<P>PROBLEM TO BE SOLVED: To provide a simpler and potentially less expensive method for monitoring accurate fluid metering from a gear pump. <P>SOLUTION: A gear pump includes a housing with an inlet port 80 for receiving a viscous fluid and an outlet port 94 for discharging the viscous fluid. A driven gear 30 and an idler gear 32 are each mounted for rotation in the housing. An inlet space is in fluid communication with the inlet port, and an outlet space is in fluid communication with the outlet port. A gear 60 that is a flow indicating element is located in the housing and mounted for rotation independently of the driven gear and the idler gear. The flow indicating element is configured to be rotated by the viscous fluid to indicate when the fluid moves from the inlet port and inlet space to the outlet space and outlet port. Methods of indicating flow of viscous fluid through a gear pump are also provided. <P>COPYRIGHT: (C)2013,JPO&INPIT |
