Machine Category
The Machine Category identifies the type of machine for
the test. The Meter has a list of predefined categories:
Chillers (Refrigeration)
• Reciprocating (Open Motor and Compressor Separate)
• Reciprocating (Hermetic Motor and Compressor)
• Centrifugal (Hermetic or Open Motor)
Fans
• Belt-Driven Fans 1800 to 3600 RPM
• Belt-Driven Fans 600 to 1799 RPM
• General Direct Drive Fans (Direct Coupled)
• Vacuum Blowers (Belt or Direct Drive)
• Large Forced Draft Fans (Fluid Film Brgs.)
• Large Induced Draft Fans (Fluid Film Brgs.)

Centrifugal Pumps
• Vertical Pumps (Height: 12 ft to 20 ft / 3.7 m to 6 m)
• Vertical Pumps (Height: 8 ft to 12 ft / 2.4 m to 3.7 m)

• Vertical Pumps (Height: 0 ft to 5 ft / 0 m to 1.5 m)
Note
Height is measured from grade to top motor
bearing. It may be necessary to specify lower
alarm for the lower motor bearing and the upper
pump bearing (depending on height).
