Gas bottle level indicator with integrated LED torch

Never run out of propane gas again with the Truma Gas Cylinder Level Checker with LED Light!

The device shows how much gas is left in the LPG cylinder and is child's play to use. The device is held horizontally against the gas cylinder and uses ultrasound to detect whether there is any liquid gas in the cylinder at the point where the measurement is being taken. The status LED turns green if there is gas at the measuring point and red if there is no gas, enabling you to find out how full the gas cylinder is quickly and easily. While the LED flashes orange whilst the device is determining the filling level; a beep indicates the beginning and end of the measurement.

The ultrasonic measurement makes it very precise and reliable and the LevelCheck is suitable for all propane, butane, steel or aluminium LPG gas cylinders with a diameter of 7.9 to 13.8 in (200 to 350 mm). This makes it a great help when camping or grilling over gas.

The practical LED torch that is integrated in the device offers extra added value. The LevelCheck has already won several awards in the caravanning sector as test winner and "best accessory".

The device is authorized for use in Australia.


How to Use the Truma Gas Bottle Gauge

In order to carry out a measurement, please:

  1. Place the LevelCheck against the wall of the gas cylinder horizontally and at an angle of 90° if possible. The filling level is determined using an ultrasound signal.
  2. If there is liquid gas within the measuring area, the signal is carried further and reflected by the opposite wall of the cylinder (echo). This measurement is indicated by a green LED and a high-pitched acoustic signal.
  3. If there is no gas at the measured point, the signal is not carried further and no echo occurs. This is indicated by a red LED and a lower-frequency acoustic signal.


NOTE: Measurements can be affected by the following: 

  • invisible rusty areas in the inside of the gas cylinder
  • an extremely thick coating of paint on the exterior of the gas cylinder
  • stickers on the outside of the gas cylinder
  • frozen condensation on the outside of the gas cylinder
  • dented or heavily scratched gas cylinders

  • Battery operated (9 volt battery is included)

Paul’s Tips

In order to obtain a reliable measurement:

  • Don’t take measurements in the lower area of full gas cylinder (because of the restricted reflection of the echo from the distant surface of the liquid gas)
  • Clean the measuring head regularly with a damp cloth (without a detergent)
  • Only measure for 1-2 seconds - any longer measurements 3 seconds and above will automatically show up red (empty) which may be incorrect
