The Automatic water ballast meter is designed to make water filling simple. No more guesswork about how much water is in your wings! No more wasted water spilling out because you forgot to turn the hose or pump off when the wings were full! Using the Watermeter is really simple. Just connect to mains or water pump, set the number of litres you want to fill and press start. You will get an accurately metered dose of water, and then the water meter closes the valve and stops the pump automatically when you reach the water level you need, leaving you to spend time on other glider preparation.

Our Sets are coming with a wing holder!!!

Set WMS_V - Hose outlet from water mains

This set is dedicated for feeding water from water mains. The water is fed from a feeder hose (not included in the package) to the Watermeter. You can take the unit with you near to the filling point and the 4 meters long filling hose in this set is enough to reach any filling hole. The 12 meters long feeder cable provides you a good working range so you can easily leave your car behind the glider while the filling is ongoing. In case you don’t need such a long hose simply cut it down to any length. The set contains:

  • Watermeter
  • Wing holder
  • Feeder-cable 12m
  • Hose 4m
  • Hose connector with Control valve
  • Hose connector
  • 2pcs Tap connector ½"


Set WMS_C - Hose outlet with submersible pump

This set is intended to be choice of all the people who are using barrels rather than water mains. The barrels are supposed to be placed in the car or somewhere near by so 4 meter long feeder cable is provided. Part of the delivery is powerful submersible water pump with all the relevant attachements so the only thing you need to do is to plug the connector in the Watermeter and put the pump in the barrel. For a good reach a 12 meters long filling hose is provided. The set contains:

  • Watermeter
  • Wing holder
  • Feeder-cable 4m
  • Water pump with hose and cable
  • Hose 12m
  • 2pcs Hose connector
  • 2pcs Tap connector ½"


Wing holder

The wing holder sticks the Watermeter on a glossy surface with four small suction-cups. It is ideal for gliders with filling holes on the top of the wing but it is really convenient for all the other situations where the Watermeter is placed near by the glider.
