Fostering efficient installation for tankers with up to 5 compartments, Dataplus II M353 Series integrated Electronic Pump Metering System (EPMS) consolidates multiple pieces of equipment otherwise mounted around road tanker into one cabinet. All buttons are positioned within cabinet to facilitate use, and curved cabinet design negates damage from pipes accidentally drawn over front. If accidentally left open, door will close once vehicle starts moving and stay closed due to locking mechanism.
