注/Note:    150    
1、后背板只适合平面安装(如仪表板、机器外表平面等);2、注意平面要坚固，使差压表安装后牢固，不会
发生掉落;3、特殊后背板可按客户要求出图加工或照来样加工。    1. back mounting fit for plate mounting    
(instrument plate, and outer surface etc) ;2. Make sure the plane and differential gauge are tight, which will not mount the fall off; 3.Special back plate available as per request.(二)固定支架安装Steady rest mounting

注/Note:
1、固定支架安装只适用于管道安装(横向或竖向);2、注意管道的外径不能大于60mm;3、仪表可以装到支架上方或下方，方便用户自由选择。1.Steady rest mounting is suitable for pipe (horizontal or vertical);
2.Outer diameter of pipe cannot over 60mm.

1.正常使用差压表必须配三阀组或五阀组以保护差压表正常工作。
2.差压表和三阀组用两个索母紧固。索母和差压表接头密封面应加四氟垫片。
3.装有三阀组的差压表在使用前必须把中间阀门打开，并把正压阀门和负压阀门打开。当P+和P-任意的压力先进入时，中间阀门能起到平衡差压表两腔体内的压力的作用，以免打坏差压表。
4、当P+、P-的压力正常进入三阀组后，再关闭中间阀门使差压表正常工作。如差压表表针有轻微离零属正常只需把表针调到零位即可。注意必须用肥皂水检验所有密封口是否泄露，如有泄露必须紧固。
5.差压表有后背板式安装(如图)和立管固定方法。(管卡子卡到管子上)
1. Use differential gauge must fit out three valves in order to insure its normal working.
2.The differential gauge and there valves are connected by two nuts tightly, nuts and socket are withPTFEspacer.
3.Open the middle valve, negative pressure valve and positive pressure valve before use the differential gauge, when either of P- or P+ input, the middle valve can have equilibrium activity, and avoid to damage the gauge.
4.When P- and P+ normal input the three valves, then close the middle valve, to make the gauge works right. If the gauge's pointer is not at zero, please adjust it to zero (note must use soap water to inspect the seal, if has leak, please tight.)
5. The differential pressure gauge has back plate mounting (see the chart) and standpipe fixed (the pipe with clamp).
