This data sheet can be used to test the mechanical line leak detector (MLLD) and electronic line leak detector (ELLD) with submersible turbine
pump (STP) systems. See PEI/RP 1200 Sections 9.1 and 9.2 for test procedures.

MLLD (ALL PRESSURE MEASURMENTS ARE MADE IN PSIG)
STP full operating pressure 28 28 28
Check valve holding pressure 19 19 19
Line resiliency (ml) (line bleedback volume as measured
from check valve holding pressure to 0 psig) 105 105 105
Step through time in seconds (time the MLLD hesitates at
metering pressure before going to full operating pressure as
measured from 0 sig with no leak induced on the line)
3 3 3
Metering pressure (STP pressure when simulated leak rate 3
gph at 10 psig) 15 15 15
Opening time in seconds (the time the MLLD opens to allow
full pressure after simulated leak is stopped) 3 3 3
Does the STP pressure remain at or below the metering
pressure for at least 60 seconds when the simulated leak is
induced? ☒Yes ☐No ☒Yes ☐No ☒Yes ☐No ☐Yes ☐No
Does the leak detector reset (trip) when the line pressure is
bled off to zero psig? ☒Yes ☐No ☒Yes ☐No ☒Yes ☐No ☐Yes ☐No
Does STP properly clycle on/off under normal fuel system
operating conditions? ☒Yes ☐No ☒Yes ☐No ☒Yes ☐No ☐Yes ☐No
A "No" answer to any of the above questions indicates that the MLLD fails the test.
ELLD (ALL PRESSURE MEASURMENTS ARE MADE IN PSIG)
STP full operating pressure
How many test cycles are observed before alarm/shutdown
occurs?
Does the simulated leak cause on alarm? ☐Yes ☐No ☐Yes ☐No ☐Yes ☐No ☐Yes ☐No
A "No" answer to the above question indicates that the ELLD fails the test.
Does the simulated leak cause an STP shutdown? ☐Yes ☐No ☐Yes ☐No ☐Yes ☐No ☐Yes ☐No
Test Results ☒Pass ☐Fail ☒Pass ☐Fail ☒Pass ☐Fail ☐Pass ☐Fail
