Stilling wells: horizontal cylindrical tanks
We recommend that you install the device in a stilling well 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.
Figure 3-18: 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 2.3.12 Multiple Reflections function in
Supervisor > Basic Parameters to keep the effects of multiple reflections to a minimum. For
more data, refer to Function description on page 65 (2. Supervisor).
