Measuring tube for performing magnetically inductive flow measurement of e.g. liquid medium, has flow-parallel grooves provided in side that is turned towards measuring medium, where grooves are formed in trapezoidal form in cross-section

摘要

#CMT# #/CMT# The tube (1) has flow-parallel grooves (3) provided in a side that is turned towards a measuring medium e.g. liquid medium, where the tube is lined with a tubular liner (5) consisting of polymer for guiding the measuring medium. The flow-parallel grooves are formed in trapezoidal form in the cross-section, where the breadth of flow-orthogonal grooves is small in comparison to the breadth of the flow-parallel grooves and/or the depth of the flow-orthogonal grooves is small in comparison to the depth of the flow-parallel grooves. #CMT# : #/CMT# An independent claim is also included for a device for determining and/or monitoring the flow of a measuring medium by a measuring tube. #CMT#USE : #/CMT# Measuring tube for performing magnetically inductive flow measurement of a fluid medium such as liquid, steam or gaseous medium. #CMT#ADVANTAGE : #/CMT# The flow-parallel grooves are provided in the side that is turned towards the measuring medium e.g. liquid medium, so that decrease of a supply and discharge line before and/or after the tube and/or a reduction of accumulations of biological organisms in a piping system can be achieved. The tube can be manufactured in a cost-effective manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a measuring tube formed with flow-parallel grooves. 1 : Measuring tube 3 : Flow-parallel grooves 5 : Tubular liner 6 : Supporting pipe.
