Abstract (en)
[origin: EP1762138A1] A method for compensating for changeover in a reciprocating pump having a check valve, a displacement transducer and a valve at the outlet of the pump, includes the steps of: closing the fluid valve as the pump reaches changeover, to allow the pump to compress any gases and positively close the check valve; and, when the pump stalls, opening the fluid valve. Any travel and imputed flow during the portion of the cycle when the valve is closed is disregarded.
