摘要
在相同的流动条件和相同的流动干扰下,对孔板和V锥所输出的差压信号进行了实测。测试结果表明:与孔板相比较,V锥的信号噪声明显减小。而V锥发生低噪声信号的能力是它能在低差压下正常进行测量的关键和基础。
Differential pressure signals from orifice plate and V-cone were tested experimentally downstream of a same flow disturbance and under the same flow condition. The test results show that the V-cone has significantly less signal noise when compared to a orifice plate. The ability of V-cone to generate this low noise signal is the key in being able to operate at low differential pressure.
