ToughSonic® LVL Family Sensors - Installation & Operating Instructions
Mechanical Details
Installation
Dimensions are inches [mm]. Sensor measurements are
the distance between the ultrasonic transducer face (the
bottom of housing shown below) and the target
material. The lower threads vary by model:
Precautions

1.5-in Parallel: LVL-100 and LVL-300

2.0-in Parallel: LVL-500
 Keep unintended targets from the transducer’s field
of view. Keep the beam pattern in mind.
 Keep the transducer away from ultrasonic noise
sources, such as pressurized air nozzles.
 Do not allow material to build up on the sensor face
or sensor performance may suffer.
Orientation
Max. Width
Orient the sensor perpendicular to the liquid surface or
target object for best results as shown in Figure 3.
Upper
Threads
1-in. NPT
Length
Lower Threads
2-in. parallel
or
1.5-in. parallel

Face
1.5 in. parallel: 1.9 [47mm]
2.0 in. parallel: 2.3 [58mm]

Ultrasound energy must reflect back to the sensor or the
sensor will not detect the target, and may detect a later
multipath echo (which would “measure” as a lower tank
level).
Location and Obstacles
The sensor mounting location should be chosen so there
are no obstacles in the beam path that reflect the
ultrasound beam back to the sensor.
