Guard® DFG-250 - Digital Float “All in One” Level, Temperature, Pressure Gauge
Features & Benefits: The Digital Float Gauge can provide level, pressure, temperature, and alarms in a single 10” (250mm) penetration.
The local display on top of the unit is lighted and continuously scrolls through temperature and level (feet and inches or meters).
The unit is completely serviceable from the exterior of the unit and tanks. This feature prevents any exposure of cargo to the atmosphere.
The DFG is capable of measuring cargo tanks at a maximum of 20m (66ft). The DFG boasts a 5mm (1/4") level accuracy.
Display: Level (feet and inches) and temperature of cargo at three points is displayed on a SCU and the tank top. Data is sent to electronic enclosure and pressure, level, volume and temperature is displayed on either CMS+ software up to 19” touch screen in tankerman's shack and/or several explosion proof multi tank displays (MTDEs) located anywhere on deck.
