网友解答：1、绝压压力表的压力测量与大气压的波动无关，适合测量气体和液体。

There is no connection between the pressure measurement of the absolute pressure gauge and the fluctuation of the atmospheric pressure . Therefore , the gauge is suitable for measuring gas and liquid .

某些类型的压力传感器，特别是绝压传感器，已经不能像以前一样使用统一的方法来校准，校准工作变得复杂多样。

Certain types of pressure sensors , in particular , absolute pressure sensor , is no longer the same as before , using the unified approach to calibration is not suitable , and the calibration is becoming complicated and diverse .

首先通过传感器采集流量积算所需的差压、绝压和温度信号，再通过A/D转换器将模拟量转变为数字量，由微控制器进行处理、积算。

The system firstly collects the differential pressure , absolute pressure and temperature signals through sensors flow accumulation . Then , the analog signals are converted into digital signals through A / D conversion , which are sent to the microcontroller to be disposed and calculated .
