Gaslevel® classic, gas level indicator

Our expertise in the development and production of ultrasound-based level indicators enabled us to create our own product, too. Since 2010 we have offered a level indicator for propane gas cylinders called GASLEVEL®.

Just 6.5 cm high, 3 cm wide and 1.6 cm thick, the device is very practical and uses ultrasonic. Within seconds it measures the level of gas remaining in 5 kg, 11 kg and 33 kg propane gas cylinders. The GASLEVEL® Classic has a magnetic back, so you simply place it up against the gas cylinder and move it downwards until the indicator changes from red to green – when it reaches the area filled with liquid gas. The device even works with aluminum gas cylinders if it is pressed against the cylinder manually.

GASLEVEL® Classic is manufactured on modern product facilities in Iserlohn. The device meets EU Directive EMC 2004/108/EC and is approved for use in potentially explosive atmospheres (EX * II 3 G Ex nA IIA T3). This is especially important for commercial and industrial customers since it means they can use GASLEVEL® Classic in highly sensitive work areas.

Other areas of use

GASLEVEL® is ideal for measuring gas cylinder levels in the skilled craft trades (e.g. by roofers), in catering (e.g. for outdoor patio heaters), for private leisure (e.g. barbecues), on boats and in the camping sector (e.g. in caravans and motorhomes).

In order to measure the fill level of your butane or propane gas canister (5 kg, 11 kg or 33 kg), place the device against the upper section of the cylinder (it attaches itself by means of integrated magnets).

When the pressure switch is activated, a red indicator lamp lights up. Remove the device from the cylinder and replace it somewhat lower down. As soon as you reach the area filled with liquid gas, the indicator lamp changes from red to green. The fill level can be seen on the raised central line on the device, marked by two arrows. By moving the device gently up and down it is possible to identify the fill level very precisely.
