Distributors
► Function
This equipment can be installed in canals or reservoir outlets. They can supply a practically constant flow rate, independent of upstream level fluctuations (within certain limits indicated in the corresponding diagrams).
- They guarantee a constant flow rate for free water discharge.
- ON/OFF opening.
- Manual operation (can be automated on demand).
► Application
- Measurement of irrigation deliveries for equitable flow distribution.
- Measurement of inflow to reservoirs
- Measurement of ouflow to reservoirs
► Features and Tips for use
Inspired by a simple hydraulic conception, they are totally robust and devoid of any mechanical complication, which allows them to adapt to the most severe working conditions. They can be automated.
Features
- Precise and robust equipment.
- Service transparency (ON/OFF opening).
- Manual and simple operation.
- Low and simple maintenance.
- Easily monitored for instantaneous flow data (with installation of limit switches for OPEN or CLOSED register).
- Easily remote controllable (with installation of electric actuators).
Tips about use
- Upstream level variation must be compatible with the variation allowed by the equipment.
- Downstream level must be compatible with the head loss of the equipment.
- May leak minimally.
- It is suggested that protective fencing be installed to minimize possible vandalism to the gates.

Remote Controlled Radial Gate
► Function
This equipment can be installed in canals. They allow an optimal distribution of the available water, by precise operations automatically operated with upstream and downstream level data. This gate design optimizes the hydraulic head forces on the equipment, allowing a significant reduction of the energy required for its operation (allows the use of solar energy).
- They guarantee optimal measurement and distribution of the resource.
- They can be remotely controlled and integrated into the management systems of the irrigation communities.
► Application
- Measurement of irrigation deliveries for equitable flow distribution.
- Measurement of inflow to reservoirs
- Measurement of ouflow to reservoirs
► Features and Tips for use
Inspired by a simple hydraulic conception, they are totally robust and devoid of any mechanical complication, which allows them to adapt to the most severe working conditions.
Features
- Precise and robust equipment.
- High accuracy of the delivered flow rate.
- Minimal electrical energy necessary for operation.
- Allows regulation of upstream level, downstream level, through flow, other parameters.
- Modular installation based on the formwork canal section component.
- High sealing performance.
- Simple and economical maintenance.
Tips about use
- Allows to share with several equipments, the installation of level sensors and PLC, economizing the solution.
- It is suggested that protective fencing be installed to minimize possible vandalism to the gates.

Parshall flume
► Function
This equipment is installed in canals or small rivers. Designed by the engineer Ralph Parshall, they are characterized by incorporating a small jump in its sill, a situation that promotes the creation of a critical hydraulic regime, ideal for the measurement. They are manufactured according to ISO-9826 designs.
- They allow to measure flow rates with high accuracy.
► Application
- Irrigation canals.
- Small rivers.
► Features and Tips for use
Inspired by a simple hydraulic design, they are robust and can be adapted to the most severe working conditions.
Features
- Wide range of dimensions for a high range of flow rates.
- Standard dimensions.
- Simple to install.
- Low maintenance (only painting).
- Second measurement option for submergence correction up to 90%.
Tips about use
- Maximum submergence is 50% for models PA030, 60% for models PA110 and PA250, 70% for models PA455 to PA3K9 and 80% for models PA8K3, PA15K and PA25K.
- A minimum homogeneous flow distance upstream of the equipment must be respected ( contact our specialists).
- They are manufactured by default in carbon steel with surface treatment, but can be manufactured in stainless steel or other steel under customer's request.
