Dripless shaft seal flow meter. Good or bad idea?

The boat came with full flow meters and needle valves on the water feed for the dripless shaft seals. Great in theory but I'm thinking over engineered. One of the flow meters failed last time out. The failure was the indicator stuck "down" so no water flow to the shaft seal. This could have caused the shaft seal to burn up. So I'm thinking of removing the flow meters and needle valves.

I'm asking for opinions on using flow meters on the shaft seal water feed. How many have flow indication of any kind on your dripless seals? Seems like overkill to me. I'm new to dripless always having had old fashioned stuffing boxes in the past.
