Chapter 2 - TeleFlow Standard ACCOL Load
TeleFlow™ 2-9 Standard ACCOL Load
Low-Flow Cut-OFF
The 'live' Differential pressure is always compared to a CUTOFF signal set in
inches of water. When the DP value drops below the value of the CUTOFF signal,
flow calculation will cease and the calculated flow-rate will be zero. Default cutoff is
0.25 inches of H
2
O.
Flow Time
While the DP is above the Cutoff limit the unit will accumulate a flow-time count
in minutes for the hour and day. In a backflow condition a separate backflow time
is accumulated.
