Abstract: A method and system for measuring a weight of a deposit that forms on a tube bank independently-suspended by one or more hanger rods within a boiler are characterized by having one or more strain sensors and one or more load sensors, with each strain sensor being affixed to a separate hanger rod and each load sensor being coupled to a separate hanger rod. The strain sensors and load sensors are connected to a logic circuit for reading strain and/or load readings from the strain and/or load sensors and calculating the weight of the deposit as a function of the strain and/or load readings.
