ABSTRACT:
A pressure memory device is used in conjunction with a pressure gauge to measure the highest or lowest liquid pressure in a system and to retain that measurement. The device comprises a manifold having a through bore with a check valve disposed therein. By connecting a pressure gauge to one end of the through bore and coupling the other end of the through bore to a fluid system, the check valve will trap fluid between the check valve and the pressure gauge.
