Mechanical Line Leak Detector <br /> For use with 4"STPs,the MLD product line is precision built,with unique construction •All models are capable of detecting <br /> features that provide busy stations with maximum flow rates and long service life.The MLD line leaks equivalent to 3 gph at <br /> is offered in three models to match your exact application,ensuring accurate,nuisance-free 10 psi when installed properly with <br /> operation critical to profitable station operation. the appropriate fuels.All models will <br /> signal detection of leaks by <br /> restricting product delivery to less <br /> than 3 gpm and taking more than <br /> 4 seconds to open. <br /> •All models require 2 to 3 seconds to <br /> make a line test when no line leaks <br /> BURNISHED BRASS exist and air is purged from piping <br /> CYLINDER LINER between the discharge of the MLD <br /> BRASS PISTON TEFLON SEAL and the dispenser solenoid. <br /> THERMAL CONTRACTION �I •All models will remain in the"open" <br /> COMPENSATION CHAMBER position during product delivery to <br /> TEFLON SEAL manifold,with discharge pressures as <br /> low as I psi.All models will reset to <br /> _ the"tripped"when line pressure <br /> .t•> delay is below 3 psi with pump off. <br /> •All models will detect leaks up to 10 <br /> feet above the MLD installation point. <br /> GROUND AND <br /> POLISHED <br /> STAINLESS STEEL C UL US LISTED <br /> PISTON ROD <br /> i. <br /> r. <br /> Specifications: Approvals <br /> •Three models:STP-MLD(blue)for gasoline, •Third party certified to comply with US EPA <br /> STP-MLD-D(tan)for diesel and STP-MLD-E requirements 280.41 (B)and 280.44(A)for <br /> (grey)for some expandable pipe continuous monitoring of pressurized piping. <br /> applications. •Consult factory for other <br /> •Solid brass piston has 1-5/8"of travel to applicable approvals. <br /> move the leak detection poppet fully out of <br /> the flow,offering minimum flow restriction Quality Certification <br /> and maximum flow rates. •Franklin Fueling Systems is an ISO 9001 <br /> •Burnished brass cylinder liner and polished Certified Manufacturer. <br /> stainless steel piston rod ensure smooth <br /> operation and long life from the Teflon seal. <br /> •Thermal compensation chamber of <br /> 5-3/4 cubic inches helps minimize thermal <br /> contraction nuisance tripping. <br /> Liquid Compatibility <br /> •Max.liquid viscosity:70 SSU at 60 OF(15°C). <br /> •STP-MLD and STP-MLD-E models are <br /> compatible with fuel mixtures containing <br /> up to 100%ethanol or methanol,and <br /> 20%MTBE,20%ETRE or 17%TAME <br /> with gasoline,as well as diesel fuels,fuel <br /> oils,kerosene,Avgas and jet fuels. <br /> •STP-MLD-D models are listed for diesel <br /> fuels or kerosene only. <br /> 24 <br />
