    LED flow display and a traditional style electronic pressure indicator into one practical display module. The flowmeter/pressure indicator is able to communicate with other display modules over the FRC datalink. This technology allows for remote displays, the display of flow for multiple discharges (summing), and the totalization of flow for multiple discharges (accumulation).

  • Page 7: Controls And Indicators

    FPA400 Rev160601 Controls and Indicators All controls and indicators are located on the front of the display module. It contains the pressure scale and indicating needle, a digital display, and the three magnet sensors. (Refer to Figure 1.) Pressure Pointer The pressure scale is non-linear and is expanded between 100 and 250 PSI.

  • Page 8: Installation

    FPA400 Rev160601 INSTALLATION Note: Plumbing systems are always unique and may cause small deviations in the factory calibration. It is recommended that the flowmeter/pressure indicator is checked after installation for accuracy and calibrated when necessary. Install Display Module Display modules are interchangeable. It is recommended to check display accuracy if modules are swapped and calibrated when necessary.

  • Page 9: Install Pressure Sensor

    FPA400 Rev160601 Install Pressure Sensor The pressure sensor is mounted downstream of the discharge valve. Pressure sensors are interchangeable. It is recommended to check display accuracy if sensors are swapped and calibrated when necessary. Note: Install the pressure sensor upright so water in the end of the sensor drains back into the pipe.

  • Page 10: Install Flow Sensor

    FPA400 Rev160601 Install Flow Sensor There are several ways to install paddlewheel type flow sensors. Mounting options include saddle clamps, weldments, pipe tees, and special adapters. Each mount meets a particular plumbing requirement. Flow sensors are interchangeable. It is recommended to check display accuracy if sensors are swapped and calibrated when necessary.

  • Page 11: Figure 4. Flow Sensor Location Guide

    FPA400 Rev160601 Flow Sensor Location Guide The preferred location for mounting a flow sensor is on the top half of the pipe. The best orientation is vertical. If the sensor is mounted on the bottom of the pipe, it may be susceptible to dirt Best Orientation accumulation impacting operation.
  • Page 12 FPA400 Rev160601 Saddle Clamp Installation Note: Ensure that the mounting location meets the requirements for uniform water flow. (Refer to Flow Sensor Location.) Note: Ensure that there is enough room for the saddle clamp, sensor, and connector to fit. (Refer to Figure 5.) 1.

  • Page 13: Figure 5. Saddle Clamp Installation

    FPA400 Rev160601 Retainer Note: When the retainer cap is tightened make sure the flow sensor engages the alignment O-Ring tab and does not rotate. Paddlewheel Flow Sensor Note: Allow a minimum of Alignment 2 inches clearance above the sensor for connector removal/ installation.
  • Page 14 FPA400 Rev160601 Weldment Installation Note: Ensure that the mounting location meets the requirements for uniform water flow. (Refer to Flow Sensor Location Guide.) Note: Ensure that there is enough room for the weldment, sensor, and connector to fit. (Refer to Figure 6.) 1.

  • Page 16: Operation

    Datalink Interface The datalink interface provides a way of connecting multiple display modules on a shared data bus. The DFA400 (digital flowmeter), FPA400 (pressure/flow indicator), and FPA500 (pressure/flow indicator) series display modules can operate as independent displays or interconnected to provide remote displays, the display of flow rate through multiple discharges (summing), and the totalization of flow for multiple discharges (accumulation).

  • Page 17: Program Features

    FPA400 Rev160601 Program Features See Programming Section for more detailed information. High and Low Flow Warning (Codes 315 and 316) When the flow rate is above the programmed high flow value, a flashing -HI- is shown in the digital display. When the flow rate is below the programmed low flow value, a flashing -LO- is shown in the digital display.

  • Page 18: Programming

    FPA400 Rev160601 PROGRAMMING The two operator selectable modes are display module identification and program access. These modes are selected and inputs are made using the three magnet sensors on the front of the display module. The digital display shows stored data and operator inputs.

  • Page 19: Program Access Mode

    FPA400 Rev160601 Program Access Mode To gain access to the program features a three digit program code must be entered. Review the Program Code Descriptions or refer to Table 2. Program Code Quick Reference for the proper three digit code.

  • Page 22: Program Code Descriptions

    FPA400 Rev160601 Program Code Descriptions When a valid three digit program code has been entered a program value or option will show in the display. The M1 and M2 sensors are used change the data. The M1 sensor selects the digit that is to be changed. The digit flashes.
  • Page 23 FPA400 Rev160601 Code 316 Low Flow Warning Factory programmed value: 0 (Low flow warning is disabled.) Options: 0001 to 9999 This code sets the low flow warning. When the flow rate is below the low flow warning programmed value, the flow display alternately flashes between the flow rate and -LO- .
  • Page 24 FPA400 Rev160601 Code 321 Flow Calibration (Single Point) Factory programmed value: Precalibrated to Pipe Size Options: 1 Calibration Point This code starts the calibration program for a single flow rate. Refer to Calibration Section. Code 322 Flow Calibration (Multiple Point)
  • Page 25 FPA400 Rev160601 Error Code E202 An invalid program code has been entered. Re-enter the program code when the digital display resets. Error Code E204 There is no signal from the sensor. This code is displayed only when in a calibration program.

  • Page 26: Calibration

    FPA400 Rev160601 CALIBRATION The flowmeter/pressure indicator is precalibrated and tested at the factory. Plumbing systems are always unique and may cause small deviations in the factory calibration. It is recommended that the flowmeter/pressure indicator is checked after installation for accuracy and calibrated when necessary.

  • Page 27: Flow Calibration, Multiple Point (Code 322)

    FPA400 Rev160601 Flow Calibration, Multiple Point (Code 322) This function is used when the flow sensor is installed in a difficult plumbing location where flow is not linear. It corrects for nonlinear flow to provide an accurate flow rate display.

  • Page 28: Pressure Calibration (Code 323)

    FPA400 Rev160601 Pressure Calibration (Code 323) Note: To calibrate the pressure indicator, use a precalibrated pressure indicator or gauge as a reference. There are two pressure calibration points available in the program. 1. Enter code 323. Result: The digital display shows Pt1 (program is ready to set the first calibration point).
