Flow
• Ability to process all types of flowmeter signals:
Reed-switch, NAMUR, NPN/PNP pulse, Sine wave
(coil), Active pulse signals, (0)4 - 20mA, 0 - 10V DC.
Temperature
• PT100 - 2 or 3 wire.
• (0)4 - 20mA / 0 - 10V DC.
Applications
• The F-Series is your first and safest choice for field
mount indicators in safe and hazardous area
applications. Especially in harsh weather
conditions like rain, snow, salty atmosphers and
temperatures between -40°C up to +80°C
(-40°F up to 176°F).
• Applications where nett flow calculation at base
conditions is desired without the influence of
thermal product expansion. For DIN panel mount
indicators, check our D-Series.
General information
Introduction
Signal input
The flowcomputer Model F126-EL has been
developed to calculate corrected liquid volume at
normal conditions for generic products.
The corrected volumetric flow is calculated by
using the thermal expansion coefficient algorithm
stored in the flowcomputer. The reference
temperature can be defined as desired, e.g. 15°C,
20°C or 60°F. A typical application is flow
calculation of water, fuel or chemicals at base
conditions.
The flowcomputer measures the uncorrected
volumetric flow and actual line temperature.
The F126-EL will accept most pulse and analog
input signals for flow. The analog flow input is
available with lineair and square root calculation
and even as 4 - 20mA input loop powered. For
temperature measurement, 2 or 3 wire PT100
elements or sensors with a (0)4 - 20mA / 0 - 10V
DC output signal can be used.
Communication
Display
All process data and settings can be read and
modified manually or through the Modbus
communication link (RS232 / RS485).
Full Modbus functionality remains available for the
Intrinsically Safe version (TTL).
The display has large 17mm (0.67”) and 8mm
(0.31”) digits which can be set to show flow rate,
total and temperature. On-screen engineering
units are easily configured from a comprehensive
menu. The accumulated total can register up to 11
digits and is backed-up in EEPROM memory every
minute.
Hazardous areas
This model has been ATEX and IECEx certified
Intrinsically Safe for gas and dust applications,
with an allowed ambient temperature of
-40°C to +70°C (-40°F to +158°F). A flame proof
Configuration
All configuration settings are accessed via a
simple operator menu which can be password
protected. Each setting is clearly indicated with an
alphanumerical description, which avoids
confusing abbreviations and baffling codes. Once
familiar with one F-series product, you will be able
to program all models in the series without a
manual. All settings are safely stored in EEPROM
memory in the event of sudden power failure.
Ex d enclosure with ATEX certification is also
available.
Enclosures
Various types of enclosures can be selected, all
ATEX and IECEx approved. As standard the F126-EL
is supplied in an GRP panel mount enclosure,
which can be converted to an IP67 / NEMA Type4X
GRP field mount enclosure by the addition of a
back case. Most popular is our rugged aluminum
field mount enclosure with IP67 / NEMA Type4X
rating. Both European or U.S. cable gland entry
threads are available.
Analog output signal
The calculated flow rate is re-transmitted with the
(0)4 - 20mA or 0 - 10V DC output signal. The
output signal is updated eight times per second
with a filter function being available to smoothen
out the signal if desired.
The output value is user defined in relation to the
flow rate, e.g. 4mA equals to 15Nm3/Hr and 20mA
equals to 2000Nm3/Hr. The output signal can be
passive, active or isolated where the passive
output type will loop power the F126-EL as well.
Overview application F126-EL
Pulse output
Pulse output
The scaleable pulse output, reflects the count
on the accumulated display. The pulse length is
user defined from 0.001 second up to 9.999
seconds. The maximum output frequency is
500Hz. The output signal can be passive NPN,
active PNP or an isolated electro-mechanical
relay.
