Introduction
1. Continuous Float Transmitters should be installed rigidly so the float is free to move as
the liquid level changes.
2. Continuous Float Transmitters should be mounted in a tank area free of severe turbulence
or protected from such turbulence by appropriate and adequate slosh shields.
3. Continuous Float Transmitters stems should be vertical for best results, but satisfactory
operation is possible in most liquids with the stem at up to a 30° angle from vertical.
4. Care should be taken that Continuous Float Transmitters are always operated within
electrical ratings.
Technology
Flowline’s continuous float transmitter is designed for vertical mounting in a tank. Reed
switches are evenly spaced over the operation range to achieve the desired resolution. A single
magnet-containing float travels the length of the sensing range. The reed switches are
magnetically actuated as the float moves with the liquid level. DC power is applied to the
switch, and the output signal can then be routed to programmable controllers, microprocessors or
other readout devices.
