Fixed the Raven flow control problem, SK21 was spot on with the pinout of the board! Very helpful thank you, I had questioned the motor controller from the RC8 board for the 4 wire harness as the RED wire does not get used. Only the DIR, PWM and ground. The Raven RFM15 flow meter accepts 4.5-16VDC and outputs 5-0 vdc square wave on the black signal wire to the D2 terminal. MAKE sure nobody hooks up the power and ground supply to the meter as it looks on the internet or even as the diagram above from SK21. This is a pin insertion diagram as i’ve included in my photos. Raven tech support mislead me twice to them telling me this was wiring staring at the open end face of the connector on the flow meter. I smoked two sensors and luckily Raven is standing behind there wrong doing. Thank you guys once again for helping me through!
