Example 3: Using a Single Viper Transducer to Measure 2 Different
Interface Levels.
The Pulsar SF2 Integrator can be used to monitor both the Rag or FLOC levels
and the Settled Sludge or RAS levels simultaneously using only one Viper
Transducer.
This feature gives the user the ability to monitor and control the RAS level
application by monitoring the settled sludge, but also prevent damaging FLOC
spillage to the local water course by monitoring the less dense Rag levels.
To achieve this we utilise Point number 2 in addition to Point number 1. Both
points will display the same profile but different service parameters can be
applied thus setting Point 1 to monitor the RAS layer and Point 2 the FLOC
layer.
It is required to set Point 2 Allocation in the Application menu (P1103) To 0 =
Transducer 1.
Fig 1.
The above profiles show the unit differentiating between the two echoes. In this
instance point one is set to pick the largest echo and point two is set to pick the
first echo (see SF2 Service Manual for details).
Each 4-20ma can be independently set to track both interfaces.
All relays can be independently set to give control or alarms on both points.
