产品概述
流量喷嘴（Flow Nozzle (ISO 5167 Long Radius)）
流量喷嘴因结构原因成本高于孔板，但适用于高温、高压流动流体的流量测量。
在相同测量条件下，流量喷嘴机械强度高，可通过比相同孔径孔板多 60% 以上的流量，对含固体颗粒流体的流量测量所受扰动也比孔板小。因此也适用于高速流体。
除喷嘴单件外，也可以在上、下游两侧焊接短管的测量管段形式供货。
English description
The Flow nozzles, more costly than other orifice due to their structure, are suited for determining the flow rates of fluids flowing at high temperature and high pressure. Under the same measuring conditions, a flow nozzle has a higher mechanical strength, can permit the flow of more than 60 percent greater volume of a fluid, and can measure the flow rates of fluids containing solid particles less disturbed, than an orifice having the same bore. Thus, they are suited, in addition, for highspeed flowing fluids. We can supply not single flow nozzles, but also flow nozzles having welded short pipes on both their upstream and downstream sides.
