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.
The curve Q(h) is joined with each Venturi channel.

In our standard models, you may choose between 4 types of instruments, 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.
