Correct answer is (b) Weight

Best explanation: Weight sensors are used to measure the change in flow rate. Along with weight sensors the flow rate sensors are also used to measure the change in flow rate. Temperature is used to measure the hotness or coldness of the medium. Whereas the medium and exit-gas analyzers are used to measure the change in feed rate.
