SYSTEM DESCRIPTION
Functions and features
The flow rate / totalizer, model F112-P is a microprocessor driven instrument designed to linearize
the flowmeters flow curve and to show the flow rate, the total and the 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 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.
One flowmeter with a passive or active pulse, Namur or sine wave (coil) signal output can be
connected to the F112-P. To power the sensor, several options are available.
Standard outputs
▪
Pulse output to transmit a pulse that represents a linearized totalized quantity as programmed.
▪
Linear (0)4-20mA or 0-10V analog output to represent the actual, linearized, flow rate as
programmed. The (0)4-20mA or 0-10V signal limits can be tuned.
