The air tightness measuring tube is used during wartime to detect the air tightness of the interior of a structure (i.e., it must have good sealing performance to ensure that toxic gases and agents outside the civil air defense project do not enter the interior, thus safeguarding the safety of personnel). The pressure measuring tube is used to check the pressure difference between the inside and outside of a room.

The Duwei wind speed and air volume transmitters utilize a differential pressure measurement method, employing an air volume bar or a pitot tube for wind pressure collection. After being measured by the differential pressure transmitter, the data is converted by the Dewey intelligent digital display instrument to directly obtain the wind speed and air volume values. It is easy to use and highly stable.

Solution for Air Safety Guarantee System of Epidemic Prevention and Control for Overseas Input 2020-05-14

The air safety assurance system for preventing and controlling the spread of imported diseases primarily involves deploying safety isolation rooms at airports. The system comprises control software, intelligent differential pressure transmitters, micro-control units, variable air volume (VAV) terminals and air volume sensors, air valve actuators, disinfection purifiers, and other hardware components. Utilizing patented intelligent differential pressure transmitter technology, combined with the micro-control unit and VAV terminals, the system calculates the real-time differential pressure values fed back by the intelligent differential pressure transmitters. The results are then fed back to the compensating fans and air valve actuators, adjusting fan power and air valve opening to bring the real-time differential pressure values within the set range. This enables real-time and precise control of air supply volume, addressing pressure gradient control issues in various functional areas. The ultimate goal is to control air flow direction, prevent the leakage of bacteria and viruses, and achieve the objective of disinfection and prevention of cross-contamination.
