Environmental Compliance
Waste Electrical and Electronic Equipment (WEEE) Directive
Baker Hughes is an active participant in Europe’s Waste Electrical and Electronic Equipment (WEEE) take-back
initiative, directive 2002/96/EC.
The equipment that you bought has required the extraction and use of natural resources for its production. It may
contain hazardous substances that could impact health and the environment.
In order to avoid the dissemination of those substances in our environment and to diminish the pressure on the
natural resources, we encourage you to use the appropriate take-back systems. Those systems will reuse or recycle
most of the materials of your end life equipment in a sound way.
The crossed-out wheeled bin symbol invites you to use those systems.
If you need more information on the collection, reuse and recycling systems, please contact your local or regional
waste administration.
Visit www.bakerhughesds.com/health-safetyand-environment-hse for take-back instructions and more information
about this initiative.

1.1 Introduction
The 2-Channel Model DF868 flowmeter cannot provide accurate flow rate measurements for either channel until the
instrument has been properly installed, the channel has been activated, and the basic system and pipe parameters
have been programmed into the meter. See the Startup Guide for detailed instructions on performing these tasks.
After completing the installation, proceed with this chapter to program the Model DF868’s advanced features.
Four submenus within the User Program provide access to the various programmable features of the Model DF868.
Step-by-step programming instructions for each submenu are presented in this chapter. Refer to the appropriate
section for a discussion of the following User Program submenus:
•CH1/CH2 - use this submenu to activate a channel and to enter the basic setup parameters for that channel.
•GLOBL - use this submenu to enter global meter parameters (i.e., clock, system, input/output, communications
and security), which apply to both channels.
•SAVE - use this submenu to store both channel and global data in the meter’s memory, as a site file.
•RECLL - use this submenu to recall and activate a stored site file.
Note: It is not required that both channels of a 2-Channel Model DF868 be installed. The second channel
connector may simply be left vacant for future expansion.
As an aid in following the programming instructions, a complete menu map of the User Program is included in
Appendix A, Menu Maps.

1.6.1 Activating a Channel
The ACTIV submenu activates a channel and selects the desired measurement method.
1. To enter the Channel PROGRAM menu, press [F1] or [F2] (depending on the desired channel) at the User

The Model DF868 flowmeter can take measurements in two ways:
• The Correlation Transit-Time™ technique uses a pair of transducers (either wetted or clamp-on) with each
transducer alternately sending and receiving coded ultrasonic signals through the fluid. When the fluid is flowing,
signal transit time in the downstream direction is shorter than in the upstream direction; the difference between
these transit times is proportional to the flow velocity. The DF868 measures this very small time difference and,
using various digital signal processing techniques combined with programmed pipe parameters, determines
the flow rate and direction.
• The TransFlection® technique uses two transducers. One transducer shoots thousands of grouped ultrasonic
pulses in very rapid succession. The pulses bounce off “scatterers” in the liquid (bubbles, solids, or liquid droplets)
and are reflected back to the other transducer. Each received pulse group receives a “snapshot” of the flow. By
comparing all snapshots and averaging out objects that do not appear to move with the flow, the DF868 can
determine flow rate and direction.
Note: If the DF868 has not been ordered with TransFlection mode, the TRNFL option does not appear.
