Flow tubes - Manufactured flow tubes combine increased rangeability with lower permanent pressure loss. These tubes are offered in flanged type, weld-in, and insert. Imperial flow tubes are a versatile differential pressure device capable of extreme pressure and or temperature limits, yet maintaining highly accurate readings with the lowest permanent pressure loss.

Accuracy - The completeness of published research data permits Imperial to provide the ASME type tube with an accuracy of 0.5 percent without the need of flow calibration. Flow calibration is available to provide nozzles with 0.25 percent accuracy when necessary.

Flanged type flow tube manufacturers - Imperial flanged type flow tube is a full flanged type tube constructed of a flanged section, throat section with a flanged recovery cone. Tne entrance section is fabricated from specified material with a continuous radius into the throat section. The high pressure taps are located within this section. The flanges shall be designed as to allow mounting between standard flange ratings. They are designed per specification or beta ratios.

Weld-in type flow tube - Imperial weld-in type flow tube is constructed of a shell body, throat section with a weld-in recovery cone. The entrance section is fabricated from specified material with a continuous radius into the throat section. The high pressure taps shall be located within this section. This flow tube is fabricated as bevelled ends allowing it to be ready for welding into the pipe line.

Insert type flow tube - Imperial Insert type flow tube is constructed of an entrance section throat and holding flange section with a recovery cone.
