Flow meter FC01-Ex Flow meter FC01-Ex
Ex atmosphere - Definitions and mounting instructions 1 Ex atmosphere - Definitions and mounting instructions 1
1 Description
The flow meter FC01-Ex is designed to provide stationary monitoring, detection and indication of flow
speed, flow volume and medium temperature of liquids, gases and powders with evaluation of the
measuring data of the calorimetric monitoring head CST-Ex with separate EC type test certificate.
In addition the FC01-Ex provides power to, and processes output signals from the intrinsically
safe type CST-Ex monitoring head. Connections between the intrinsically safe area and the non-
intrinsically safe area are via safety barriers. The FC01-Ex control unit must be sited outside the
ex area.

2.1 Information on explosion protection
The flow monitor FC01-Ex is an "associated electronic apparatus”. It has been designed accord-
ing to the directives the European standards EN 50014 and EN 50020 to type protection:
II (1) GD [EEx ia] IIC.
It carries the Ex type test certification number ZELM 02 ATEX 0117.
The monitoring head CST-Ex is an intrinsically safe apparatus. It has been designed for use as
prescribed in explosive atmospheres to directive 94/9/EC and is meant for use in applications of
the equipment group II, category 1 (gas zone 0 or dust zone 20).
It has been designed according to the directives of the European standards EN 50014, EN 50020,
EN 50281-1-1, EN 50284 and EN 1127-1 type of protection:
II 1/2 GD T130°C IP67 EEx ia IIC T4.
It carries the Ex type test certification number ZELM 02 ATEX 0116 X.
