Grounding
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.
1. Ground the flow meter by connecting a grounded
cable to the meter housing or sensor.
Have a qualified electrician check the electrical
grounding continuity between the flow meter sensor
and a true earth ground; remove the cable
connector from the sensor and measure the
resistance from the cable connector Pin 2 to true
earth ground. Refer to F
If the resistance is greater than 25 ohms, check the
cable ground connection. Refer to F
Reconnect the ground sheath or replace the cable.
Do not operate the system until the problem is
corrected.
Meter Cables and Adaptor
See Table 1: for available meter cables or the adaptor for use with cables with a black plastic connector and a
replacement sensor.

NOTE: These cables have a metal connector, which will only mate with a sensor that also
has a metal connector. Adaptor 24Y434 (purchased separately) is required to connect an
existing cable with a plastic connector to a replacement sensor, which has a metal
connector.

2. Always ground the meter, using one of the following
options:
a. Mount the meter to a grounded conductive
surface, or
b. Connect the conductive fluid line to the meter
inlet and outlet, or
c. Connect a ground wire to the meter's M6
mounting holes.
