The feedwater pump discharge pressures can vary between 875 and 1000 psi depending upon boiler demand. Differential pressure between the two points can be up to 200 psi, (or even higher in system upset conditions). This differential pressure must be accurately measured, without regard to the 800 psi and above changing boiler drum static pressure.
