SYSTEM DESCRIPTION
Functions and features
The flow computer, model F126-P-EL-TP is a microprocessor driven instrument for the
calculation of
the flow rate from a liquid medium with respect to temperature and pressure.
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 and temperature input
This manual describes the unit with a pulse input from the flowmeter. The F126-P has also a PT100
temperature input. 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 F126-P. To power the sensor, several options are available.
Standard output
Pulse output to transmit a pulse that represents a totalized quantity as programmed.
Linear (0)4-20mA or 0-10V analog output to represent the actual flow rate as programmed. The
(0)4-20mA or 0-10V signal limits can be tuned.
