6 Functional Description
6.1 General
The OCM Pro CF is a stationary measurement system for flow measurement
and storage of the detected measurement data. Type M4 additionally allows to
use a 3-step controller to drive a slide valve or similar flow control actuator. Fur-
thermore up to 4 external measurement values can be stored. Wall mount en-
closure units can be accessed remotely using the TCPIP protocol via Internet.
The device is designed to be used for measurements primarily in slight to heavy
polluted media with various compositions. It can be operated in part filled and full
channels and pipes with various shapes and dimensions.
Important Note
The method of flow velocity investigation is based on the ultrasound reflection
principle. Hence, it is indispensable for the system to work that there are
particles in the water, which are able to reflect the ultrasonic signal sent by the
sensor (dirt particles, gas bubbles or similar). Alternative the surface velocity
can be measured by using an OFR radar sensor. This sensor must not get in
contact with the medium.
The OCM Pro CF type S4 either uses a POA or a CS2 sensor which simultane-
ously determines flow velocity and flow level. Alternatively, a CSM sensor in
con-junction with the electronic box EBM may be connected, which however
merely is a flow velocity sensor.
Type M4 allows to connect up to 3 POA or CS2 sensors or type EBM electronic
boxes with type CSM sensors at the same time to accurately detect the flow ve-
locity at one common measurement point.
In order to connect a type OFR surface radar the first sensor input can be used.
Use a transmitter type R4 for this kind of connection.
