Repeatability = 0.1% o.r. with a measured volume [m
3
]
The repeatability can be improved if the measured volume is increased. Repeatability is not a device
characteristic but a statistical variable that is dependent on the boundary conditions indicated.
Response time
If all the configurable functions for filter times (flow damping, display damping, current output
time constant, frequency output time constant, status output time constant) are set to 0, in the
event of vortex frequencies of 10 Hz and higher a response time of max(T
ν
,100 ms) can be expected.
In the event of measuring frequencies < 10 Hz, the response time is > 100 ms and can be up to 10 s.
T
ν
is the average vortex period duration of the flowing fluid.
