The High-Performance Solution

The TWC 9000 is a universal coriolis meter converter
suitable for a wide range of applications and installations.
A common platform allows easy selection for the output
options required, and is suitable for mountUUing in various
housing configurations.

The TWC 9000 is also suitable for all current and future
mass flow sensors. The split architecture solution for the
mass flow family ensures maximum security and redundant
back up of calibration parameters, should a failure occur.
There is no need for reprogramming after a failed unit is
replaced.

The TWC 010 implements all sensor drive and signal

evaluation functions into an integrated front-end electronics
module permanently fixed to the sensor.
Figure 1 – VersaFlow TWC 9000 Converter
This cost effective solution eliminates unwanted and
expensive I/O and display functions associated with
traditional signal converters and transmitters, and is
designed for use in OEM systems or packages where a
PLC or DCS is already used for other functions.

The TWC 010 Modbus communications is a simple 4-wire

(1 pair data and 1 pair power) interface which is all that is

Mass Flowmeter Product Family

All meters consist of a sensor and a converter, which may be mounted integral to the sensor, or remotely, either with a field
mount kit, a wall mount housing or a 19" rack mount module.

A sensor mount converter (TWC 010) with a Modbus® output only is also possible for OEM manufacturers or where the user
does not require a converter with analogue outputs.

The TWC 9000 with standard basic I/O covers almost all applications, having 4 I/Os:
 active/passive current output (+HART)

 passive pulse/status output

 passive status output

 passive status output / control input

The I/O-module combination is thus 1-0-0 (see above).

The TWC 9000 with modular I/O can be tailor-made to any application:
 Suppose you require a converter with passive pulse output and 3 passive current outputs. The I/O-module
combination then becomes B-B-B.

 Suppose you require a converter with 2 active pulse/status outputs. The I/Omodule combination then becomes
either 4-C-8 or 8-C-8 (depending on whether active or passive current output is required). The latter ’8’ indicates
that 1 additional module can be added in the future.

 Suppose you require a converter with Profibus PA communication, 1 active current output and 1 passive control
input. The I/Omodule combination then becomes D-A-K.

For I/O-module combinations, not described in the overview on the right, please consult HONEYWELL.
