4-66.2. TANK LEVEL INDICATION - TRANSMITTER - MAINTENANCE INSTRUCTIONS

GENERAL.

(1) The transmitter consists of a network of voltage divider resistors and magnetic reed switches which are

contained in silicon rubber potted in a mylar tube that is surrounded by a neoprene tube and all mounted in a

stainless steel tube. Electrical leads connecting to the resistors and magnetic reed switches are brought to

electrical connectors located at the bottom of the transmitter.

(2) A cylindrical float assembly located on the stainless steel tube is free to move up and down the tube

within limits established by pairs of brackets that are integral with the transmitters. The bracket pairs on the

tube are used as mounting surfaces for the installation of transmitters in the fluid tank.

(3) The transmitter is used in single-transmitter installation in which fluid levels at the top of the tank can

be indicated, but fluid levels can be indicated only to a minimum point that lies above the bottom of the tank.
