1. product introduction
Differential pressure orifice Flowmeter is widely used in measuring petroleum、chemical、electric power、metallurgy、textile industry etc. This product has the advantages of simple structure、 high accuracy measurement、stable and reliable performance、 easy to operate and maintain. Our manufacturing throttling gear conform to the provision of ISO5167 and GB2624-81. the throttling parts can divided into orifice plate、 nozzle、classical wenturi, at the same time we produced non-standard throttling gear, such as 1/4 round nozzle、double orifice、radius nozzle segmental orifice、eccentric orifice plate. According to user requirements can supply a valve, double chamber equalizer which are isolator, condenser, can also be used to map processing.
