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

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

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
