ParaDepth Sensor
This sensor can be mounted at the crown
(top) of the pipe or in the manhole structure using the ADS Topside
Retrieval System. It contains a downward looking ultrasonic depth
sensor and air temperature sensor. It differs from the standard
Ultrasonic Depth Sensor listed below in that it leverages the
parabolic reflector design developed in the ADS Long Range Depth
sensor to more accurately and reliably measure flow level. It also
contains an Accelerometer to measure sensor rotation and slope for
ease and accuracy of installation.
x
ParaFlow Sensor This sensor can be mounted at the crown (top)
of the pipe or in the manhole structure using the ADS Topside
Retrieval System. It contains a downward looking ultrasonic sensor,
a surcharge pressure depth sensor, a surface velocity sensor, a
surcharge velocity sensor and an air temperature sensor. It differs
from the standard Surface Combo Sensor listed below in that it
leverages the parabolic reflector design developed in the ADS Long
Range Depth sensor for both depth and velocity to more accurately
and reliably measure flow level and velocity. It also contains an
Accelerometer to measure sensor rotation and slope for ease and
accuracy of installation.
x
Peak Combo Sensor This sensor, which mounts at or near the
bottom of the pipe, contains an upward-looking ultrasonic depth
sensor, a continuous wave Doppler peak velocity sensor, pressure
depth sensor and a water temperature sensor.
x
Surface Combo Sensor
This sensor, which mounts at the top
of the pipe, contains an ultrasonic depth sensor, a surface velocity
sensor, a surcharge peak velocity sensor, surcharge pressure depth
sensor and an air temperature sensor.
x
Ultrasonic Depth Sensor This sensor, which mounts at the top
of the pipe, is a standalone ultrasonic depth sensor and also includes
an air temperature sensor.
The monitor receives the raw flow depth and velocity data from the
sensors based on a defined time interval and then processes the data,
which may involve calculating the flow rate. The monitor memory can
store up to 150 days of data based on logging 6 entities at a 15-minute
sample rate. The storage capacity varies according to the number of
sensors attached to the monitor, the number of entities stored, the rate at
which the entity data is logged, and the functions activated for the
sensors. This data is available to the user for collection, further
processing, analysis, and reporting. These reports include critical
