This chapter outlines the essential elements of provers that do@ and also do not@ accumulate a minimum of 10@000 whole meter pulses between detector switches@ and provides design and installation details for the types of displacement provers that are currently in use. The provers discussed in this chapter are designed for proving measurement devices under dynamic operating conditions with single-phase liquid hydrocarbons. These provers consist of a pipe section through which a displacer travels and activates detection devices before stopping at the end of the run as the stream is diverted or bypassed.
