Example calculation for the pressure loss of a turbine meter:
TME400 in DN 150:
Q
m
= 650 m³/h
r
= 1.3 kg/m³ (natural gas at 600 mbar overpressure)
Z
p
(TME400) = 5040 (see the table above)
Calculation:
Þ
= 5.5 mbar

Putting the device into operation
Note
You receive the TME400 parameterized and calibrated according to your
specifications, so that no additionally settings are generally required.
However, check whether these settings match your specifications; check the settings
of the pulse width, the frequency reducer and the settings of the current output (for
versions with current output).
Bring all totalizers to the meter status which you desire. (see
chapter 4.2 Program-
ming ).
Note
Parameters can be changed exclusively with the device open.

Maintenance / lubrication
The TME400 is equipped with permanently lubricated bearings up to a nominal
diameter of DN150 as standard. Nominal diameters of DN200 or higher are provided
with an integrated lubricating device. Optionally, the TME400 can also be equipped
with the "small oil pump" lubricating devices for DN25 to DN150 versions.
The type of lubricating device and the lubricant requirement depend on the nominal
diameter and the pressure level:
