The threshold flow rate (Q
NEC
) is the minimum flow rate at which the meter starts to indicate and process the fluid
flow parameters. At the manufacturer’s plant, Q
NEC
is set at a value corresponding to the flow velocity of 20mm/s. On
customer’s request , the threshold flow rate can be set at any value within the range of Q
NEC
= 0.1

.
The maximum permitted error in fluid volume measurements at flow rates between Q
1
(including) and Q
2
(excluding) is: 5% irrespective of the fluid temperature.
The maximum permitted error in fluid volume measurements at flow rates between Q
2
(including) and Q
4
(including) is: 1% for the fluid temperature not exceeding 50°C, and
3% for the fluid temperature greater than 50°C.
