customer's request , the threshold flow rate can be set at any value within the range of Q
The maximum permitted error in fluid volume measurements at flow rates between Q
(excluding) is: 5% irrespective of the fluid temperature.
The maximum permitted error in fluid volume measurements at flow rates between Q
(including) is: 1% for the fluid temperature not exceeding 50°C, and
3% for the fluid temperature greater than 50°C.
