HQD High-pressure active piston proves uncertainty is better than 0.05%, flow range covers from 0.1 ml/min to 1000 L/min, up to 600 kPa (absolute pressure) working pressure for different types of wet gas flow meters, sonic nozzle, thermal flow meters, mass flow meters, laminar flow meters, orifice meters, float flow meters, soap film flow meters, diaphragm gas meters and ultrasonic gas meters for research and development, experimentation, verification, type evaluation, quantity, value transmission and tracing of gas flow meter.

The HQD high-pressure active piston proves unit features a stable flow rate to ensure consistent measurement results under varying operating conditions. In addition, the user can flexibly adjust the working pressure according to the actual needs to adapt to different experimental or production environments. This design not only improves the adaptability of the device, but also provides greater flexibility for the user.

With its fast measurement speed and efficient automatic control system, the HQD proves significantly improves work efficiency. Users can quickly obtain accurate flow data, to make timely calibration and development adjustments to ensure a smooth.

The HQD high-pressure active piston proves to be the ideal solution for gas flow measurement due to its high accuracy, wide application range, excellent stability and automated control capabilities. Whether you are a researcher, calibration mechanism or tester, HQD will provide you with a trusted gas flow measurement standard to help you in the fierce market competition.

By the way, HQD high-pressure active piston proves already has been applied in NIMTT, Hebei Metrology Institute, CEI, Feejoy, CGNPC, YIDU Intelligent, Chengdu Metrology Institute, Shanghai Gas Equipment Testing Center and Chongqing Science and Technology Testing Center.
