ParaFlow sensor measuring surface velocity
Surcharge Peak Velocity Sensor
The Surcharge Peak Velocity sensor resides in the angled, front
portion of the sensor in front of the ultrasonic depth parabolic
cavity. It measures the velocity of the flow during surcharge
conditions using the same methodology as the Peak Combo
Velocity Sensor. Therefore, it will measure velocity only when the
pipe is full.
Surcharge Pressure Depth Sensor
The surcharge pressure depth sensor in the ParaFlow Sensor
measures pressure depth using the same technique as the other
combo sensors, except from the top of the pipe. Since it can
provide an accurate depth only when submerged, the data from this
sensor is useful only under full-pipe or surcharge conditions. The
ParaFlow Sensor supports pressure measurement of 0 - 10 PSI (0 -
0.68 Bar.
Peak Combo Sensor
The Peak Combo Sensor with a standard 35-foot (10.6-m) or 100-
foot (30.5-m) cable (ADS p/n 8K-CS4-XX-35/1H) typically mounts
at the bottom of the pipe and measures ultrasonic depth, pressure
