SYSTEM DESCRIPTION OF THE F113-A

Functions and features
The flowrate / totalizer model F113-A is a microprocessor driven instrument designed to display flowrate,
total and accumulated total as well as the monitoring of the flowrate for high / low values.
This product has been designed with a focus on:

ultra-low power consumption to allow long-life battery powered applications (type PB),

intrinsic safety for use in hazardous applications (type XI),

several mounting possibilities with GRP or aluminum enclosures for harsh industrial surroundings,

ability to process all types of flowmeter signals,

transmitting possibilities with analog / pulse / alarm and communication (option) outputs.
Flowmeter input
This manual describes the unit with an analog type input from the flowmeter "-A version". Other versions
are available to process pulses or 0-10V flowmeter signals. One flowmeter with a (0)4-20mA signal output
can be connected to the F113-A. To power the sensor, several options are available.
Standard outputs

Max. four configurable alarm outputs: flowrate alarm, high-, low-, high-high- or low-low-flowrate alarm.
Switched as long as the flowrate is too high or too low.

Max. four configurable pulse outputs: a scaled pulse mirroring a certain totalized quantity. Maximum
frequency 60Hz.

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.
Configuration of the unit
The F113-A was designed to be implemented in many types of applications. For that reason, a SETUP-
level is available to configure your F113-A according to your specific requirements.
SETUP includes several important features, such as K-factors, measurement units, signal selection etc.
All setting are stored in EEPROM memory and will not be lost in the event of power failure or a drained
battery. To extend the battery-life time (option), please make use of the power-management functions as
described in chapter 3.2.3.
A backup of the total and accumulated total in EEPROM memory is made every minute.
Display information
The unit has a LCD with (optional) backlight to show the process information, status and alarm messages.
Options
The following options are available: isolated or active 4-20mA / 0-10V / 0-20mA analog output, full
Modbus communication RS232/485 (also battery powered), intrinsic safety, mechanical relay or active
outputs, power- and sensor-supply options, panel-mount, wall-mount and weather-proof enclosures,
flame proof enclosure.
Backlight
When a backlight is available, the brightness can be tuned as desired. For battery and loop powered
applications the backlight will not function.
