    Wiring Diagram:

    The PD6363 is a member of the ProVu series of 1/8 DIN digital panel meters that is specifically designed to display flow rate and total from two (2) pulse output (NPN, PNP, TTL, switch contact, sine wave, etc.) flowmeters. It displays these signals on a dual-line, 6-digit display that is available with optional Sunbright® sunlight readable LEDs. The dual-line display can be used to show both flow rates simultaneously, to alternate between the two inputs showing both the flow rate and total of each, or to show the result of math functions performed on the flow rates and totals. Like all ProVu meters, the PD6363 includes UL / C-UL listing and CE marking, a NEMA 4X front, and AC or DC power options. ProVu meters can be equipped with up to four internal relays, a 4-20 mA output, and Modbus® RTU serial communications. The PD6363 dual-input flow rate/totalizer includes a 24 VDC power supply to drive the flowmeter and can be programmed via the front panel pushbuttons or free MeterView® Pro software.

    Total & Grand Total Reset: Via front panel button, external contact closure on digital inputs, automatically via user selectable preset value and time delay, or through serial communications. Channel A and B total and grand total reset parameters programmed independently.
    Total Reset Password: Total and grand total passwords may be entered to prevent resetting the total or grand total from the front panel.
    Non-Resettable Total: The grand totals can be programmed as non-resettable totals by entering the password “050873”. Both channels are set to non-resettable when this password is entered. Caution: Once the Grand Total has been programmed as “non-resettable” the feature cannot be disabled.
    Programmable Delay on Release: 0.1 and 999.9 seconds; applied to the first relay assigned to total or grand total. If the meter is programmed to reset total to zero automatically when the preset is reached, then a delay will occur before the total is reset.

    Differential Pressure Flow (PD6262)

    The PD6262 can display flow rate and total by extracting the square root from the 4-20 mA signal from differential pressure transmitters. The user selectable low-flow cutoff feature gives a reading of zero when the flow rates drop below a user selectable value.

    • Display Flow Rate
    • User Selectable Low-Flow Cutoff
    • Only 2 Calibration Points Required

    Weir Flow Calculated Using Exponential Signal Input Conditioning

    Open Channel Flow (PD6262)

    The PD6262, in combination with ultrasonic level transmitters, makes for an economical way to measure and display open channel flow rates and totals in most weirs and flumes, and take periodic samples. All the user needs to do is enter the exponents for the weirs or flumes into the PD6262 and the PD6262 automatically raises the input signals to those powers. Sampling can be based on the total flow or the flow rate. Each channel’s signal input conditioning is programmed independently.

    Convert Pulse to 4-20 mA (PD6363)

    The PD6363 accepts pulse outputs from flowmeters and with the appropriate option installed, can convert the pulses to a 4-20 mA signal. The 4-20 mA signal can be programmed to correspond to either the flow rate or the total flow.

    • Use K-Factor or Multi-Point Scaling
    • ProVu Powers the Flowmeter
    • Up to 3 Analog Outputs

    MeterView® Pro Software

    MeterView Pro VideoMeterView® Pro software is designed for use with ProVu, ProtEX-MAX, or Helios Series meters and allows users to remotely program, monitor, and datalog using a PC. Remote programming allows for all available meter settings to be programmed through an easy, user-friendly interface. The data acquisition feature allows the user to gather readings from a meter at user-selected intervals and generate charts using common tools like Microsoft® Excel. A linearization setup function is also included. With this utility the user can configure up to 32 linearization points and upload them to the meter. All configuration data can be saved to a file for future use.
    This software is accessible via the onboard USB connection on all Helios large display meters, ProVu panel meters, and ProVu-based ProtEX-MAX explosion-proof meters produced since 6 September 2016 (firmware version 4.0 or higher). In order for meters produced prior to 6 September 2016 (firmware version 3.1 or lower) to establish digital communications with a PC, a serial communications adapter is required. For an RS-232 connection, use a PDA1232 adapter.
    To determine the software version of a meter:

    1. Go to the Diagnostics menu () and press Enter button.
    2. Press Up arrow button and scroll to Information menu (Info).
    3. Press Enter to access the software number (), version (), and serial number () information. Write down the information as it is displayed. Continue pressing Enter until all the information is displayed.
    4. The meter returns to Run Mode after displaying all the settings.
