Adaptable Suppression Tank Level Sensor

A method for remanufacturing a fire suppressant storage device (20) from a first configuration to a second configuration, the fire suppressant storage device having in the first condition:

• a tank (22) having a first port(40), a second port (70), and an interior (32) for storing fire suppressant;
• a discharge assembly (46) mounted to the first port and comprising:
• a discharge valve (48);
• and
• a discharge conduit (50) at least partially within the interior and having:
• an interior;
• and
• an exterior;
• and
• a liquid level measurement assembly mounted to the second port and comprising:
• a tube (100) at least partially within the interior and having:
• an interior sealed relative to the surrounding tank interior;
• and
• an exterior;
• a float (120) surrounding the tube;
• and
• a magnetic member (122) axially moveable within the tube interior,
• the method comprising:
• removing the magnetic member;
• inserting into the tube a carrier (150) bearing a plurality of magnetic field sensors (152, 154), the carrier extending from a proximal end (156) to a distal end (158) and electronically coupling the plurality of magnetic field sensors to an electronics module (166), during the inserting one or more of the magnetic field sensors passing through the float;
• and
• using said passing to calibrate the electronics module.
