Characteristics of On-Wall In-Tube Flexible Thermal Flow Sensor at Wrap Pipe Condition

We previously proposed a novel type of on-wall in-tube thermal flexible sensor, and confirmed that it can measure the flow-rate in both hydraulically developing and fully-developed conditions. This time, we investigated another outstanding advantage, i.e. the sensor is able to measure the flow-rate at axially asymmetric flow condition, and found that the sensor is applicable for the measurement of the flow-rate in bent tube condition.
