Features
The CIP Monitor utilizes sophisticated filtering techniques that virtually eliminates interference from background noise. Table 2
below shows a comparison of features.

Pressure and Radar based solutions are deficient for the following reasons:
- Must invade the tank
- Create shadows that may compromise the CIP process
- May introduce particulate matter from the sensor
- Monitoring is intermittent
- Detection reliability subject to sensor sensitivity, e.g., low pressure may detected as normal pressure
- Maintenance/repair of the sensor requires taking the tank off-line
In addition to the above deficiencies, RF solution is not passive, allowing for the introduction of energy into the tank, which may interact with the cleaning fluid.
Acoustic analysis is clearly the preferred approach. In addition to overcoming the above mentioned deficiencies of pressure and RF sensors, the acoustic
sensor is:
- Not limited too tank size, shape, mounting configuration, internal construction, or the number of CIP devices.
- In all cases is capable of isolating the sound signatures of individual CIP devices located with in the tank.
- Capable of detecting:
- Rotation failure
- Frequency of rotation
- Variations in spray pressure
- Clogged nozzles, respective to each device
