Mounting on a Nozzle
If the maximum level to be measured falls within the blocking distance, the transmitter
must be mounted on a nozzle. Please note that if product enters the blocking distance,
the device will not measure correctly.
• No buildup should form in the nozzle.
• The recommend nozzle dimensions are limits, within which the nozzle can vary. Select
as big a nozzle diameter as possible
, but keep
the height as small as possible
• The inner surface of the nozzle should be as smooth as possible (no edges or welding
seams).
• Interference echoes caused by the nozzle can be suppressed by the echo suppression
function when a display is used for operation (see page 25).
