Applications
The DCR Controller can be configured for four different types of
applications. They are:
• Distance: Measuring the distance to an object
• Volume: Determining the volume, or level of a product in a tank
• Differential: Calculating the differential measurement between two levels
or measurements
• Open Channel Flow: Taking flow rate measurements over a weir or flume
DISTANCE
Measuring the distance to a target is the most basic application. The DCR
Controller will do this without any special settings. The zero distance point is .5
inches behind the face of the DST-X002 and DST-X003, at the transducer face
on the DST-X001.
Example 5: Distance Measurement
A batch plant operator needs a display to show the level of rock in a hopper 5
meters deep.
To program the DCR-1003, 1004 for this application, the following values
must be entered in the modes indicated. Many of them are the same as the
preset values but are shown again for example purposes.
MODE VALUE DESCRIPTION
Operation
1 3 Set units to meters because the output is to be displayed in
meters
2 .0 Change the display so that it will have a 10 cm resolution
3 1 Select distance monitoring for application
4 80 Adjust percent of sensitivity with 100 being maximum
5 .60 Do not set closer than the minimum blanking spec. for the DST
sensor.
