A cylindrical thermistor can potentially be used to build a fuel flow meter, but specific application details are crucial for effective implementation. Clarification is needed on whether a hollow or solid cylinder is intended for the design. The sensitivity of the thermistor is a concern, as it may struggle to detect fuel flow unless the fuel is significantly heated. Further discussion on the application context and requirements would enhance the feasibility assessment. Overall, careful consideration of thermistor specifications and design parameters is essential for successful integration.
