  • Page 6: Operating Theory

    OPERATING THEORY The FUSION ultrasonic flow meter is designed to measure volu- metric flow of clean, solids-bearing or aerated liquid on full pipes. There are no moving parts to jam or wear and the product can- not be damaged by gas pockets, particulate or high flowing con- ditions.

    Pressure 300 PSI [2,070 kPa] Temperature -30 to +160 F [-34 to +70 C] Outputs (FUSION cannot output 4-20mA and Rate Pulse simul- taneously. Only one can be selected.) 4-20mA 12-bit; source from DC supply voltage Rate Pulse 0-1,000 Hz; open collector; internal/ external pull-up;...
  • Page 8 Do not connect or disconnect either power or outputs unless the area is known to be non- hazardous. IMPORTANT NOTE: Do not connect the interface cable between a FUSION flow meter and a personal computer unless the area is known to be non-hazardous.

  • Page 9: Mounting Location

    1. MOUNTING LOCATION The first step in the installation process is the selection of an optimum location for the flow measurement to be made. For this to be done effectively, a basic knowledge of the piping system and its plumbing is required. The pipe must be completely filled with liquid while measurements are being made—avoid installations where pipes can become par- tially filled for long periods of time.

    2. PLUMBING FUSION is equipped with an IN directional arrow pointing in the flow direction that will produce positive readings with the FLO DIR set to POS. Mount the meter for best viewing of the display re- gardless of the flow direction; the direction can be changed in CONFIGURATION (see page 23).
  • Page 11 Figure 4. The optimum straight pipe diameter recommendations apply to pipes in both horizontal and vertical orientation. Note: If adequate straight plumbing cannot be provided the FUSION will operate repeatably and reliably, but will not achieve optimum accuracy. Outdoor Installations...

    3. ELECTRICAL CONNECTIONS The FUSION flow meter is equipped with three threaded conduit holes located on the bottom of the flow meter enclosure that are suitable for routing of field wiring. A sealed cord grip or sealed threaded conduit connection should be utilized to retain the NEMA 4 integrity of the flow meter enclosure.

  • Page 14 4-20mA CONNECTION The FUSION is equipped with a ground-referenced 4-20 mA output—the output shares a common ground with the power supply. The output transmits a continuous current output that is proportional to liquid flow rate. The output was scaled at the Dynasonics factory and the scaling information is recorded on the label located outside of the FUSION enclosure.
  • Page 15 The maximum resistance that the FUSION can accommodate is directly related to the DC power source that is powering the flow meter and the 4-20 mA loop.
  • Page 16 K-factor values programmed into them. Unlike standard mechanical flow meters such as turbines, gear or nutating disk meters, the K-factor of the FUSION meter can be changed by modifying the FULL FLOW flow rate value. Please refer to the equations on the following page for the Full Flow / K-factor Calcu- lation.
  • Page 17 Rate Pulse Output Connection Figure 10 illustrates the field wiring terminals and switch set- tings utilized for the rate pulse output. Full Flow / K-factor Calculation The Rate Pulse output generates 1,000 Hz (pulses per second) at full flow. To adjust the K-factor of the meter, adjust the full flow entry.
  • Page 18 Total Pulse output examples, Example 1: If the Total Unit is set to Gallons and the Total Multi- plier is set to E0 (x1), the FUSION will output one pulse for every gallon of liquid that passes through the meter.

    4. FUSION POWER-UP FUSION Firmware Version After power is applied to the FUSION flow meter, the display will illuminate and show the software version that is running inside of the flow meter as Ux.xx. Have the firmware version available when contacting factory technical support personnel so that more effective service can be provided.

    6. CONFIGURATION The FUSION meter has two basic sets of programming proce- dures: list item selection and entering of numeric values. It also has two configuration menus—Basic and Advanced. Important: The FUSION software is structured using two menus—a Basic menu and an Advanced menu.
  • Page 21 Basic Menu Items The Basic Menu contains standard configuration items that are utilized to setup a FUSION flow meter in common applications. The following items are available for viewing and modification in the Basic Menu:...
