Deriving Boolena expressions for a given tank system
Not what you're looking for?
A liquid tank system is explored and using a number of input sensor conditions boolena expressions for and overfill alarm OV and an Empty alarm EP are derived for the conditions/scenarios given
The boolean expression for an Overflow fill alarm OV which is active
1. if the input flow rate sensor is high while the output sensor is low, the pressure is low and the level is high
2. If both flow rates are high while the output flow rates are low and the pressure is low
Is derived.
Also the EP = Empty alarm boolean expression is derived for conditions where EP is high when
1. Both input rates are low, the level is low and the output flow rate is high
2. If either input flow rate is low, the output flow rte high and the pressure in the tank is high
