separately in the table. In short, a venturi meter, variable area meter and orifice plate sit in series on a support frame over the hydraulics bench, with tappings to an eight-tube manometer bank that has a manifold, air bleed valve and hand pump.

Applications and Experiments for the Flow Meter Demonstration
With all three meters on one line, each reading can be checked against the bench’s volumetric tank and against the other meters at the same moment. That makes the unit a compact way to teach flow measurement and head loss in fluid mechanics lab experiments for B.Tech, diploma and TVET courses.
- Direct comparison of flow readings from the venturi meter, variable area meter and orifice plate.
- Calibrating each meter against the volumetric measuring tank of the bench.
- Measuring head loss across each meter and comparing pressure drops.
- Extending the study to a nozzle meter and plug-in meters such as the Venturi Flowmeter on the Flow Meter Calibration apparatus.
Standard Scope of Supply
Each unit includes the venturi meter, variable area meter and orifice plate in their series circuit, the flow control valve, the eight-tube manometer bank with manifold and air bleed valve, the hand pump and the support framework. The hydraulics bench that supplies and measures the water is ordered separately.

As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. Say how many groups will share the unit on the contact page, line it up with a bench in the enquiry cart, or use the lab tender page for tendered purchases.
Frequently Asked Questions
Which flow meters are included?
Three: a venturi meter, a variable area meter and an orifice plate, installed in series so the same flow passes through each and their readings can be compared directly.
Can it be used without a hydraulics bench?
It is designed to stand on a hydraulics bench, which provides the water supply and the volumetric tank used to calibrate each meter, so a bench is needed for normal use.
Does Science Lab Supplies manufacture it?
Yes. The demonstration unit is manufactured in-house at Saha, Ambala, India, so your enquiry goes to the people who build it rather than to a reseller.
Why is a hand pump fitted?
The hand pump pressurises the manometer manifold so that the water columns sit within the readable range of the tubes during tests, and the air bleed valve on the manifold lets trapped air out before readings are taken.
