This mass flow/density sensor (10), which can be installed in a pipe and through which a fluid to be measured flows during operation, is to be balanced over a wide density range, so that accurate measurements are possible. A single straight measuring tube (13) having a longitudinal axis (131) extend ...

Ole Koudal, Alfred Wenger: Coriolis-type mass flow sensor with a helical measuring tube. Endress Hauser Flowtec, Barnes & Thornburg, September 24, 1996: US05557973 (7 worldwide citation)

A mass flow sensor is provided to be installed in a conduit through which a fluid flows. The mass flow sensor includes flanges for mounting to the conduit, a single measuring tube, an external support tube, and an internal support element. The measuring tube is fixed at its ends to the flanges and i ...

This sensor (10) generates accurate measuring results, for example with an error in the order of 0.5% of the measuring value, hat has mimimized production costs as well as a shorter overall length compared to that of conventional sensors. The sensor has two parallel V shaped measuring tubes (1, 2) e ...
