The LV150 Series high level indicators provide a unique solution for tank overfill indication requiring self-checking. This indicator is designed with a 2" NPT mounting, making it ideal for use in underground and aboveground storage tanks. When mounted vertically at the tank top, it reliably indicates high liquid level.

To operate, simply press the brass tube fitting down to perform the self-check test. This manual operation physically moves the inner reed switch assembly while the float remains stationary (wet or dry). By doing this, the switch logic is inverted, checking the integrity of the circuitry without the need to remove the unit from the tank.

Adjustable versions are available for varying tank sizes. A special cinch nut on the mounting allows the stem to travel up or down to fine-tune actuation points. The extent of the adjustment depends on the unit’s length and distance from the mounting to the highest float stop.

The LV150 Series is offered in integral one foot lengths. For other lengths, adaptor systems are available. They consist of 2 parts: the LVR-C6S coupling (2 x 2" FNPT) and an LVR-6S pipe nipple (2 x 2" MNPT) of various lengths to change the insertion depth of the sensor. When using the adaptors, retaining clip pliers are required to remove the float for installation.
