About

SeeLeveL Command

Features
Read full description

Garnet Instruments is a manufacturing company that specializes in fluid management systems. The SeeLeveL Command app allows users to configure and view data from 808-BTP3 Flair, 812 Octane, 806-C Vision, 806-Ci Vision, and 818 Input Module devices (commonly referred to as gauges) via Bluetooth Low Energy. These gauges connect to a measurement device (commonly referred to as a Bar) inside the tank of liquid transport trucks via a Fibre Optic Cable. Liquid transport tank data such as current level and volume, alarm set points, tank temperature, and tank pressure can be viewed within the SeeLeveL Command app. The Bar within a Liquid Transport tank has a length equal to the height of the tank. Each level increment along the length of the Bar has an associated volume. A set of level-volume pairings that cover the entirety of the measurement device’s length within the tank is referred to as a Calibration. Each device is shipped with a default calibration, however, because liquid transport tanks come in a variety of shapes and sizes, all gauges must be calibrated to ensure accuracy. The SeeLeveL Command app allows users to calibrate gauges via Bluetooth.
