Horizontal cylindrical tanks
If the device:
• is for a horizontal cylindrical tank,
• is in a metallic tank,
• measures a product with a high dielectric constant and
• is on the centerline of the tank,
we recommend that you install it in a stilling well.
Figure 3-8: 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 multiple reflections
