Installation
WARNING
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
To reduce the risk of fire, explosion, or
electric shock:
All electrical equipment must only be installed
by a qualified electrician.
Understand and follow your local code and
safety regulations for hazardous location wiring
of intrinsically safe circuits.
Dust and Foreign Matter
Avoid having dust or foreign matter enter the flow
meter by taking the following precautions:
Thoroughly flush the fluid supply lines before
installing the flow meter.
When installing fittings, make sure that no sealing
tape overlaps into the inside of the pipe.
Install a 200 mesh fluid filter upstream of the flow
meter.
Installing the Flow Meter
Flow volume can only be measured at the location
where the flow meter is installed.
The meter is intrinsically safe for Class I; Division
1; Group D hazardous indoor (NEMA 1) locations
when installed with an intrinsically safe power
device and wiring.
Refer to ANSI standards ISA-RP12.6, NEC Article
504 and the Canadian Electrical Code Appendix F.
Do not use more than 200 ft. (61 m) of cable.
Grounding
WARNING
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
Proper electrical grounding of your
system is essential. For your safety,
read the warning section, FIRE, EXPLO-
SION, AND ELECTRIC SHOCK HAZARD, on
page 3.
1. Ground the flow meter by connecting a grounded
cable to the sensor. Part No. 116005 Cable is
available (must be ordered separately).
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 resist-
ance from the cable connector Pin A to true earth
ground. Refer to the Wiring Diagram on page 7.
If the resistance is greater than 25 ohms, check
the cable ground connection. Reconnect the
ground sheath or replace the cable. Do not oper-
ate the system until the problem is corrected.
2. Always ground the fluid supply unit, using one of
the following options:
a. Mount the meter to a grounded conductive
surface, or
b. Connect the conductive fluid hose to the meter
inlet and outlet, or
c. Connect a ground wire to the meter’s 1/4–20
unc mounting holes.
3. Never use the flow meter with an electrostatic gun
isolation stand.
