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 100 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 Fluid Flow Meters are intrinsically safe for
Class I; Division 1; Group D hazardous indoor
(NEMA 1) locations when installed with an intrinsi-
cally 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.
Refer to Fig. 1 to locate and install the flow meter,
connectors, and fluid shutoff valves. Install a check
valve to prevent backflow. The arrows on the flow
meter and check valve show the direction of fluid
flow.
The shutoff valves allow you to isolate the meter for
service.
Refer to the Technical Data and Dimensional
Drawings for dimension, inlet/outlet size, tempera-
ture and other specifications.
