Nuclear magnetic resonance flow measurement device and method for operating nuclear magnetic resonance flow measurement devices

摘要

The flow meter (1) has a nuclear magnetic measuring device (2) arranged around a measuring pipe (3), and an additional measuring device operating according to measuring principle i.e. nuclear magnetic measuring principle. The additional measuring device is designed as a differential pressure flow measuring device (5) for measuring differential pressure of multi-phase medium in the measuring pipe. Pressure gauges (8a, 8b) i.e. pressure sensors, are arranged at respective longitudinal points (6a, 6b) that are arranged in a longitudinal direction (7) of the measuring pipe. An independent claim is also included for a method for operating a nuclear magnetic volumetric flow meter.
