The ProtEX-MAX™ PD8-6200 offers all the functionality of the ProVu PD6200 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. It is specifically designed to display flow rate and total from an analog output (4-20 mA, 0-5 V, 1-5 V, etc.) flowmeter. It displays that signal on a dual-line, 6-digit Sunbright sunlight readable display. Flow rate is typically displayed on the upper line and the cumulative total is displayed on the lower line. The total overflow feature allows up to a 9-digit total and grand total to be displayed. The PD8-6200 includes a 24 VDC power supply to drive the flowmeter and can be equipped with up to four internal relays and a 4-20 mA analog output. 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.

Differential Pressure Flow
The PD8-6200 can display flow rate and total by extracting the square root from the 4-20 mA signal from a differential pressure transmitter. The user selectable low-flow cutoff feature gives a reading of zero when the flow rate drops below a user selectable value.
- Display Flow Rate
- User Selectable Low-Flow Cutoff
- Only 2 Calibration Points Required
Convert Pulse to 4-20 mA with PD6300
The PD8-6300 accepts the pulse output from a flowmeter and with the appropriate option installed can convert the pulse 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
- Display Flow Rate & Total
Open Channel Flow
The PD8-6200, in combination with an ultrasonic level transmitter, makes for an easy and convenient way to measure and display open channel flow rate and total in most weirs and flumes and take periodic samples. All the user needs to do is enter the exponent for the weir or flume into the PD8-6200 and the PD8-6200 automatically raises the input signal to that power. Sampling can be based on the total flow or the flow rate. For instance, to display open channel flow rate and total from a 3 inch Parshall flume and take a one pint sample every 100,000 gallons, the user would program the PD8-6200 as follows:
|Open Channel Flow||3″ Parshall flume||Set Programmable Exponent to 1.547|
|Flow Rate||Millions of Gallons per Day (MGD)||Set 4 mA = 0 & 20 mA = 3.508|
Time base = Day
|Total||Millions of Gallons||Set Totalizer Conversion Factor = 1|
(password protect total reset)
|Non-Resettable Grand Total||Program meter so grand total can never be reset||Set non-resettable grand total password|
|Display||Display Flow Rate and Total at the same time||Set main display for Grand Total and secondary display to toggle between rate and total|
|Sampling||Take a 1 pint sample every 100,000 gallons||Set up relay for sampling and to trip every 0.1 million gallons. Set up sampling time such that 1 pint is sampled|
Total Relay Sampling Operation
MeterView® Pro Software
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 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.
