ABSTRACT:
A liquid type identifying method and device for correctly and quickly determining whether or not a liquid is a predetermined one. An identifying sensor unit (2) so disposed as to face a flow passage (24) of a liquid to be measured has an indirect-heating liquid type detecting section (21) including a heater and a heat sensor and a liquid temperature sensing section (22). A single pulse voltage is applied to the heater of the liquid type detecting section to allow the heater to generate heat, and an identification calculation section makes an identification according to the output of the liquid type detecting circuit including the heat sensor of the liquid type detecting section and the liquid temperature sensing section.
