Badger Meter High Temperature Fluid Meter - Manual (Page 8)

INSTALLATION
THIS PRODUCT SHOULD BE INSTALLED AND SERVICED BY TECHNICALLY QUALIFIED PERSONNEL TRAINED IN
MAINTAINING INDUSTRIAL CLASS FLOW INSTRUMENTATION AND PROCESSING EQUIPMENT.
READ INSTRUCTIONS THOROUGHLY BEFORE INSTALLING THE UNIT. IF YOU HAVE ANY QUESTIONS REGARDING
PRODUCT INSTALLATION OR MAINTENANCE, CALL YOUR LOCAL SUPPLIER FOR MORE INFORMATION.
OIL METERS ARE NOT RECOMMENDED FOR WATER MONITORING APPLICATIONS. IF METER IS TO BE SUBJECTED TO
BOTH OIL AND WATER, WATER METERS (BRASS) ARE SUGGESTED. CONSULT FACTORY FOR DETAILS.
THIS METER MAY CONTAIN RESIDUAL AMOUNTS OF TEST FLUID AT THE TIME OF SHIPMENT. THIS FLUID SHOULD BE
REMOVED PRIOR TO INSTALLATION AS THE FLUID MAY BE INCOMPATIBLE OR HAZARDOUS WITH SOME LIQUIDS OR
GASES. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN DAMAGE TO THE EQUIPMENT.
THIS STANDARD METER IS UNIDIRECTIONAL. ATTEMPTS TO FLOW FLUIDS IN THE OPPOSITE DIRECTION OF THE FLOW
ARROW WILL RESULT IN THE METER ACTING AS A CHECK VALVE, CREATING A DEADHEADING SITUATION. IF THE
DIFFERENTIAL PRESSURE MAGNITUDE IS GREAT ENOUGH, DAMAGE TO THE INTERNAL PARTS OF THE METER WILL
RESULT.
The inline flow meter is a simple device to install . However, the following measures are recommended for reliable, trouble-
free operation:
• Align pipe accurately . Piping should be accurately aligned and of correct length . The high pressure body of the flow meter
can withstand shock and flow/pressure pulsation . However, the piping should be firmly supported by external mounting
brackets, both upstream and downstream of the meter, to avoid any pipe flexing actions that could reduce meter life .
• Use rigid mounting . If the flow meter inlet or outlet are to be rigidly mounted, and the opposing port is to be connected to
flexible hose, the end connected with the flexible hose must be rigidly mounted .
• Use Teflon® tape for sealing NPT fitting .
• Install unions . Install a union near the inlet or outlet of the meter . This will facilitate quick, easy meter removal and
inspection during periodic maintenance procedures .
• Mount the meter either horizontally or vertically (flow arrow pointing to either side or straight up) . If the meter must be
mounted inverted, special inverted scales are available from the factory .
• Ensure the fluid is traveling in the direction of the flow arrow (Figure 1) .
• Use at least a 200 mesh (74 micron) filter . The meter will allow particulate to pass that would jam most valves and flow
controls . Systems that do not have filtration should be equipped with at least a 200 mesh (74 micron) filter . Most hydraulic
systems already have much finer filtration .
• Dirt, ferrous metal or sealing agents, such as Teflon® tape may lodge and cause malfunction . If the meter is jammed at a
fixed position, follow cleaning and maintenance instructions .
• Do not use thread locking compounds as thread sealant .
