Downlook Ultrasonic Sensor
4.10.1.2 Mounting the Ultrasonic Sensor
Note: To prevent mechanical
vibration ensure that the supplied
isolation washers are installed as
shown in Figure 34.
Several brackets are available for mounting the sensor to a fixed location such
as a wall or floor. See Figure 34 and Figure 35. For mounting options see
Parts and Accessories on page 157. Each bracket utilizes the ¾ in. (1.9 cm)
NPT connector on the sensor to secure the sensor to the bracket. Always
level the sensor using a level. The maximum water level must be below the
deadband to ensure accurate readings.
The sensor is “blind” to anything closer than the deadband and will stop
reading level when the distance is shorter than that.
