1) Can be caused by a gas pocket
that displaces the liquid.
2) The sensor is sealed with (too
much) Teflon tape so that there
is no metallic contact between
the sensor mechanism and the
vessel.
Threaded sleeves are installed
with a negative slope so that
liquid can collect in the threaded
sleeves, which activates the
sensor.
1) Install the sensor so that the
gas pockets cannot displace the
liquid
2) Make sure that the sensor has
a metallic connection to the
container.
Place the threaded sleeves
according to the instructions. See
