Description
The
TME400-VC
is a turbine meter which is used for volume measurement of the op-
erating volume of non-aggressive gases and burnable gas. The operating volume
flow is determined based on the turbine speed, which is scanned by means of a Wie-
gand or Reed sensor element and then added together. An optional 2-channel meas-
uring head version can be implemented for inspection purposes, particularly for use
in custody-transfer applications. The result is registered in an electronic meter. This
operating volume flow is determined for the present pressure and temperature condi-
tions, with are also detected. The integrated volume corrector of the TME400-VC en-
ables calculation of the standard volume flow from the operating volume flow with the
pressure and temperature data (
V
olume
C
orrector). Special gas properties can be
factored in using different gas models for correct gas status determination. The
measured operating volume and / or the calculated standard volume are added up in
internal archives.
There are a high-frequency (HF) and a low-frequency (LF) output, where the HF out-
put is preferably used as a flow sensor for control tasks and remote transmission. In
addition to these outputs, the TME400 VC has a serial RS-485 interface for digital
data readings and parameterization. The TME400-VC is used in
non-custody-trans-
fer
applications.
The
TME400-VCF
(MID) is the version of the TME400-VC for
custody-transfer
ap-
plications. The device can be activated via the same outputs.
The
TME400-VCF
(MID) is the turbine meter with volume corrector for custody-trans-
fer applications and has an equivalent function and operating method to the TME400-
VC. It is used in
custody-transfer applications
.
