Eastern Instruments offers a fully integrated air flow measurement solution: pair the QVT Multivariable Transmitter with a VAP® Pitot tube, DSV Flow Element, or High Beta® Flow Conditioner for mass?airflow readings under real-world conditions, measuring differential pressure, temperature, and static pressure in one smart device. Ideal for dusty or turbulent ducts in industrial environments—such as power generation, process piping, or HVAC—this mass flow solution offers high accuracy, simple calibration, and robust performance. The QVT’s sealed sensor avoids condensate errors common in diaphragm seal setups, ensuring reliability in variable conditions.
