About The InterRanger DPS300

Note:
This microprocessor based level monitor is designed specifically for the
measurement of sludge blanket levels in wastewater clarifiers. A DPS300 level
monitor, and Siemens ultrasonic transducer, accurately monitor the sludge blanket
level without contacting the blanket.
The DPS300 transmits electrical pulses to the transducer. The transducer
converts the electrical pulses to ultrasonic pulses, which are emitted from the
transducer face. The DPS300 measures the time from pulse emission to reception
of the echo from the sludge interface. The time measured, is used to calculate the
distance from the transducer face to the sludge blanket.
The distance calculation is dependent upon the sound velocity through the
wastewater in the clarifier, which is in turn dependent upon the temperature of the
wastewater. The transducer, having an integral temperature sensor, and being
immersed into the wastewater, also monitors the temperature of the wastewater.
The transducer transmits the temperature to the DPS300, where velocity
compensation is applied to the level measurement calculation.
Nominally speaking, the DPS300 is capable of detecting down to 4% solids, in up
to 30m of turbid wastewater, and 0.2% solids in 5 m of clear wastewater.
This material and measurement range versatility is accomplished by using
Siemens patented Sonic Intelligence™. Sonic Intelligence provides high
measurement reliability, regardless of changing conditions in the clarifier.
