For example, if the average flow rate is 100 gpm and the

Hysteresis

is set to 10%, a filter window of 90…110 gpm is

established Successive flow measurements that reside within that window are recorded and averaged in accordance with the

Damping

setting Flow readings outside of the window are rejected or accepted in accordance with the

Bad Data Rejection

setting

Figure 27: Hysteresis window

Bad Data Rejection (Range 0…10 Samples; Default: 3)

The

Bad Data Rejection

setting is related to the number of successive

readings

that must be measured outside of a the

Hysteresis

value before the flow meter considers the new flow value valid In this example, a

Hysteresis

setting of 10% produces

a ± 10% band centered on the current valid flow rate of 100 gpm
The

Bad Data Rejection

setting is the number of successive

samples

that must be outside of the

Hysteresis

window before

the flow meter considers the change in flow as real Larger values are entered into the

Bad Data Rejection

window when

measuring liquids that contain gas bubbles, as the gas bubbles tend to disturb the ultrasonic signals and cause more

extraneous flow readings to occur Larger

Bad Data Rejection

values tend to make the flow meter less responsive to rapid

changes in actual flow rate
In

Figure 29 on page 23

flow data falls outside the flow

Hysteresis

window but does not reach the minimum time specified in

the

Bad Data Rejection

window When data appears that is outside the

Hysteresis

band and shorter than the

Bad Data Rejection

window time, the data is rejected
