SYSTEM DESCRIPTION OF THE F131-P
Functions and features
The batch controller model F131-P is a microprocessor driven instrument designed for batching and
filling of small batch sizes up to large quantities as well as displaying the flowrate, total and
accumulated total.
This product has been designed with a focus on:
ultra-low power consumption to allow long-life battery powered applications (option PB),
intrinsic safety for use in hazardous applications (option 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". Other
versions are available to process (0)4-20mA or 0-10V flowmeter signals.
One flowmeter with a passive or active pulse, Namur or coil signal output can be connected to the
F131-P. To power the sensor, several options are available.
Standard outputs
Two transistor or relay (option) outputs: for two-stage control or one stage control with pulse
output. The configurable pulse output offers a scaled pulse mirroring a certain totalised quantity.
Maximum frequency 60Hz.; the pulse length can be set from 7,8msec up to 2 seconds.
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.
