Prowirl 70
Measuring System
Applications
The Prowirl vortex flowmeter measures
the volumetric flow of fluids with widely
differing characteristics:
•
Saturated steam
•
Superheated steam
•
Gases
•
Low-viscosity liquids
Applications include:
•
Energy production
•
Chemical and petrochemical industry
•
Food processing
•
OEM
Prowirl measures the volumetric flow at
operating conditions. If the process
pressure and temperature are constant,
Prowirl can be programmed to display
the flow rate in mass, thermal, or cor-
rected volume units.
In case of varying process conditions,
the universal Compart DXF 351 flow
computer calculates these values contin-
ually on the basis of signals from Prowirl
and additional pressure and/or tempera-
ture transmitters.
Measuring System
A measuring system consists of:
•
Prowirl 70 transmitter
(compact or remote)
•
Prowirl W, F, H, or D meter body
(see page 3)
The high performance, universal Prowirl
70 transmitter can be freely combined
with the various, proven meter body
styles. This guarantees flexibility when
matching a complete meter to specific
industrial process conditions.
Prowirl 70 Transmitter
The new Prowirl 70 transmitter has the
following features:
•
Microprocessor-controlled
•
Self-monitoring and diagnosis of
electronics and sensor
•
Separate wiring compartment
•
IP 65 protection type
•
Built-in electromagnetic interference
immunity (EMC)
•
Programmable meter body thermal
expansion coefficients
•
4...20 mA current output
•
Open collector output, configurable
for pulses, alarm or limit switch
(not with Ex d version)
•
Optional digital display with bargraph
for rate and total
Local Programming
All functions can be set and all values
can be read at the meter using four
pushbuttons, even in hazardous areas,
and without opening the housing.
Prowirl is delivered factory-programmed,
but viewing or selection of the individual
functions is easily done using a simple
menu and the local display. Examples
are:
•
Engineering units
•
Current output functions
•
Open collector functions
•
Display mode (local)
•
System parameters
Digital Communication
•
SMART technology permits remote
programming of Prowirl 70 via HART
protocol, using the HART DXR 275
handheld.
•
With the E+H Intensor protocol,
Prowirl 70 can be run with the
Commutec system, making the system
integration to Modbus, Profibus and
FIP systems possible.
Using the Commuwin II program or a
Commubox modem, the measured
values and functions can be read or
changed via a PC.
