Any material in the duct must be free flowing for the sensor to be able to measure
accurately.
Best results are achieved when:-
•
The sensor head is at 40º from the material flow.
•
Material flow above the sensor is ducted to provide a smooth, constant flow.
•
Flow rate is controlled down-stream of the sensor thus allowing material to back-up over
the sensor and provide a constant material depth of at least 100mm.
•
All ducting is smooth with no edges where the flow can be interrupted.
•
A material flow rate of minimum 1kg/sec (3.54 ton/hour (long)) is used.
Figure 9 shows the Hydro-Mix HT integrated into a duct. The outlet dimensions will need to be
adjusted to suit each application to provide a suitable flow rate and a minimum of 100mm of
material above the sensor.
To achieve the required 100mm of material above the sensor and a stable flow the Hydro-Mix
HT should be installed in an overflow ducting system. This allows any additional material not
required to maintain 100mm in front of the sensor to overflow, reducing the possibility of a
blockage.
