⚙️ Operating Principle

Low flow transmitters measure minimal pressure or flow changes in small pipelines:

Process fluid applies pressure to the diaphragm.
The DPharp sensor detects diaphragm deflection at very low ranges.
The signal is processed by the electronics.
The output signal is transmitted to the control system.

This ensures precise dosing, energy efficiency, and process safety in low flow applications.
