Bamo Debitflo Venturi Open Channel

Overview

Bamo Measures Sas has been founded in 1978. Its capital is now 400 000 Euros. Since the beginning, the company has undergone a rapid development centring on industrial pH-meters and conductivity meters. Bamo is now well-known as a leader on the French market.

Since 1990, new developments in the Level Measure have given a new spring in the export. To its own production range, the company holds numerous agencies of foreign companies in Europe and all over the world. So we are offering a complete line with always the best possible service.

General Information

The open channel DEBITFLO is designed for flow measurements up to 2500 m³/h.
Made of reinforced polyester, DEBITFLO has an excellent dimensional stability, guaranteeing good measurement accuracy.

In association with a level transmitter, it is the right solution for continuous flow measurement, reliable and accurate.

For flows up to 100 m³/h, it is possible to provide the channel inside a polypropylene housing. Over 100 m³/h, the approach channel (1 or 2 parts) may be supplied or not if on site the approach channel is made on concrete structures accordingly to recommendations and standards.

Description:

The Venturi is a restriction (lateral contractions) which ensures a laminar flow at the point of measurement. The upstream level (h) is directly related to the flow (Q). The table Flow vs. level is supplied with each Venturi channel.

Polypropylene housing: Simplified commissioning
On request, we supply assemblies integrated in a polypropylene housing allowing a simple and mobile installation.

Open Channel Venturi Channel Debitflo

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.

Polypropylene housing: Simplified commissioning

On request, we supply assemblies integrated in a polypropylene housing allowing a simple and mobile installation.

Conformity with ISO 4359:

DEBITFLO channels for flow rate from 100 m³/h and greater, comply with standard ISO 4359.
Please note: Models DF7A, AV07A, DF20A, AV25A do not comply with ISO 4359, due to a throat width < 100 mm.

Principle:

Open Channel 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.
Flow rate calculation:

Q = (2/3)^3/2 √ g C_v b_e h_e^3/2

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

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