Systems Monitors
Limitations and considerations for mounting the ultrasonic tank senders:
Vessel Systems Monitor Tank Sender - Gas Only
1811- 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 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.
