● Thermal mass differential pressure principle：
High accuracy ±1.5% F.S., without the need for temperature or pressure compensation
● Turndown ratio 100:1 with high sensitivity design：
Superior to conventional differential pressure sensors in detecting subtle airflow variations
● On-site K-factor correction：
Simple calculation allows input of the corresponding K-factor to align measurements with true values
● Real-time display & system integration：
Capable of showing flow velocity/flow rate, and with eyc-tech DPM03 / DPM04 enables full-range linearization and totalizing flow calculation
● Versatile outputs：
Supports Analog / Relay / RS-485, making system integration flexible and convenient
● Easy installation：
Ferrule fittings for flexible or rigid tubing.
● High compatibility：
Applicable to a wide range of differential pressure elements (Pitot tube, averaging tube, Annubar, Venturi, orifice plate, V-cone, etc.)
