2 Control buttons for direct
entry
Measuring ranges
The full-scale value can be set at any point between the maximum
possible upper range value 1.15 x Q maxDN and 0.15 x Q maxDN .
Parameter setting
Data can be entered using 3 control buttons (not with the Ex "d"
hazardous area design) or, if the housing is sealed, directly from an
external location using a magnetic pen.
Data is entered in plain text with the display or using digital
communication via the
PA/FOUNDATION Fieldbus.
Flow operating modes
The following operating modes can be selected dependent upon the
design purchased (with or without Pt100):
Fluid medium:
• Operating flow
• Mass flow with constant or temperature-dependent density
Gas/steam medium:
• Operating flow
• Mass flow with constant or temperature-dependent density (at
constant pressure)
• Standard flow with constant or temperature-dependent standard
factor (at constant pressure)
• Mass flow with saturated steam and temperature-driven density
Data backup
Counter readings and parameters for specific measuring points
backed up in FRAM (more than 10 years without supply power) in the
case of shutdown or should the supply voltage fail.
Damping
Configurable from 1 ... 100 s, corresponds to 5 τ.

HART protocol or PROFIBUS
Q v min (low flow)
Configurable between 2 ... 25 % of Q maxDN (max. operating flow per
nominal size). The actual low flow is determined by application and
installation.
Function tests
Software-internal function tests can be used to test individual internal
modules. For the purpose of commissioning and testing, the current
output (4 ... 20 mA design) or the digital output signal (fieldbus
designs) can be simulated in line with flowrates selected by the user
(manual process control). The switching output can also be controlled
directly for the purpose of function testing.
Electrical connection
Screw-type terminals, plug-in connection on PROFIBUS PA (option)
cable gland: -standard., Ex "ib" / Ex "ia": M20 x 1.5; NPT 1/2 " -Ex d":
NPT 1/2"
Ingress protection
IP 67 to EN 60529
Display
High-contrast LCD display, 2 x 8-digit (4 ... 20 mA design) or 4 x 16-
digit (PROFIBUS PA / FOUNDATION Fieldbus design). Shows the
instantaneous flowrate along with the totalized flow or temperature of
the medium (option).
On the 4 ... 20 mA design, the multiplex function enables 2 values
(e.g., flowrate and totalized flow) to be displayed virtually in parallel.
Up to 4 values can be displayed on the fieldbus design.
Switching output terminals 41 / 42
(standard on all designs)
The function can be selected via the software:
- Max./min. alarm for flow or temperature
- System alarm
- Pulse output: f max : 100 Hz; t on : 1 ... 256 ms
Contact type:
- Standard and Ex "d": Optocoupler U H = 16 ... 30 V
- Ex "ib" / Ex "ia": Configured as NAMUR contact
EMC protection
The flowmeter corresponds to NAMUR recommendations NE21.
Electromagnetic compatibility of equipment for process and lab
control technology 5/93 and EMC Directive 2004/108/EC (EN 61326-
1). Note: EMC protection and protection against accidental contact
are limited when the housing cover is open.
