Figure 3-14: Horizontal cylindrical tanks
1 The device is installed without a stilling well. There are multiple reflections. Refer to the CAUTION! that follows.
2 The device is installed in a stilling well and measures correctly.
CAUTION!
If the device is installed in horizontal cylindrical tank that contains a high dielectric constant
liquid without a stilling well, do not put it on the tank centerline. This will cause multiple
reflections and the device will not measure accurately. Use the 2.5.8 Multiple Reflections
