There is a permanent magnet on the end disc of the turbine shaft which induces a
voltage pulse in the Wiegand sensor with every rotation. This pulse is supplied to the
counter of the meter head, which detects the operating volume flow directly as a main
totalizer and determines the gas volume flowing through the meter by adding up the
pulses and division by the meter factor (number of pulses per m
ume is shown in the display of the TME400.
Note
The unchanged signal frequency of the sensor element is output at the HF
output.
The LF output transmits this HF frequency with a variable scaling factor (chapter
4.3.3.1 Volume / Meters).

1.4.2.
Turbine meters from RMG are equipped with connecting flanges. For a secure con-
nection, the connection dimensions of the flanges of the pipelines to be connected
must match the connection dimensions of the flanges of the device.
•
ANSI pressure levels: flange connection dimensions correspond to the
standard ASME B 16.5.
•
DIN pressure levels: flange connection dimensions correspond to the
standard DIN EN 1092.
