Description
Interval Time for Flow Rate Calculation.
FlowInterval (>= 0) is the interval time, in seconds, after
which the the flow rate of TOV must be calculated
again.
Flow Interval is checked each time that the tank is cal-
culated ([ProductLevel] is measured).
Not
Flow Rate Multiplication Factor.
Damping Factor for Flow Rate Calculation.
To obtain a steady flow rate, a damping factor (0.0 <
FlowMul <= 1.0) is used.
If FlowMul = 1.0, the flow rate is not damped at all, but it
can be very unstable then.
If the flow

Flow Rate Calculation Trip Value.
Whenever FlowTOV is calculated, the actual calculated
TOV is compared with TOV at the time of the previous
check, see FlowInterval.
If the difference exceeds the value of FlowTrip, thus
reducing the effect of external in

This compensates the volume for the effects of dynamic
loads like snow, rain water on top of the floating roof.
