Key Features & Benefits
Model 808-P2
The SeeLeveL Special™ 808-P2 is a high-accuracy liquid volume monitoring system designed for tank trucks carrying flammable liquids. Its all-digital technology eliminates reading drift and uses fiber optic communication to avoid the risk of arcing or sparking where intrinsic safety is critical. The SeeLeveL Special™ connects to the sender using fiber optic technology to help prevent the risk of sparking in safety-critical environments. The fiber optic cable can be cut and terminated without special tools or equipment, making installation simple and efficient.
