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 intrinsically safe power device and wiring.
Refer to ANSI standards
•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 Dimensions Drawings for dimension, inlet/outlet size, tempera- ture and other specifications.
