built-in sensor or 310 remote ultrasonic sensor

The Minimum Blanking Distance is the distance from the
bottom of the sensor to the liquid surface at the highest expected
level. Depending on the elevation of the sensor, this value may be
increased to help ensure that echoes read by the flowmeter come
only from the surface of the flow stream, and not off the walls or
sides of the channel.
The Maximum Blanking Distance is the distance between the
bottom of the sensor and the bottom of the channel (i.e., zero
level). A larger value than calculated can be entered.
If using the LaserFlow Ex module with the 310 remote ultrasonic
sensor and horizontal sensor mounting bracket, the maximum
blanking distance is the distance between the bottom of the
mounting bracket and the bottom of the channel.
