Flow ranges of the coriolis mass flow meters with accuracy ±0.1%, ±0.2% and ±0.5% are shown in Table 1.2. Normal operation of the coriolis gas flow meter guaranteed within the full flow range according to the Table 1.2.
Operation of the coriolis mass flow controller with the flow rate exceeding the upper limit of the full flow range will not be within specification.
The lower limit of the full measuring flow range depends on the parameters of the medium, and must be specified in the order. The turndown is typically 10:1. The lower limit is not zero. See Flow Ranges in Tables 1.2.1-1.2.8
