1. A method of improving a bimetallic pipe thermometer utilizing a tubular seat with an open-ended tail slot that extends longitudinally along a sidewall of the tubular seat, wherein the bimetallic pipe thermometer comprises a bimetallic coil sensor configured to convert temperature change to vertical mechanical displacement of a tail of the bimetallic coil sensor, the method comprising:
calibrating the bimetallic coil sensor by confining said tail in said open-ended tail slot until it is finally calibrated; and
closing off a proximal end of the open-ended tail slot with a stop.
