Have system with John blue pump, flow divider, 1psi check valve inline. No orifices or nozzles/tips. Brown box reports that pressure sensor is bad. Just bought planter and was wondering if it will even show psi with this system and I need to get a sensor or if the pressure is low enough that the sensor isn't needed. Fertilzer is working fine but wouldn't mind a sensor but $250 is a lot if it isn't needed. Looking for aftermarket pressure transducer that should work just the same.
