Note: it is important the differential reading drop slowly.
注意：重要的是压差读数慢慢下降。
After initial pressure differential reading is taken, refer to flow rate charts to obtain flow rate based on pressure differential and valve setting.
在获得初始压差读数后，参阅根据压差和阀门设置而得的流量表。
If the differential reading does not decrease record check as tight.
如果压差读数没有降低，则记录止回阀为密封紧密。
Record this as the opening differential pressure of the relief valve.
将此读数记录为安全阀开启压差。
"The reading on the gauge, called the gauge pressure, is always the difference Between two pressures."
标尺上的读数,称为计示压力,通常是两个压力数之差。
Usually the rake body makes the static readings high, and by shortening the tipstatic-orifice distance the error can be eliminated.
一般排管架使静压读数偏高，缩小管端静压孔的距离可以消除这个误差。
At this point the gauge pressure was read.
