Who This Is For
- You are moving to volume-based irrigation because traditional timers keep delivering inconsistent nutrient doses when line pressure shifts
- You are integrating precision flow data into your Aqua-X Pro setup because you need to ensure every zone receives an identical volume of solution
What We Found
- The LCD screen at the install point saves us from constantly walking back to the main controller just to verify flow rates
- We tell people to double-check their SPH-1 power hub inventory because this unit will not draw power from the controller itself
What Users Say
- Users report that switching to volume-based dosing ended the guesswork they faced with pump performance fluctuations
- Growers who automated their irrigation volume say they stopped seeing uneven feeding results across different zones
TrolMaster DFM-1 1" Digital Inline Flow Meter
Traditional irrigation scheduling relies on timers, but time-based systems are often inaccurate due to fluctuations in line pressure and pump performance. The TrolMaster DFM-1 1" Digital Inline Flow Meter eliminates this guesswork by enabling true volume-based irrigation. By integrating with your TrolMaster Green-X GCS-1 or Aqua-X Pro system, it measures real-time flow to ensure every zone receives the exact nutrient dose intended, regardless of system pressure variations.
Beyond precision dosing, the DFM-1 features an onboard LCD display for immediate onsite flow readings, allowing you to monitor performance without checking the main controller. Its future-ready architecture is designed to support upcoming firmware updates for leak detection and line blockage sensing. For larger irrigation setups, consider the TrolMaster DFM-2 for expanded capacity.
Compatibility: TrolMaster Aqua-X Pro System (GCS-1)
⚠️ The DFM-1 cannot be powered independently. It requires the SPH-1 power hub to operate — ensure the SPH-1 is included in your system build before ordering.
What's Included
Features
Volume-Based Irrigation Control
Enables the Aqua-X Pro to irrigate by precise volume rather than time, ensuring each zone receives the exact nutrient solution dose.
Real-Time Flow Measurement
Continuously measures water and nutrient solution flow through the irrigation line, feeding accurate data directly to the controller.
Onsite LCD Display
Built-in LCD shows live flow readings at the installation point for quick monitoring without visiting the main controller display.
Future-Ready Architecture
Designed to support leak detection and line blockage sensing via future firmware updates for enhanced system safety.

Support & Manuals
Warranty
TrolMaster backs the DFM-1 with a 3-year warranty from the original date of purchase, covering all mechanical and electronic components under normal operating conditions. Components that fail due to abnormal or improper usage are excluded from this coverage.
FAQs
Feed by volume means the irrigation system delivers a specific quantity of nutrient solution per event, stopping when the target volume is reached rather than when a timer expires. This accounts for variables like fluctuating line pressure and inconsistent pump output.
Yes. The DFM-1 cannot be powered independently and requires the SPH-1 power hub to function. Ensure the SPH-1 is included in your system configuration.
The DFM-1 is designed specifically for the Aqua-X Pro irrigation control system (GCS-1). It is not compatible with the standard Aqua-X or other TrolMaster platforms.
This model is a 1-inch inline flow meter. If your irrigation feed line is a different size, you will need appropriate reducer fittings for installation.
While the current hardware supports these functions, they are intended to be enabled via future firmware updates. Currently, the device focuses on real-time flow measurement and volume-based dosing.
