Signet 8150 Flow Totalizer

Sensitivity

The SENSITIVITY setting determines how the 8150 responds to sudden surges in the flow rate. It "overrides" the SPEED function just 

long enough  to allow an actual change in flow rate to be displayed, then resumes the averaging. The result is a smooth flow display 

and a quick response to large shifts in the flow rate.

No AVERAGING, no SENSITIVITY

With SPEED averaging set to 0 (zero) and with SENSITIVITY set 

to zero, the flow rate may be very unstable.  This line represents 

the actual output of the flow sensor as it responds to unstable 

flow conditions in the pipe.

With SPEED set to 60 seconds and SENSITIVITY still set to zero 

the flow rate is stabilized, but a sharp change in flow rate is not 

represented for 60 seconds or longer. (dotted green line).

With SPEED at 60 seconds and SENSITIVITY set to 6, the flow 

rate is stabilized, while the sudden shift in flow is reflected very 

quickly (dotted blue line).

NOTE:

 The SENSITIVITY function is ineffective if the SPEED function is set to zero (seconds).

The display shows DISP SENS and the current  

sensitivity setting.

3.  Press the ► key to select the SENSITIVITY for editing. 

The current SENSITIVITY setting begins flashing.

4.  Press the ▲ key three times to scroll from 5 to 8.

5.  Press the ENTER key to return to the menu.
