How Venturi flowmeter works

2024 11/26

The working principle of a Venturi flowmeter is based on the flow continuity equation and Bernoulli's equation. When the fluid flows through the throttling member of the Venturi flowmeter, the flow band forms a local contraction at the throat of the Venturi tube, causing the flow rate to increase and the static pressure to decrease, thus generating a differential pressure before and after throttling. The greater the fluid flow, the greater the differential pressure generated, so the fluid flow can be measured by measuring the differential pressure.

 

Venturi flowmeters have significant advantages in natural gas metering. Compared with the orifice flowmeter, the venturi flowmeter has the same measurement principle, which measures the flow rate by measuring the differential pressure generated when the fluid flows through the throttling device. The modification of Venturi flowmeter is relatively convenient and low-cost, which is particularly suitable for my country's current natural gas measurement needs.

 

Venturi flow meters have a wide range of applications. They are not only used for natural gas measurement, but can also be used in other situations where fluid flow needs to be measured. Its design is based on the Venturi effect, that is, when the airflow passes through the constriction channel, the flow rate increases and the static pressure decreases, thereby forming a vacuum zone at the outlet, which can be used to produce adsorption or for airflow control in industrial equipment.
