1.3. Overview of versions

Description

1.3.1.
The TME400-VM is a turbine meter which is used for volume measurement of the
operating 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 in internal archives. The re-
sult is registered in an electronic meter.
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 VM has a serial RS 485 interface for digital
data readings and parameterization. The TME400-VM is used in non-custody-
transfer applications.
The TME400-VMF (MID) is the turbine meter for custody-transfer applications and
has an equivalent function and operating method to the TME400-VM. The essential
difference is the 2-channel measuring head version. It is used in custody-transfer
applications.
