    Has anyone come up with a decent flowmeter or digital pressure gauge to measure water flow based off pressure difference?? Sucks to be stuck in the analog world.....Closed loop, open loop...... I would prefer to have exact readings for water flow.....

    I always just do the old
    BTUH=GPM x 500 x deltaT
    I wonder how far off my numbers would be off compared to a flow meter.

    And back to the question..... getting GPM accurately.... Ya know... the pressure drop through the coax.... Reading it precisely.... Alot of the manufactures have decimals.... ie: 2.3 lb pressure drop= 6gpm..... I want an accurate reading..... any ideas?
