4.1 Pipe component and transducer
Inlet and outlet runs must be provided to avoid negative effects on the measuring accuracy, These
steadying run lengths make sure that disturbances of the flow profile are eliminated before they can reach
the actual measuring point at the transducer. Straight, undisturbed pipe lengths are used as steadying
run lengths, their length depends on the type of the inlet run disturbance.
4.1.1
Recommended steadying run lengths for inlet run disturbances
The inlet and outlet run lengths are stated as multiples of the pipe diameter D.
Recommended insatallation requirements according to DIN EN ISO 5167-1
