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)3/2 √ g 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.
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.
