Display
By operating any key you can enter the main menu and select the required group including all the
relative display values: Display -> Group -> Group 1. All groups can also be displayed in an
automatic scroll function: Setup -> Display -> Scrolled display (scroll using the arrow under group
6).
If a fault occurs the display automatically changes colour (blue/red). Detailed fault finding and
elimination can be found in the relative chapter of these operating instructions.
An example of steam mass measurement using a Prowirl 77 can be found in the appendix of this
operating manual.

Note!
You will find a further example for a steam mass calculation using a Prowirl 77 in chapter 6.4.1 of
the operating instructions.
Basic application settings
The values shown are only an indication in order to simplify the commissioning of the device, this
means that only the most necessary settings are shown. Special functions (e.g. tables, corrections,
etc.) are not shown.
Water applications
Input values: Flow, temperature 1, (temperature 2)
Only one temperature is required for water heat quantity. A direction signal teriminal is required on
changing flow direction (bi-directional operating mode).
Flow
Pulse/PFM (e.g. ProWirl)
Analog (e.g. Promag) Differential pressure (e.g. Orifice)
Flow input Flow input Special flow meters
Flow meter: Operating volume Flow meter: Operating volume Differential pressure/Orifice/water
Terminals:
– Flow meter with active signal connect to e.g. terminals A10(+)/11(-).
– Flow meter with passive signal select e.g. terminals A10 and connect to terminals A10(-)/82(+). Terminal 82 is 24 V sensor power supply.

Temperature
Select signal type and connect sensor(s) (see example). 2 temperature sensors are required for heat differential measurements.
Application
Application: Medium: water/steam
Liquid application: e.g. water heat difference
Operating mode: e.g. heating (this means inflow warm, return cold)
Allocate sensors for flow and pressure measurement
Allocate installation point, T warm/cold
