Features:
1. Instructure: Integral type, annular, standard, restrictive
2. Medium temperature: -20~300Deg C
3. Take pressure method: Corner joint
4. Accuracy: +-1%

Main charateristic:
Annular orifice plate not only can measured the generally fluid flow rate. But also can be used for the measured contains all the impurities of fluid (such as dust, suspension, the precipitation etc), such as all kinds of gas, hot wind, flue-gas, natural gas, cooling recirculating water

1. Structure strong, performance stable.
2. Can measured the containing impurities of fluid
3. Use the jacket type heat structure, and suitable for the need warming or cooling of fluid

Technical parameters:
1. Taking pressure mode: Before and after side surface taking pressure. Span taking-pressure
2. Accuracy(indeterminacy): ± 2.5% actual demarcate can be reach ± 1%
