10 LED Dual Water / Foam
The SL System has been the standard in level indication in the fire industry for 15 years. The display modules feature 3 dimensional lenses for 180-degree visibility. All display module electronics are encapsulated in potting compound to protect the unit from shock, vibration, water, and dust.
The easy to install sending unit is constructed of stainless steel and features a vent to atmosphere which prevents inaccuracy typically associated with altitude changes. The sender unit remains in all types of water and foam.
All display modules are self-calibrating for three common tank styles (rectangular, elliptical, and T-Shaped).
