Gas bottle level detector with torch
This device is a portable filling level indicator for all (propane / butane - LPG) steel or aluminium gas cylinders with a diameter of 200 mm to 350 mm. It can be used to check whether there is liquid in the cylinder at the test point and determine the filling level. Simply hold the tip against the side of the gas cylinder and slide it downwards from the top until the gas indicator illuminates. Includes a push button torch function. Requires 1 x 9 V Battery to operate (included).
Hold the device, make sure the device is approximately horizontal in order that it is approximately perpendicular to the cylinder surface where you want to perform test. Then press the test head onto the cylinder surface. The device sounds a beep indicating that the contact between the test head and the gas cylinder is good. During the process, the red and green status indicator LED's flash instantaneously. When the device sounds a second beep the test finishes. The two status indicator LED's stop flashing and turn off, then immediately the red or green status indicator LED lights up to indicate the test result, as described as follows;
