FRONT PANEL DISPLAY
Display Flow Rate, Total or Grand Total
The main display can be programmed to display flow rate, total or grand total, and the secondary display can be programmed to display flow rate, total or grand total, engineering units, custom legends or can be turned off. Both displays could also display relay set points or max and min values.
In the graphic above, the main display is displaying flow rate (as indicated by the gRh to the right of the number) and the secondary display is displaying flow total (as indicated by the T under the number.) The following photographs show typical ways these flow rate/totalizers can be programmed:
Totalizer Overflow Displays Total to 9 Digits
These flow rate/totalizers can display up to nine digits of total flow with the total overflow feature. In the diagrams below, the flow totalizer is displaying 532,831,470 by toggling between a display of goF 532h and g831470h. Notice the (T with arrow £ symbol) is lit up indicating the display is in overflow mode.

Rugged
| A unique front panel design makes the ProVu nearly impenetrable in typical applications. Here, the ProVu easily survives a direct hit on the display from a heavy 2" solid stainless steel ball dropped from eight feet. |
 |
TOTALIZER CAPABILITIES
These ProVu flow rate/totalizers can be programmed for a wide variety of totalilzer applications. They can display total, grand total, or non-resettable grand total with a time base of seconds, minutes, hours or days. The user can program a totalizer conversion factor, a non-resettable grand total, password protection and several total reset methods.
Non-Resettable Grand Total
The user can set up the grand total to be non-resettable by entering a specific password. Once this is done, the grand total can never be reset.
Totalizer Conversion Factor
The user can enter a totalizer conversion factor that allows the meter to display total in different units than the rate. For instance, a customer could measure flow rate in gallons per minute and total in hundredths of acre-feet.
Password Protection
The total and grand total can be password protected so they can be reset only by authorized personnel.
 |
 |
| Total Password |
Grand total Password |
Front Panel Total Reset
The three front panel function keys can be programmed to reset the total and grand total. This makes it possible for the user to reset either the total or the grand total by pressing the appropriate function key. Of course, if the total or grand total is password protected, they will not reset when the function key is pressed. |
 |
|
| |
Remote Total Reset
An I/O expansion module can be used to remotely reset the total or grand total. The reset switch is wired into the module and the module is connected to the M-Link RJ45 socket at the back of the flow rate/totalizer.
Total Alarms
The ProVu’s four internal and four external relays can be set up to alarm when the total reaches a user-defined set point. A variety of reset modes are available and the user can also program time delays and fail safe operation.
FIELD EXPANSION MODULES
Add functionality to the ProVu in the field with easy-to-install external expansion modules. Add RS-232 or
RS-422/485 communications, I/O modules (up to 2), or 4-relay expansion module. The menu items for these modules do not appear until the module is connected, simplifying the basic menu. Relay and digital I/O modules
are shown below with optional DIN rail mounting kit, P/N PDA1002.
I/O Expansion Module
Four digital inputs and four digital outputs are available per expansion module. The ProVu meter will accept two of these modules. External digital inputs can function similarly to the front panel function keys. They can be configured to trigger certain events (i.e. reset total or grand total, acknowledge/reset alarms, reset max and/or min values, disable/enable all output relays, and hold current relay states), and provide direct menu access point.
Digital outputs can be used to remotely monitor ProVu’s alarm relay output states, or the states of a variety of actions and functions executed by the meter.
Relay Expansion Module
An external module containing four 3 amp Form A (SPST) relays can be added to the ProVu at anytime. Removable
screw terminal blocks accept 12 to 22 AWG wire.
|
 |
 |
Communications Module
Serial communications on the ProVu can be added anytime with external RS-232 or RS-422/485 communication adapters.
|
OUTPUTS
| Relay Outputs |
 |
| The ProVu has up to four 3 A Form C relays (SPDT), giving you more fail-safe options upon power loss. Relay action can also be configured for input loop break protection. Set ON and OFF delay times when needed. Up to eight front panel indicators show alarm and/or relay state. All relays can be configured for 0-100% deadband. |
Relay Operation & Configuration
There are powerful relay functions that can be configured in the meter, including:
Automatic reset only (non-latching)
Automatic + manual reset at any time (non-latching)
Latching (manual reset only)
Latching with clear (manual reset only after alarm condition has cleared)
Sampling (activated for a user-specified time)
User selectable fail-safe operation
Relay action for loss (break) of 4-20 mA input signal
Time delay (on and off), independent for each relay
Manual control mode
Analog Output
The isolated analog retransmission signal can be configured to represent the rate, total, grand total, maximum (peak) value, minimum (valley) value, or the value for any of the eight relay set points. While the output is nominally 4-20 mA, the signal will accurately accommodate ranges from 1 to 23 mA.
Auto/Manual Control
Take control of any output with this feature. All relays can be forced ON or OFF, and the 4-20 mA output signal can be set to any value within its range. This is particularly useful for valve control applications.
Isolated Transmitter Power Supplies
A powerful 24 V @ 200 mA power supply is a standard feature on the ProVu meter. It can be configured for 5, 10, or 24 V (default) by means of a simple internal jumper (see manual). An additional power supply (24 V @ 40 mA) is standard with the 4-20 mA output option.
NEMA 4 & 4X FIELD ENCLOSURES
Plastic, stainless steel, and painted steel NEMA 4X enclosures for up to 10 ProVu meters.

EASY PROGRAMMING AND SETUP
Dual-Line Display & 4 Buttons
The user friendly dual-line display and four programming buttons make the ProVu easy to set up and program. The four buttons keep the user in control of the programming process, and the second line provides a reminder or prompt for the current programming step.
 |
 |
| Input 1 |
Display 1 |
The meter on the left is prompting the user to enter the desired input value, which in this case will be 4 mA. A key feature of the ProVu is that it is not necessary to actually apply this input so the meter can be scaled without a calibrator.
The meter on the right is prompting the user to enter the desired display value that corresponds to Input 1. The right arrow moves the active digit to the right and the up arrow increases the value of the digit.
I/O Module for Remote Programming
The I/O module can be used to program the ProVu remotely, in essence giving the user control of the four front panel push buttons. This feature is particularly useful if the meter is mounted inside an explosion-proof enclosure.
METER COPY
The Copy feature is used to copy (or clone) all the settings from one ProVu to other ProVu meters in about 20 seconds! The Copy function is a standard feature on all meters. It does not require a communications adapter, only an optional cable assembly, P/N PDA1200. See the ordering information for complete details.
Copying Meter Settings
APPLICATIONS
Open Channel Flow
The PD6200, in combination with an ultrasonic level transmitter, makes for an economical 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 PD6200 and the PD6200 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 PD6200 as follows:
| Function |
Desire |

| Flow Rate |
Millions of Gallons per Day (MGD) |
Set 4 mA=0 & 20 mA=3.508
Time base=Day |
| Total |

| 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 |
Differential Pressure Flow
The PD6200 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 PD6300 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.
