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 total. 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 a pulse input from the flowmeter. 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 sensor, several
options are available.
Standard outputs

Pulse output to transmit a pulse that represents a totalized quantity as programmed.

Negative / positive pulse output indication.

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.
