1 INTRODUCTION
1.1 SYSTEM DESCRIPTION
Functions and features
The flow rate / totalizer model F115-P is a microprocessor driven instrument designed to show the
flow rate, the total and the accumulated totals of two flowmeter inputs. This model is able to detect
the flow direction and to show a positive or negative flow rate, the totals for both directions and the
cumulative totals.
This product has been designed with a focus on:
▪ ultra-low power consumption to allow long-life battery powered applications (type PB/PC)
▪ intrinsic safety for use in hazardous applications (type XI)
▪ several mounting possibilities with aluminum or GRP enclosures for harsh industrial
surroundings
▪ ability to process all types of flowmeter signals
▪ transmitting possibilities with analog / pulse and communication outputs.
Flowmeter input
This manual describes the unit with two flowmeter pulse inputs. Other versions are available to
process (0)4-20mA signals.
Two flowmeters with a passive or active pulse, Namur or sine wave (coil) signal output, with a phase
difference of 90 or 270 degrees, can be connected to the F115-P. To power the sensors, several
options are available.
Standard outputs
▪ Pulse output to transmit a pulse that represents a totalized quantity as programmed.
▪ Pulse output indication positive or negative flow.
▪ Linear (0)4-20mA or 0-10V analog output to represent the actual flow rate as programmed. The
(0)4-20mA or 0-10V signal limits can be tuned.
