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 (Volume Corrector). 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.
