Net Ratemeter & Net Totalizer
Description
The KEPtrol F/C is designed to measure the net flow of boiler fuel. Separate K-Factors can be entered
for A and B inputs. Two SPDT relay alarm outputs are standard. A scaled pulse output is standard for
interfacing with remote devices. An analog output option is also available to interface with strip chart
recorders.
Features
❑ Flow (A) - Flow (B) Displays Net Rate & Net Total
❑ Pulse Input to 10 kHz Count Frequency
❑ Separate K-Factors for A & B Inputs
❑ Set Point Alarms
❑ NEMA 4X / IP65 Front Panel
Application
The unit is normally used to measure the net flow of boiler fuel. The display may be toggled between net
rate, and net total. Two programmable K-factors make keying-in engineering units easy. The unit accepts
pulse or contact closures and provides two separate preset controls.
