The Precision Digital ProtEX-MAX™ PD8-6300 offers all the functionality of the ProVu PD6300 as a fully IECEx, ATEX, CSA, and FM approved explosion-proof product. It is specifically designed to display flow rate and totalizer from a pulse output (PNP, NPN, switch contact, sine wave, TTL, etc.) flowmeter. It displays that signal on a dual-line with 6-digit Sunbright sunlight readable display. Flow rate is typically displayed on the upper line and the totalizer is displayed on the lower line. The totalizer overflow feature allows up to a 9-digit total and grand total to be displayed. The PD8-6300 includes a 24 VDC transmitter power supply to drive the flowmeter and can be equipped with a 4-20 mA analog output and up to four internal relays. It can be programmed and operated without opening the housing by using the built-in SafeTouch®through-glass buttons or the RS485 serial communication port with free Modbus®protocol.

MeterView® Pro Software
MeterView® 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 familiar 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:
- Go to the Diagnostics menu () and press the Enter button.
- Press Up arrow button and scroll to Information menu (Info).
- 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.
- The meter returns to Run Mode after displaying all the settings.
