Talgil Console Software - Water Sources & Master Valves

In modern irrigation systems, components like water sources, master valves, and irrigation lines play distinct yet interconnected roles. Talgil’s Console Software provides precise tools to configure, monitor, and automate these elements, ensuring efficient and sustainable water management.

This post explores the key differences between water sources and master valves, their roles, and how they interact with irrigation lines within Talgil’s platform.

How Water Sources and Master Valves Interact with Irrigation Lines

In Talgil’s systems, water sources and master valves interact dynamically to ensure efficient water delivery. Here's how they complement each other:

1. Water Source to Irrigation Line:
   - A single water source can supply multiple irrigation lines simultaneously.
   - Pump combinations at the source are adjusted to meet the flow demands of all active lines.
   
   
2. Master Valve in Action:
   - Each irrigation line has a dedicated master valve.
   - The master valve regulates water flow into the line, ensuring that other lines remain unaffected by its operation.
   - Master Valve can be also used as a single pump-start.
   
   
3. Unified Control:
   - Talgil Console Software coordinates water sources and master valves to prevent flow conflicts and optimize pump usage.

Key Differences Between Water Sources and Master Valves

The complementary relationship between these two components ensures flexibility at the source level and precision at the line level.

Water sources in Talgil Console Software are versatile components capable of serving multiple irrigation lines simultaneously. They can include:

• Pumps: Operate individually or in combinations to meet flow demands
• Water Meters: Measure water usage in real-time.
• Sensors: Monitor pressure and operational efficiency.

The Water sources perspective can be reached from the Main menu or the Pull down menu by selecting Plan -> Water sources.

The subject will be included in the Menus only when the image of the controller contains Water sources (WS must be added using the Image Maker).

Important Note

After adding Water Source - Technician MUST activate the WS in the menu.

If not activated - the Console Software will allow you to run the Irrigation Program - but won't start the pump.

Operational Modes of Water Sources:

• Static Mode: Activates a predefined pump combination for consistent flow.
• Nominal Flow Mode: Selects pumps based on the planned flow requirements of active irrigation lines.
• Actual Flow Mode: Dynamically adjusts pump combinations based on real-time data from irrigation lines.

Notes:

Optionally a Delay can be defined that in Static mode it becomes effective when the water source shuts down (first the irrigation is terminated and after the delay the source will shut down) and in the other modes the Delay will be in effect each time that the combination of valves must change due to change in the flow.

Optionally a Flow limit can be set per each water source that defines the maximal flow that can be obtained from that source. If a program needs to be started, but the flow demand of the valve to be opened added to the flow of the valves already running under that Water source, exceeds the limit, it will cause the program to wait.

Defining Water Source in Irrigation Program

To define Water Source in your sequence -

After Adding the desired valve sequence -> Right click on the sequence and select the desired WS

System Example #1

Here is a screenshot of I/O Tab from a system with 4 Irrigation Lines and 4 Water Sources (with multiple pumps)

Where each WS has Water Meter.

System Example #2

Here is a screenshot of I/O Tab from a system with one Irrigation Line - One Water Source with two Pumps working in Nominal Flow Operation Mode.

Pump 1 is activated between flow 0-55m3/h

Pump 2 is added if the flow exceeds 55m3/h to 190m3/h (Both pumps are activated).

Adding Water Meters to Water Sources

To add a water meter to WS - we will use the 'Free Water Meter' feature.

In Talgil Console Software, a Free Water Meter refers to a water meter that is not directly tied to a specific irrigation line or program but is instead used to monitor and measure water flow at a general or system-wide level. These meters are often deployed to track the flow from a water source or a pump that supplies water to multiple lines or uses.

For example - as per the screenshot below:

2 Water Sources (WS A - Irrigation Pump and WS B - Frost Pump)

PRO TIP

You can use Virtual Water Meter - to combine both water meters

A Virtual Water Meter in Talgil Console Software is a software-based tool used to calculate water flow and usage by combining data from multiple physical water meters. Unlike physical meters, which measure water flow at a specific point in the system, virtual water meters aggregate or simulate flow data for broader analysis and management.

Master valves act as gatekeepers, regulating water flow into specific irrigation lines. Unlike water sources, a master valve is tied exclusively to one irrigation line and cannot serve multiple lines. This dedicated functionality ensures:

• Safety: Prevents overflows or leaks by shutting off water flow when the line is not in use.
• Precision: Enables fine-tuned control of water distribution for a single zone or crop area.
• Synchronization: Works seamlessly with sectional valves and irrigation schedules to deliver water exactly where it’s needed.

Master valves also provide an additional layer of protection by isolating individual lines for maintenance or emergency shutdowns.
