VOLUME PRICING
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 timer-based cycles vary when pump pressure fluctuates.
- You are adding inline monitoring because you need to confirm nutrient doses without walking back to the controller.
What We Found
- The onsite LCD is a huge help when you are bleeding lines or checking for air pockets right at the pipe.
- We always double-check orders for the SPH-1 power hub because this meter is a paperweight without it.
What Users Say
- Users who switched to volume dosing report much more uniform plant growth across all zones in their facility.
- Operators tell us the live flow data helped them spot a failing pump before any harvest material was lost.
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.

FAQs
What does "feed by volume" mean and why does it matter?
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.
Does the DFM-1 require any additional hardware to operate?
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.
Which controller systems is the DFM-1 compatible with?
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.
What pipe size does the DFM-1 fit?
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.
Can the DFM-1 detect leaks or blockages?
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.
