PRINCIPLE

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 aggressi- ve.

Venturi channel is a channel with a width narrowing. Correlation exists bet- ween flow rate value and the height of upstream fluid when the difference of height between upstream and downstream is greater than 0.25 h.
Flow rate calculation:

Q = (2/3)3/2g Cv be he3/2

Q : Flow rate [m3/s]
Cv : (He / he)3/2
b : Venturi width [m]
h : Effluent height [m]

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

DESCRIPTION

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.
