Surface Combo Sensor
Ultrasonic Depth Sensor
This sensor first transmits an ultrasonic signal downward from one
of the crystals on the sensor face that bounces off the flow surface
and returns to the other crystal. The monitor measures the travel
time elapsed between transmission and reception of the reflected
sound signal. Based on the elapsed time and the speed of sound, the
monitor determines the range. The range represents the distance
between the sensor face and flow surface. The monitor calculates
the depth of the flow by subtracting the range from the pipe
diameter. It compensates for the speed of sound in the air using the
temperature recorded by a temperature sensor housed within the
ultrasonic depth sensor.
The ultrasonic depth sensor is located in the front, horizontal
portion of the sensor and has two downward-facing ultrasonic
crystals covered with a clear, moisture-shedding Teflon
®
coating.
