PERFECT FOR FLOW APPLICATIONS
The PD6262 and PD6363 ProVu meters are multipurpose, easy to use digital dual analog/pulse input flow rate/totalizers specifically designed for displaying flow rate and total from flowmeters with analog or pulse outputs. The displays, relays, and the analog/pulse outputs may be assigned to the rate, total, or grand total of input channels A or B; or math result channel C. Three of the front panel buttons can be custom-programmed for a specific operation.
Dual-Input Process Meter
The PD6262 has two process input channels (A & B) capable of accepting current (0-20, 4-20 mA) and voltage (±10, 0-5, 1-5, 0-10 VDC). The PD6363 accepts two pulse (e.g. ±40 mV to ±8 V), square wave (0-5 V, 0-12 V, or 0-24 V), open collector, NPN, PNP, TTL or switch contact signals. Each input is programmed separately, with independent input type selection and scaling. These inputs may be displayed individually as part of the customizable dual-line display, or used with a wide range of math functions.
Powerful Math Functions
The PD6262/PD6363 uses two rate input channels (A & B) with total and grand total for each in a variety of powerful math functions designed for a wide range of flow applications. Programmable adder (P) and factor (F) constants allow each formula to be customized as needed for a specific application. The math function (C) may be displayed with units, tags, channel A or B, rate, total or grand total, and in other useful combinations.
|Max of A or B
|Min of A or B
|G. Tot. Addition
|G. Tot. Difference
Note: t = total, Gt = grand total. The F constant can be any value from 0.00001 to 999999. If the value is less than 1, it will have the same effect as a divider. For example, the average could also be derived by using (A+B)*F, where F = 0.500.
The ProVu has two red LED displays, an Upper display 0.60" (15 mm) high, and a Lower display 0.46" (12 mm) high. Each display is a full 6 digits (-99999 to 999999). The displays can be set up to read input channels (A or B), rate, total, or grand total, math function channel C, toggle between A & B, B & C, A & C, A & B & C, toggle between channels A, B, or C & units, the max/min of any of the channels, including the math channel (C), set points, or the Modbus input. This allows the display to be setup to display whatever variables are most valuable to the application. Here are just a few examples.
|Math Function & Tag
The Upper display shows the math function result (C). The Lower display shows a custom label, in this case the math function used.
|Math Function & Totals A & B
The Upper display shows the math function result (C). The Lower display alternates between totals A and B, with an indicator for each when being displayed.
|Input Channels A & B Total
Both input channels are displayed, input A total on the Upper display and input B total on the Lower display. Indicators show A or B to label the display channel.
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 "oF 532" and "831470". Notice the "oF" stands for overflow.
Simplified & Dynamic Menu System
The ProVu minimizes the menu selections by auto-detecting the installed options to determine what menu navigation is required. For example, extra menu items for the relay expansion module, I/O expansion, etc. are not present unless those options have been installed.
A unique front panel design makes the ProVu digital panel meter 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.
Optional SunBright Display Models
ProVu's SunBright display models have an extra bright LED display. They are perfect for applications where visibility may be impaired by direct sunlight, smoke, fog, dust, or distance. Option is available on all ProVu models.
Certain display options alternate the display information. A single display can show input variable information as well as that channel's unit or tag. Input and math function channels, gross and net values, and select inputs and the math result may also alternate on a single display. Below are just a few of the options for setting up a single display to alternate information.
The ProVu has standard UV protection, a NEMA 4X front panel, extremely durable face plate, performs in a wide ambient operating temperatures, and is CE Certified (high noise and RF immunity).
Modbus® RTU Serial Communications
With the purchase of a serial communication adapter, ProVu meters can communicate with any Modbus Master device using the everpopular Modbus communications protocol that is included in every ProVu. This greatly increases the flexibility of the meter.
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.
METERVIEW® PRO SOFTWARE
ProVu series meter using the PC-based MeterView Pro (MVP) software (serial communications adapter required). MVP makes complete meter configuration simple and fast. Copying one meter configuration to another, as well as saving or retrieving a meter configuration file is a snap. MVP's linearization utility makes even a 32-point linearization task clear and easy to do. We also included a basic meter monitor and data logger for use with a ProVu. Of course, with ProVu's powerful Modbus protocol, custom programs can be made even more versatile. For more details on MeterView Pro, click here.
ProVu flow rate/totalizers can be programmed for a wide variety of totalizer applications. Each input channel has a 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 for each channel, 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 for each channel that allows the meter to display total in different units than the rate. For instance, a meter could display flow rate in gallons per minute and total in hundredths of acre-feet.
Totalizer Password Protection
The total and grand total can be password protected so they can be reset only by authorized personnel
Remote Total Reset
An I/O expansion module or F4 digital input can be used to remotely reset the totals or grand totals. The reset switch is wired into the module or F4 input and the module is connected to the M-Link RJ45 connector at the back of the flow rate/totalizer.
The ProVu's four internal and four external relays can be set up to alarm when the total of channel A or B, or channel C math based on the totals, 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.
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.
FIELD EXPANSION MODULES
Add functionality to the ProVu in the field with easy-to-install external expansion modules. Add RS-232 or RS-485 communications, I/O modules (up to 2), and 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 to the right with optional DIN rail mounting kit, P/N PDA1002.
PDA1004 Relay Expansion Module
An external module containing four 3 A Form A (SPST) relays can be added to the ProVu at anytime. Removable screw terminal blocks accept 12 to 22 AWG wire.
PDA1011 Dual Analog Output Expansion Module
The PDA1011 is a dual analog output expansion module that is connected to the meter using a CAT5e cable provided with each module. For the ProVu to recognize installed PDA1011 analog outputs the module must be connected by the M-Link connector to the ProVu and each analog output to be used must be wired to and powered by a separate DC supply powering the ProVu.
Note: Works with dual-input meters only.
PDA1044 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 or on-board digital input F4. They can be configured to trigger certain events (i.e. acknowledge/reset alarms, reset max and/or min values, disable/enable all output relays, and hold current relay states), provide direct menu access point, or mimic front panel keys. The I/O module can be used to configure 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.
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.
PDA1232, PDA1485, & PDA8008 Communication Modules
Serial communications on the ProVu can be added anytime with external PDA1232 (RS-232), PDA1485 (RS-485), or PDA8008 (USB) communication adapters.
Each isolated analog retransmission signal can be configured to represent the channel A or B rate/process variable (PV), total, grand total, maximum (peak) value or minimum (valley) value; Channel C; math value; or the value for any of the eight relay set points, manual setting control, or Modbus input. While the output is nominally 4-20 mA, the signal will accurately accomodate under and over ranges from 1 to 23 mA.
The ProVu has up to four 3 A Form C relays (SPDT) with multiple power loss fail-safe options. Each relay may be assigned to input channel A or B, rate, total or grand total, or math result (C). Relays can be configured for proper protective action upon input loop break. Relay ON and OFF delay times are user adjustable. Up to eight front panel indicators show alarm and/or relay state. All relays can be configured for 0-100% deadband.
There are powerful relay functions that can be configured in the ProVu 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)
- Pump alternation control (automatic reset only)
- 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
- Interlock relay mode
Manual Output 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. When the relays and 4-20 mA output are controlled manually, an LED labeled "M" is turned on and the associated Alarm LEDs (1-8) flash every 10 seconds indicating that the meter is in manual control mode.
Sampling Function (PV Triggered Timed Relay)
The sampling function allows the operator to set a set point for a "sampling" relay. When the process (rate or total) reaches that set point, it will close that relay's contacts for a preset period of time (0.1 to 5999.9 seconds). An example of its use may be for wastewater sampling. When the wastewater total reaches a preset total interval (i.e. every 10,000 gallons), the relay contacts would close for a preset time, and by some means (light, horn, etc.) alert someone to take a sample, or provide the trigger to automatically take a sample of the wastewater. The utility of this function can, of course, be expanded beyond sampling and be used whenever a timed relay output closure is required when the rate or a total interval reaches a certain set point.
This function allows a process to use one or more very low voltage input signals or simple switch contacts to control the state of one or more internal "interlock" relays. A violation (i.e. loss of input, open switch, or open circuit) forces one or more N/O interlock relay contacts to open. One input can be used in series with a number of interlock switches, or up to eight inputs can be required to force-on one (or more) internal interlock relays. Please see Application Note AN-1008 for more information. Requires PDA1044 Digital I/O module or use of on-board digital input F4.
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
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
