    摘要: measurement device for monitoring the level of liquefied gas in a canister is described. The device comprises an array of at least three temperature sensors, configured to be mounted externally of the canister to extend from a first position on the canister to a second position on the canister. The device also comprises detection circuitry for detecting, when gas is released from the canister causing a temperature drop at the liquid-gas interface within the canister, a subset of the temperature sensors measuring a lower temperature than the remainder of the temperature sensors, and for identifying a current level of the liquefied gas in the canister based on the position within the array of the subset of the temperature sensors detected as measuring a lower temperature. This arrangement can be retrofitted to any canister, without the need to modify the canister or change the valve arrangement.
