1. INTRODUCTION
1.1. 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.
