PURPOSE:To detect a liquid level easily without working a high pressure container at all and to know the amount of liquefied gas by measuring the temperature of the high pressure gas container at two points and detecting the liquid level between both measurement points from the temperature difference between both measurement points. CONSTITUTION:Temperature sensors 1, preferably, two electronic temperature sensors which take remote measurements are attached to the lower part of the high pressure gas container 2 at a proper vertical interval detachably, preferably, by magnets, suction rubber pressing type adhesives, etc.; if some temperature difference is generated between both measurement points, a comparator 3 generates a signal to turn on an alarm lamp or buzzer. The temperature sensors are moved to detect the current liquid level. |
