Mounting overview
Typically, the LectroCount LCR-II is mounted directly
onto a flow meter; however, some fixed installations
require the register be mounted away from the meter.
If the meter is equipped with an external POD pulser,
the LCR-II can be mounted up to 1000 wire feet (304
meters) away from the meter (actual distance depends
on pulser specifications and wire type).
Adapters are available for other PD meters such as
Neptune (PNs 81364, 82641, 82642), FMC Smith (PN
81370), and Brooks/Brodie (PN 81800) meters. Each kit
includes installation instructions.
Tips for mounting an lCr-II:
• Leave the cover assembly fastened to the base to protect
the internal components.
• Make sure the vertical drive shaft from the meter is
attached to the pulser drive shafts.
• Before securing the LCR-II to the meter or mounting
bracket, make sure the counter is visible and the keypad
and selector switch can be easily operated.
relieving Internal Pressure
All internal pressure must be relieved to zero pressure before disassembly or inspection of the strainer, vapor eliminator, any
valves in the system, the packing gland, and the front or rear covers.

6. Slowly crack the fitting on top of the differential valve to
relieve product pressure in the system. Product will drain
from the meter system.
7. As product is bleeding from the differential valve, slowly
reopen and close the valve/nozzle on the discharge line.
Repeat this step until the product stops draining from the
differential valve and discharge line valve/nozzle.
8. Leave the discharge line valve/nozzle open while working
on the system.
1. Close the belly valve of the supply tank.
2. Close the valve on the vapor return line.
3. Close the manual valve in the supply line on the inlet
side of the meter. If no manual valve exists on the inlet
side, consult the truck manufacturer for procedures to
depressurize the system.
4. Slowly open the valve/nozzle at the end of the supply
line.
5. After product has bled off, close the valve/nozzle at the
end of the supply line.
Serious injury or death from fire or explosion could result in performing maintenance on an
improperly depressurized and evacuated system.
