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
function in Supervisor > Basic Parameters to keep the effects of multiple reflections to a
minimum. For more data, refer to Function description on page 58
(2. Supervisor).
Bypass chambers
Installation next to tanks containing one liquid and foam
• The top process connection of the bypass chamber must be above the maximum level of liquid.
• The bottom process connection of the bypass chamber must be below the lowest measured level of liquid.
Installation next to tanks containing more than one liquid
• The top process connection of the bypass chamber must be above the maximum level of liquid.
• The bottom process connection of the bypass chamber must be below the lowest measured level of liquid.
