OPTISOUND 3010 C can be used from tube diameters of 40 mm
(1.575 in).
Avoid large gaps and thick welding joints when connecting the tubes.
Generally carry out a false signal suppression.
Measurement in a standpipe is not recommended for extremely
adhesive products.
The short examples give you introductory information on flow
measurement. Detailed planning information is available from flume
manufacturers and in special literature.
