Use of clamp-on (externally mounted) ultrasonic flow-metering techniques for fluid applications. Guide Ingestion-build-239834 Steel indenter balls are allowed1 Scope This British Standard identifies factors, including installation effects, pipe work and fluid effects, operational effects and supplier specific effects, which are likely to affect the performance of clamp on (externally mounted) ultrasonic flow meters This includes hybrid spool type clamp on meters where the clamp on transducers are permanently mounted to a spool piece of precisely known physical dimensions. In doing so it also identifies
