SYSTEM DESCRIPTION OF THE F012-A

Functions and features
The flow rate indicator / totalizer model F012-A is a microprocessor driven instrument designed to
display flow rate, total and accumulated total.
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 GRP, aluminum or stainless steel 316L enclosures for
industrial surroundings,
▪
ability to process all types of flowmeter signals.
Flowmeter input
This manual describes the unit with an analog (0)4-20mA input type from the flowmeter "-A version".
Other versions are available to process pulse or 0-10V flowmeter signals.
One flowmeter with a passive or active (0)4-20mA signal output can be connected to the F012-A. To
power the sensor, several options are available.
Configuration of the F012-A
The F012-A has been designed to be implemented in many types of applications. For that reason, a
SETUP-level is available to configure your F012-A according to your specific requirements.
It includes several important features, such as span, measurement units, signal selection etc. All
setting are stored in EEPROM memory and will not be lost in the event of power failure. To extend
the battery-life time, please use of the power-management functions as described in chapter 3.3.5.
Display information
The F012-A has a large transflective LCD with all kinds of symbols and digits to display measuring
units, status information, trend-indication and key-word messages.
Running and accumulated totals can be displayed with the 8mm and 17mm digits.
A backup of the total and accumulated total in EEPROM memory is made every minute.
Options
The following options are available: intrinsic safety, power- and sensor-supply options, panel-mount,
wall-mount and weather-proof enclosures, flame proof enclosure and LED backlight.
