TIENet™ 360 LaserFlow™ Velocity Sensor
Section 4 Setup with 2160 LaserFlow Module
Figure 4-6 Blanking distance for LaserFlow with built-in
sensor or 310 remote ultrasonic sensor
4-6
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 flow meter 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 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.
