Blue Sea Systems 1811 Vessel System Monitor VSM 422 Gasoline Tank Level Sender

Blue Sea Systems Vessel System Monitor VSM 422 Gasoline Tank Level Sender
Ultrasonic technology used to measure the volume of liquid in gasoline tanks
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
Limitations and considerations for mounting the ultrasonic tank senders:
- Digital filtering - Eliminates errors due to liquids sloshing in mobile tanks
- Senders are calibrated to the VSM 422 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 24"
- Sender must be mounted perpendicular to the surface of the liquid
- The sender negative connection should be connected as directly as possible to the main negative bus.
