Manufactured Venturi channels are dedicated for flow rate measurement in open flumes, and totalization on effluents. They are useful either on waste water, contaminated fluid even with solids/ particles or chemically aggressive.
Venturi channel is a channel with a width narrowing. Correlation exists between flow rate value and the height of upstream fluid when the difference of height between upstream and downstream is greater than 0.25 h.

In our standard models, you may choose between 4 types of instruments, all with an ISO 4359 Venturi, with or without approach and tranquilization flumes.
They are manufactured in reinforced polyester fibreglass for flow rates from 2 to 2500 m³/h.
For the smallest flow ranges, we can provide a PE module allowing an easiest installation on site. For the greater flow rates we can provide just the Venturi channel, without approach and tranquilization flumes.
