Coriolis mass flow measuring device

摘要

The device (1) has a sensor arrangement (2) comprising a measuring tube (4), oscillator (5) and a vibration detector (6), where the measuring tube is excited by the oscillator in an operating frequency. A reinforcement element (10) is arranged within a housing (3) and connected with the housing such that realized resonance frequency of the housing is displaced away from the operating frequency of the measuring tube. The measuring tube is curved in a U-or V-shape. The reinforcement element is designed as a welded hollow frame construction unit. An independent claim is also included for a method for operating a coriolis-mass flow rate measuring device.
