Frequently Asked Questions

What is the F22 Message?


The “F22” will display sometimes.

This is not a fault. It is the code for the different senders.

If this setting has been accidentally changed it can be easily reset by pressing both buttons at the same time and scrolling through until it shows “F22” again.

Pressing both buttons will also reset the amount to the programmed amount.




Screen turns on but amount does not change


Check that the snake at the top of the screen is moving when water flows. If it is moving this is a normal condition. Check if the water is flowing in the direction of the arrow on the sender. If it is not flowing in the direction of the arrow, refit sender in direction of flow. Check that nothing is caught in the implellar, such as teflon tape. It could be something as little as shavings from holes drilled in the tank at some stage. Make sure you remove debris carefully. Have the sender wires been cut and joined? If they have this would cause this issue and your warranty is void If you have fitted extension leads, unplug them, then remove sender and plug into 1.4mt lead from display and blow into lightly to check. Press both buttons at the same time and release - H22 should be displayed. If “H22” is not displayed, keep pressing and releasing the "DISPLAY" button until “H22” is displayed. Wait until the screen turns off and the unit will store the setting. This is the correct code for the ½" sender supplied with these models. Screen turns on and snake at top of screen moves but amount does not change. Refer above. Check if litre is displayed in the bottom right hand corner. If displaying in gallons please refer to FAQ - Changing from litres to gallons or gallons to litres?




Display is reading out by a large amount eg 1 litre for every 3-5 litres


If your display is out by a large amount it is usually because you have managed to change the sender codes Press both buttons at the same time and release - H22 should be displayed. If “H22” is not displayed, keep pressing and releasing the "DISPLAY" button until “H22” is displayed. Wait until the screen turns off and the unit will memorise the setting. This is the correct code for the ½’ sender supplied with these models. Also ensure the display is not reading in gallons instead of litres. If this is the case refer to FAQ - Changing from litres to gallons or gallons to litres.




Changing from litres to gallons or gallons to litres


There is a small LTR or GAL next to the amount displayed to show which mode you are in Disconnect the power (or batteries) Press and hold the “PROG” button while reconnecting the power Release the button after you hear the long beep. The display will be switched (from LTR to GAL, or GAL to LTR) Wait until the screen turns off and the unit will memorise the setting




Screen stays on or locks up and will not respond to any buttons


In the unlikely event that this happens, disconnect power. Press the "DISPLAY" button to release any holdover charge in the capacitors. Wait 30 seconds and reconnect power. Display will reboot and go through self check and restart.




Why isn't my water use being recorded?


Ensure you do not turn the display "POWER OFF" until it has gone to sleep - this takes approx 10 seconds. The remaining quantity is only recorded in memory after the display has gone to sleep.​




Why can't I fit the sender before the pump?


If you have no room after the pump, the sender can be fitted before the pump. The main reason we don't recommend this is if you do not tighten all connectors properly and there is a tiny pin hole, air will enter the hose line and the water will drain back into the tank. If the sender is fitted on the pressure side any leaks become obvious. However, if fitted correctly the sender can be fitted either side of the pump.




No Display?


For AA battery models, check that the batteries are fitted the right way and are fresh/charged. Remove and replace correctly. For 12V Models, ensure the cables are not connected in reverse. Connect red wire to positive and black to negative.




Screen flashes on when no water is being used


This can sometimes happen for the following reasons:

  1. If the magnet in the sender stops next to the Hall Effect sensor inside the sender unit and there is any slight movement in the RV. If this is the case, the simple solution is to open and close a tap quickly to move the impeller to a different position.
  2. Turn the pump off if the 12v power for the display is coming from the same circuit (this is the recommended power source for the H2F-FM 12v model).
  3. If the water pipe does not have any water in it, however the impeller is free to turn in air this could cause this issue. The reason this sometimes happen is if the sender is fitted to the inlet side (suction side) of the pump. In this case turn the display power off. All settings and quantity will be stored.
  4. If the sender is fitted to the suction side of pump and there is a slight drop in pressure caused by an old pump (unable to hold prime), air getting into line or severe corrugations could all cause the unit to flash on. This is another reason we recommend the sender be fitted to the pressure side of pump.




Screen turns red (H2F-FM Flush Mount Water Tank Gauge)


This will happen if the battery voltage drops below 9v. When quantity reaches 000 or -001 the display will turn red and the buzzer will sound.




Cannot find eFlow Meter or the App is Hanging  (H2F-BT12 Bluetooth Water Tank Gauge)


Go to Setting > Google > Location > Choose OFF
Quit from Setting > Quit from eFlow and enter it again
eFlow will ask you location permission > choose YES




​​eFlow shuts down (H2F-BT12 Bluetooth Water Tank Gauge)


Go to Setting > Apps > eFlow > Storage
Choose CLEAR DATA & CLEAR CACHE
Quit from Setting > Quit from eFlow and enter it again




The H2F-BT12 Bluetooth Water Tank Gauge won't work with my Android Phone


The H2F-BT12 Bluetooth Water Tank Gauge is only compatable with Android 8 or later.




Generally how long will the batteries last in the Water Tank Gauges (HF-SM & HF-BT12)


On average the batteries last approx 2 years with normal use with the HF-SM Surface Mount Water Tank Gauge and approx 12 months with the HF-BT12 Bluetooth Water Tank Gauge Model.




How many extension leads can I use?


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




Can I cut the sender leads?


Sender leads cannot be cut and joined – this will void your warranty. Extension leads must be used.




How Many litres will the Water Gauge read?


The maximum monitoring capacity is 99,999 litres.




If I have multiple tanks does the gauge read seperately or does it read the combined amount?


Using the example of having 3 x 100 litre tanks - the gauges can read either way depending on the way you set it up.

You can set the gauge up to read one tank at a time, ie 1 x 100 litres, then when that tank is empty you can set it up to read the next water tank and so on.

Alternatively, you can set it up to read the whole combined amount of the three tanks totalling 300 litres.




What is new about the H2-FM Flush Mount Water Tank Gauge?


The FM Flush Mount replaced the RM model approx 6 years ago. It is 12v only, has a larger backlit screen and must be fitted at eye height or above as polarised, therefore you can read it in bright daylight. Please refer to the Product for full list of Specifications.




Can a sender unit be fitted to the incoming water tank to measure the amount of water you put into the tank?


Put simply this cannot be done.




Can I use a 24v system with the H2-FM Flush Mount Water Tank Gauge?


Yes you would just need to get a 24-12v Transformer/Convertor.




My tank fills and empties from the same water line. Will the gauge count backwards when the tank is being filled and the water flowing in the opposite direction?


The gauge only reads one way and therefore will not register when you are filling the tank. Once the tank is filled press the reset button and it will change back to your pre-programmed amount. Please note the sender unit is fitted after the pump.




Will there be any restrictions in the water tank gauges in flow or reduce outlet water pressure if for example I run a 50 litre water tank in a canopy that is gravity fed only?


The minimum flow is 1.5 LPM. To test it you will need to have the tank nearly empty then time it with a 2 litre milk bottle. If it is over 1.5 LPM then you will have no problems.




Will the H2F-FM Flush Mount Water Tank Gauge work with a hand pump style tap that is standard in the Jayco Camper Trailers?


The H2F-FM Flush Mount Water Tank Gauge will work with a hand pump. We are aware that a lot of the FM water gauges are fitted in the Jayco Camper Trailers. Please note the minimum flow is 1.5 LPM.




Can more than one sender be used with the gauges?


No only 1 sender can be used.




What are the dimensions of the H2F-FM Flush Mount Water Tank Gauge?


87mm (w) x 30 mm (d) x 80 mm (h) - please refer diagram below




What are the dimensions of the H2F-SM Surface Mount Water Tank Gauge?


71.5 mm (w) x 56 mm (h) - please refer to diagram below.




What are the dimensions of the H2F-BT12 Bluetooth Water Tank Gauge?


69 mm (w) x 40 mm (d) x 70 mm (h)




Is there a way to add a specific amount of water eg 20 litres rather than always needing to fill the tank and reset gauge to full?


When designing our gauges we wanted to keep the operation as simple as possible. You can always set your volume on the gauge to any amount without just resetting it to full. For example if you have a 200 litre tank and it goes down to 150 litres and you add the extra 20 litres, change your tank size in the device to 170 litres and off you go with your 170 litres of water. Then when you refill and you top the tank, reset the gauge volume to 200 again.




What do I do if I get a blank blue screen on my H2F-FM Flush Mount Water Tank Gauge?


The blue screen is generally caused by the power being too high.

When the power gets over 12v it can cause the screen to not work.

We would recommend checking you power levels and this should fix this issues.
