Blue Sea Tank meter

Accurate - used with the Vessel Systems Monitor VSM 422 PN 1800 - can be precisely calibrated for each tank*
Reliable - SSI Technologies, Inc. Fluid-Trac? is non-contacting eliminating any mechanical moving parts that can wear and cause intermittent or complete signal loss
Digital filtering - Eliminates errors due to liquids sloshing in mobile tanks

Limitations and considerations for mounting the ultrasonic tank senders:
Senders are calibrated to the VSM 422 and M2 Meters and will not function with other monitors
Senders must be mounted 4 or greater distance from a tank side or baffle
Tank floor must not be sloped
Tanks must not be deeper than 32
Sender must be mounted perpendicular to the surface of the liquid
The sender negative connection should be connect
