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 3-19: 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
2.3.12 Multiple Reflections 2.3.12 Multiple Reflections 2.3.12 Multiple Reflections
function in Supervisor > Basic Parameters Supervisor > Basic Parameters Supervisor > Basic Parameters Supervisor > Basic Parameters to keep the effects of multiple reflections to a
minimum. For more data, refer to Function description on page 68 (2. Supervisor).
