This sensor is placed in the supply line of a water/methanol injection system to monitor actual fluid flow rate. Sensor outputs a square wave, 0-5v, variable frequency signal that can be easily monitored by most ECUs or data loggers. Allows proper monitoring of the actual amount of fluid injected while also providing a basis for a failsafe system based on flow. Can measure flow volume up to 1000cc/min. Sensor has 1/4” NPT male threads at each end. Sensor is available with flying lead or terminated with a 3P DTM connector.
