Venturi Meters
Venturi Meters are flow measuring devices that operate on the basis of the Bernoulli’s principle. Typically Venturi Meters have 3 Connections
- 1. Inlet
- 2. Outlet
- 3. Pressure measuring taps
The Bernoulli’s principle states that any increase in speed of fluid leads to a decrease in its pressure. Venturi meters are a device which gradually reduces the flow area and measures the pressure difference between pressures at inlet and pressure at reduced area. By measuring the pressure difference it calculates the speed of the fluid in the reduced area and thus the flow.
Venturi-meters are used for precise measurement of both Liquid and Gas fluids for full pipe flows.
Typical Applications
- Gas Flow measurement
- Water Flow measurement
Features of our Venturi Meters

- Available in multiple configurations – Flanged connections, welded end connections, to be inserted inside the pipe.
- Large range in terms of size ranging from DN 50 (2”) to DN 1500 (60”)
- Comfortable with both vacuum and high-pressure flow conditions
- Comfortable with both Cryogenic and High Temperature conditions
- Excellent Repeatability
- Less than 1% Error in flow measurement (in accordance with Global Standards).
- Available in a large variety of materials
| Metallic | Non Metallic |
|---|---|
| Stainless Steels SS 304 / SS 316 | PP (Poly-propylene) |
| Duplex & Super Duplex Stainless Steel | PTFE (Poly-tetra-fluoro-ethylene) |

Benefits of our Venturi Meters
- Low Pressure Loss across the Venturi-Meter
- Static Device without any moving parts – ensure long reliability and maintenance free operation.
- Tolerate entry of liquids & solids particles into the ejector – avoids abrupt breakdowns.
- Small & compact size – allows installation in tight spaces & difficult to access areas.
- Silent Operation
- Non sparking operation – can be safely used in hazardous & flammable areas
- Manufactured in multiple materials – allows using the most cost-effective & chemically compliant materials for the application.
