Measuring system for measuring mass flow, density, temperature and/or flow rate

摘要

The present invention is a main pipe 10 from the feeder 36 to the consumer 40; A first Coriolis meter 12 disposed in the main pipe 10, a second Coriolis meter 12 disposed in the main pipe 10 in series with the first Coriolis meter 12, and designed to have a maximum flow rate smaller than that of the first Coriolis meter 12 a meter 34 comprising a meter 14 , a bypass pipe 16 bypassing the second Coriolis meter 14 , and a valve 18 disposed in the bypass pipe 16 ; and a computer (32) coupled to the first Coriolis meter (12) and the second Coriolis meter (14), the measuring system for measuring mass flow rate, density, temperature and/or flow rate, the valve (18) is opened according to the pressure, and an outlet pressure controller 38 is disposed in the main pipe 10 downstream of the measuring instrument 34 .
