SYSTEM DESCRIPTION

Functions and features
The ratio monitor / totalizer model F114-P is a microprocessor driven instrument designed to
calculate, show and monitor the ratio between two flows as well as showing the flow rates and 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 aluminum or GRP enclosures for harsh industrial
surroundings
▪
ability to process all types of flowmeter signals
▪
transmitting possibilities with analog, alarm and communication outputs.
Flowmeter input
This manual describes the unit with a pulse input from the flowmeters. Other versions are available
to process (0)4-20mA signals.
Two flowmeters with a passive or active pulse, Namur or sine wave (coil) signal output can be
connected to the F114-P. To power the sensor, several options are available.
Standard outputs
▪
Max. three configurable alarm outputs: high-, low-, high-high- or low-low-ratio alarm. Switched
as long as the ratio is too high or too low.
▪
Linear (0)4-20 mA or 0-10 V analog output to represent the actual ratio or flow rate as
programmed. The (0)4-20 mA or 0-10 V signal limits can be tuned.
