System for monitoring amount of residual liquefied gas in gas cylinder

摘要: The invention provides a system for monitoring the amount of residual liquefied gas in cylinder and belongs to technical field special application indicating or metering devices. By adoption system, problem that prior art, cannot be monitored conveniently is solved. comprises body. temperature sensors which are arranged on body, wherein number at least two, sequentially evenly distributed spaced mode from top bottom. further acquisition circuit, data analysis processor mobile phone APP. A transmitter can transmit results APP also sensors, circuit connected sequence. According cylinder, collected through transmitted processor, worked out corresponding by transmitter, thus observation user facilitated.
