The air volume cover is mainly composed of three parts: an air volume cover, a base, and a PDA. The air volume cover is mainly used to collect the air volume, and the wind is collected on the basis of the wind speed uniformity device.
How the hood works:
A wind pressure sensor is installed on the wind evenly, and the sensor responds to changes in the wind speed, and the air volume is calculated based on the size of the base. The display of the air volume cover adopts the PDA. The large-screen LCD display is intuitive, and the data of the wind speed and air volume can be directly obtained. The continuous recording of the parameters can be set at the recording time interval to analyze the data. The measured and recorded data is recorded on the memory card and will not be lost. The data can be transmitted to the PC via the serial port of the computer and further applications can be made.
The use of air volume cover:
The air flow at the tuyere in the centralized air conditioning system is more complicated and the measurement work is more difficult. Only when it is not possible to measure at the branch pipe, it is measured at the tuyere. Generally, the tuyere and tuyere are used.
Compared to the tuyere speed method, the air volume hood can quickly and accurately measure the average ventilation volume of the tuyères. Whether it is a delivery, return or exhaust outlet installed on the ceiling, wall or ground, the corresponding sensors can directly read out the wind speed, pressure and Relative humidity and temperature, especially for diffuser tuyere. When used, the cover is tightly attached to the ceiling, so that the tuyere can be completely contained and can be read directly.
