A gas cylinder monitoring device (34) for use with a valve (18) for controlling the flow of gas from a cylinder (14). The valve (18) has a valve body (20), and the device comprises an ambient temperature sensor (38) to measure the ambient temperature (TA), a valve body temperature sensor (36) to measure the temperature (TV) of the valve body, and a processor (42). The processor (42) operates to process a compensated temperature (CT) calculated from the difference between the measured valve body temperature (TV) and the ambient temperature (TA) over time (t). A flow-rate (FR) of the flow of gas from the cylinder and/or the pressure (P) on the gas is determined.
