Commercial & Bulk Purchasing
We support operations & licensed facilities with volume pricing, dedicated account managers, and custom equipment consultation.
Who This Is For
- You are switching to volume-based feeding because your timer-based cycles fail to deliver consistent doses when line pressure shifts
- You are adding high-capacity flow monitoring because your irrigation system currently lacks the precision to verify if your crop received its target volume
What We Found
- We tell growers the move to volume-based control is the fastest way to stabilize their irrigation programme across large lines
- The DFM-2 builds on the proven reliability of the original unit but handles the heavier flow rates required for larger pipe diameters
What Users Say
- Operations that switched to volume-based feeding say they stopped seeing inconsistent nutrient uptake across different irrigation zones
- Managers who integrated the flow meter into their daily routine report they have stopped worrying about over-watering during pressure fluctuations
TrolMaster DFM-2 1.25" Digital Inline Flow Meter
Managing large-scale greenhouse irrigation requires precision that standard timers simply cannot provide, especially when dealing with 1.25" main lines. The TrolMaster DFM-2 is the high-capacity solution for commercial growers, offering the same meticulous volume-based control as the TrolMaster DFM-1 but scaled for larger pipework. By integrating seamlessly with your TrolMaster Aqua-X Pro system, this digital flow meter eliminates the guesswork of pressure-dependent timing.
This advanced sensor doesn't just measure; it communicates. It monitors nutrient solution flow in real-time, signaling your controller to halt irrigation the moment your plants have received their exact target dose. Beyond current functionality, the DFM-2 features a future-ready architecture designed to support upcoming firmware updates for leak detection and line blockage sensing, ensuring your facility remains at the cutting edge of water management.
Compatibility: TrolMaster Aqua-X Pro System (GCS-1)
What's Included
Features
Volume-Based Irrigation
Allows the Aqua-X Pro to feed by precise volume rather than time for consistent dosing.

FAQs
The primary difference is pipe size. The DFM-1 is designed for 1" irrigation lines, while the DFM-2 fits 1.25" lines. Both meters share the same functionality — real-time flow measurement, onsite LCD display, and volume-based irrigation control within the Aqua-X Pro system.
Time-based irrigation assumes consistent pressure. Volume-based scheduling with the DFM-2 removes that assumption, delivering the exact quantity of nutrient solution intended regardless of pressure fluctuations, pump wear, or line resistance changes.
When connected to the Aqua-X Pro controller, you set a target volume per event. The DFM-2 measures actual flow in real time and signals the controller to close the valve once the desired volume has passed through the line.
The DFM-2 is designed specifically for the Aqua-X Pro irrigation control system. Always confirm compatibility with your specific GCS-1 configuration via TrolMaster documentation before purchasing.
The hardware is built to support leak detection and line blockage sensing, which TrolMaster plans to enable via future firmware updates. This capability is not active in the current firmware release.
The GCS-1 typically supports one digital flow meter per controller set. For operations with multiple independent irrigation mains, each line would require its own dedicated controller and flow meter.
