1. INTRODUCTION
1.1. SYSTEM DESCRIPTION OF THE F115-P
Functions and features
The flowrate / totalizer model F115-P is a microprocessor driven instrument designed to display
flowrate, total and accumulated total. This model is able to detect the flow direction and display a
positive or negative flowrate and count up and down on the 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 ABS or aluminum enclosures for harsh industrial
surroundings,
 ability to process all types of flowmeter signals,
 transmitting possibilities with analog / pulse and communication (option) outputs.
Flowmeter input
This manual describes the unit with a pulse type input from the flowmeter "-P version".
One flowmeter with two passive or active pulse, Namur or coil signal outputs 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
 Configurable pulse output: a scaled pulse mirroring a certain totalised quantity. Maximum
frequency 60Hz.; the pulse length can be set from 7,8msec up to 2 seconds,
 Negative / positive pulse output indication,
 Configurable passive linear 4-20mA analog output with 10-bits resolution mirroring the actual
flowrate. Flowrate levels as well as the minimum and maximum signal output can be tuned.
