integral orifice plate flowmeter (throttling device)1.Simple structure
2.Convenient installation
3.BQC
4.CE approved
integral orifice plate flowmeter (throttling device) is a conical body which is pending in the center of pipeline,it can improve the flow field.the high pressure P1 from tube wall which is the flow body has not yet throttling accelerated before vertebral devices;Low pressure P2 are taken from the after centrum rear,and it can draw forth transmitter branch pipe in front of inner vertebral,its square root of differential pressure(P1-P2) is proportional to the rate of flow,then work out a fluid flow,the products are widely used in flow measurement for the liquid,gas or steam of the steel industry,electric power,chemical etc industry.
Main characteristic
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;
Structure strong,performance stable;
Can be measured the containing impurities of fluid;
Need the before and after straight pipe sections are shorter(before 2D,after 0.5D)
Use the jacket type heat structure,and suitable for the need warming or cooling of fluid.
Technical Parameters
Taking pressure mode:before and after side surface taking pressure,span taking-pressure;
Nominal pressure:≤32MPa(≥20MPa,it can use welding type);
Caliber:50~2200mm;
Accuracy(indeterminacy):+/-2.5% actual demarcate can be reach+/-1%;
Range of application:open hole diameter rate β:0.5 ≤ β ≤ 0.72
