Applications
Differential Pressure Flow (PD6262)
The PD8-6262 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
Open Channel Flow (PD6262)
The PD8-6262, in combination with ultrasonic level transmitters, makes for an easy and convenient 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 PD8-6262 and the PD8-6262 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.
Weir Flow Calculated Using Exponential Signal Input Conditioning
Convert Pulse to 4-20 mA (PD6363)
The PD8-6363 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 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:
- 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.
