Manual

The COX Series 4000 Flow Computer is an integral
part of a complete system from Cox which provides
the most accurate flow metering capabilities in the
industry. Its state-of-the-art electronics automatically
compensate for nonlinearity caused by high fluid
viscosity, and nonlinearity inherent with LO FLO
meters, thus maintaining the calibrated accuracy of
the turbine meters over their entire flow ranges.
Key features for both Models 4010 and 4020:
• Linearization
Program up to 40 calibration points via front
panel keypad, RS-485 port, or COX QuickLoad
Software
• Compensates for inherent nonlinearity caused by:
- Higher viscosity fluids such as hydraulic oils,
diesel fuel, automotive oils
- Lo Flo Series characteristic nonlinearity
• Flow totalization, local and remote
• RS-485 communications port
Useful for changing calibration data in the field
and interfacing with a central PC
• Direct indication in standard engineering
units: GPM, PPM, LPM, etc.
Options for both Models 4010 and 4020:
• NEMA 4 housing for wall mount applications
• Explosion-proof housings
- Class I, Division I, Groups C and D
- Class I, Division I, Groups E, F, and G
• RS-232 serial communications port in separate
enclosure
• QuickLoad Software
(c/w RS485
➯ RS232 Converter)
In addition to all of the key features listed,
the Model 4020 Flow Computer also provides:
• Temperature compensation
Using an RTD temperature input and viscosity vs.
temperature data fluctuations in viscosity and
specific gravity caused by fluid temperature
variations can be automatically corrected
• Data acquisition system interface
Optically isolated 4-20 mA DC analog output,
linearly proportion to flow rate, for connection to
chart recorders or other instrumentation
