Flanged type flow tube - Imperial flanged type flow tube is a full flanged type tube constructed of a flanged section, throat sectio 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 desiged as to allow mounting between standard flange ratings. They are designed per specification or beta reatios.

Weld-in type flow tube - Imperial weld-in type flow tube is constructed of a shell bady, 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 beveled ends alloing 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. The entrance section shall be fabricated from specified material with a continuous radius into the throat section. The high and low pressure metering taps shall be made a apart of the hoding flange and shall not require any drilling or tapping of the external pipeline. The holding flange section shall be so designed as to allow mounting between sstandard flanges the recovery cone section shall be fabricated from specified material designed to minimize permanent pressure loss. This flow tube shall have the capabbility of being designed to specification or any beta ratio.
