(1) HFS-2 Failsafe outputs : Relay NO/NC, 0/5/8v digital map switching – based on Level sensor(delayed) and On/Off switch

HFS-3 Failsafe outputs : Relay NO/NC, 0/5/8v digital map switching, .5-4.5V Analog output – based on flowsensor, level sensor(delayed) and On/Off switch

HFS-4 Failsafe outputs : Relay NO/NC, 0/5/8v digital map switching, .5-4.5V Analog output, Raw flowsensor pulse output – based on flowsensor, level sensor(delayed) and On/Off switch

(2) HFS-3 and 4 Flow Sensor mapping solder configurable by Howerton Engineering
