Orifice and Venturi meter demonstrator Manufacturer,Supplier and Exporter in India

Orifice and Venturi meter demonstrator (Product Code: SLE/MCE/38) is a flow measurement teaching unit used to compare a Venturi meter, a variable area meter and an orifice plate in hydraulics laboratories. The three meters sit in series on one circuit, read against an 8-tube manometer of 0 to 500 mm water column, and the unit stands on a hydraulics bench for its water supply. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Orifice and Venturi Meter Demonstrator Used For?

Differential-pressure flow meters are everywhere in water supply and process plants, and this demonstrator lets students see how three common types behave when exactly the same flow passes through each. They set a flow with the control valve, read the manometer levels at the tappings, and then collect a timed volume in the bench tank to find the true flow rate for comparison.

From those readings a class can work out the coefficient of discharge of the Venturi and the orifice plate, check the variable area meter scale, and compare the permanent head loss each meter causes — the Venturi recovers most of its pressure drop, while the orifice plate does not. Repeating the test at several valve settings across the 2 to 30 l/min range builds calibration curves, a staple exercise for engineering educational equipment in India's polytechnics and colleges.

What to Specify When Ordering

• Whether your laboratory already has a hydraulics bench to supply water and measure volume, since the demonstrator stands on one.
• Confirmation of the orifice plate dimensions required for your syllabus.
• Number of units, based on how many student groups run the experiment at once.

OEM Manufacturer

This Orifice and Venturi meter demonstrator is manufactured by Jain Scientific Equipments Private Limited, the company behind the ScienceLab brand. As the OEM (original equipment manufacturer), ScienceLab builds and assembles the meter circuit, manometer board and framework at its own licensed factory at Saha, Ambala, Haryana, India.

Buying from the maker means one point of contact for quotations, repeat units for additional lab benches and replacement manometer tubes or fittings — ask us about the parts you need. Colleges, training institutes, dealers and importers are supplied factory-direct; the ScienceLab company profile has more about the company.

Frequently Asked Questions

Which flow meters does the Orifice and Venturi meter demonstrator compare?
The Orifice and Venturi meter demonstrator compares a Venturi meter, a variable area meter and an orifice plate installed in series. Because the same flow passes through all three, students can compare their readings and head losses directly at each valve setting.

Does the demonstrator need a hydraulics bench?
Yes. The Orifice and Venturi meter demonstrator stands on the working top of a hydraulics bench, which supplies the water and provides the volumetric tank used to calibrate each meter. If your laboratory has no bench, mention this in your enquiry.

What is the manometer range?
The Orifice and Venturi meter demonstrator uses an 8-tube manometer with a range of 0 to 500 mm water column. A hand pump pressurises the manometer so that the water levels can be brought within the readable part of the scale.

What are the Venturi meter dimensions?
The Venturi meter on the Orifice and Venturi meter demonstrator has a 32 mm upstream pipe diameter and a 20 mm throat diameter, with taper angles of 21° and 14° listed for its converging and diverging sections.

What flow range can be measured?
The variable area meter on the Orifice and Venturi meter demonstrator reads from 2 to 30 l/min. The flow control valve lets students set several flow rates within this range to build calibration curves for the Venturi meter and the orifice plate.

Who manufactures the Orifice and Venturi meter demonstrator?
The Orifice and Venturi meter demonstrator is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory in Ambala, Haryana, India, and quotations come straight from the manufacturer.

Is a calibration certificate supplied?
Calibration certificate availability for the Orifice and Venturi meter demonstrator should be discussed with us before ordering. Please state the requirement through the contact page so it is covered in your quotation.
