Connecting Sender Unit  (refer diagram below)

​

• The sender unit must be installed in the horizontal position

• The thread specification of the sender unit is 3/8" Barb 

• Make sure the sender is fitted with the fuel flow in the direction of the arrow noting that

      flow direction is one way

• Connect directly with a 3/8" hose, noting that hose clamps should always be used to secure the connection

• The display comes pre-wired with an approximately 1.4m sender cable  

• Extra 1.4m & 3m extension leads are available for the three pin plugs

• Up to 6 leads may be joined to make 9.8m in total length

• Please Note:  Sender leads cannot be cut and joined – this will void your warranty, extension leads must be  used

 

​

​Connection to 12Volt DC Adapter

 

• It is recommended that you get the 12v power from the pump circuit

• Simply cut off the two pin 12v plug to the required length and connect the black wire to the negative terminal and the red wire to the positive power source

• The back-light will stay ON when connected to 12v

• All settings and amounts will be stored if power is disconnected
   

 

Current use at 12Volt DC Adapter

​

• 1 mA when operational

• 0.015 mA when asleep 

• Please Note: 1,000 mA (milliamp) = 1 A (amp)

​

Programming & Display Selection

​

• Press "DISPLAY" button to turn display on the screen

• To set the Display for the 3/8" sender supplied you will need to press both buttons at the same time & release.  "H34" is the setting that you need displayed

• If "H34" is not displayed, continue to press and release the "DISPLAY" button until "H34" is displayed

• Press "DISPLAY" button again, this will display the accumulated flowing volume (flow totalisation) or real time flow rate

• Press and release "RESET" button for four seconds which will reset the total measuring volume to zero

• Please Note:  The maximum monitoring capacity is 99,999 litres

​

​

Operating

​

• The Topargee H2F-FCU38RM Micro Fuel Flow Meter will automatically turn on when there is fuel flowing through the sensor
