Feature Rich and Flexible
The ProVu® meter boasts specifications and functionality that clearly make it one of the most advanced process meters available. Its dual-line 6-digit display (999,999), advanced signal input conditioning, function keys, Modbus RTU serial communications, and optional expansion modules are only a few of the features found on the ProVu PD6000.
FRONT PANEL DISPLAY
Precise, Accurate, and More Informative
ProVu's large 0.6" upper display provides a highly accurate and precise 6-digit view of the process measurement. Its 24-bit A/D is accurate to ±0.03% of calibrated span ±1 count.
The upper display can be programmed to indicate PV, maximum (peak), minimum (valley), alternating maximum/minimum, one of eight alarm set points, or Modbus input. The lower display can also be configured to display engineering units, set points, user defined legends, or simply turned off.
Optional SunBright Display Models
ProVu's SunBright display models have an extraordinarily bright LED display. They are perfect for applications where the meter is in direct sunlight or in applications where visibility may be impaired by smoke, fog, dust, or distance. Option is available on all ProVu models.
There are three function keys available to the user. These keys can be programmed to trigger certain events (i.e. acknowledge alarms, reset max and/or min, disable/enable output relays, or hold current relay states), provide direct menu access points, and more.
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.
Easy to Use
The user friendly dual-line display makes the ProVu easy to set up & program. No jumpers to set for input selection. All setup & programming is done via the front panel. Three levels of password protection help maintain the reliability of the programming.
Dual-Scale Display Feature
The ProVu PD6000 has a rather unique and very flexible dual-scale capability; a second scaled display can represent the measured input in a different form (i.e. gallons & height). This is of particular value in level applications. Please see the examples shown below. Both displays are independently scaled and are based on the 4-20 mA input signal. Beyond level, this function has been used for pressure & force, current & power, feet & meters, GPM & CFM, and more.
Gallons and mA
Gallons and Height
Gallons and Percent
Gallons and Head PSI
Three Tier Password Protection
The ProVu offers 3 levels of password protection:
Level 1 protection allows the operator use of only the 3 pre-configured function keys on the front panel without a password.
Level 2 protection allows the operator use of only the function keys and the ability to change set points without a password.
Level 3 protection restricts the operator from using the function keys and all meter configuration menus without a password.
Advanced Linearization Capability
The ProVu includes a 32-point linearizer. In non-linear level applications (i.e. some pumping or lift stations), it can easily compensate for submerged equipment or plumbing that displace usable volume. A second independent 8-point linearizer is available for a second scaled display (PV2) when "Level" function is enabled. Precision Digital's free MeterView Pro PC-based software greatly simplifies the construction of the linearization tables. The software can save this data to the meter and/or PC.
On-Board Digital Input
The PD6000 includes a digital input as standard. This digital input can operate with the tare, reset tare, or interlock relays feature, force relays on from a signal from a PLC or relay on other equipment, and much more. This is ideal for installations where the meter is inaccessible behind a cover, or where an additional function key is needed for customized operation.
The rounding feature is used to give the user a steadier display with fluctuating signals. It causes the display to round to the nearest value according to the rounding value selected (1, 2, 5, 10, 20, 50, or 100). For example, with a rounding value of 10, and a input of 12346, the display would indicate 12350.
Max/Min (or Peak/Valley) is standard on the ProVu PD6000. Either display can be configured to show either maximum or minimum excursion since last reset. The displays can also be configured to toggle between Max and Min values. Both values can be simply reset from the front panel
Modbus® RTU Serial Communications
With the purchase of a serial communication adapter, ProVu meters can communicate with any Modbus Master device using the ever-popular Modbus communications protocol that is included in every ProVu. This greatly increases the flexibility of the meter. Modbus provides much more capability than read PV and write set points. Below are some examples of other things that can be done with ProVu's Modbus communications.
Send a 6-character message to the lower display upon an event
Convert a digital value to a 4-20 mA signal
Remote user control (i.e. change set points, acknowledge alarms)
Input a Modbus digital PV (in place of analog input)
Remote override of any, or all, relays and analog outputs
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.
Watch a quick demonstration on how the ProVu works and also how the function keys can simplify functionality. These and other videos are available click here.
FIELD EXPANSION MODULES
Add functionality to the ProVu in the field with easy-to-install external expansion modules. Add RS-232, RS-485, or USB communications, digital I/O modules (up to 2), and a 4-relay expansion module, for a possible 4 total expansion modules. 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 with optional DIN rail mounting kit, P/N PDA1002. These expansion modules connect to the ProVu via an M-Link cable which is provided with each expansion module..
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.
PDA1044 Digital 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.
roVu at anytime. Removable screw terminal blocks accept 12 to 22 AWG wire.
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.
Free Modbus protocol with purchase of ProVu serial communications modules. MeterView Pro free monitoring and control software is also available for use with these adapters..
METERVIEW® PRO SOFTWARE
Configure, monitor, and datalog a ProVu PD6000 from a PC using MeterView Pro Software (available for download here and a serial adapter. here.
Monitor and Datalog
The ProVu has up to four 3 A Form C relays (SPDT) with multiple power loss fail-safe options. 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
The isolated analog retransmission signal can be configured to represent the process variable (PV), maximum (peak) value, minimum (valley) value, the value for any of the eight relay set points, or Modbus input. While the output is nominally 4-20 mA, the signal will accurately accommodate under- and over-ranges from 1 to 23 mA.
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.
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.
Sampling Function (PV Triggered Timed Relay)
The sampling function allows the operator to set a set point for a "sampling" relay. When the PV 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 beer/ale fermentation. When the batch reaches a certain pH, the relay contacts would close and by some means (light, horn, etc.) alert someone to take a sample, or provide the trigger to automatically take a sample of the batch. 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 PV 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 on our website for more information. Requires PDA1044 Digital I/O module or use of on-board digital input F4. Note: Requires PDA1044 Digital I/O module.
SIGNAL INPUT CONDITIONING
Non-linear input signals (i.e. weirs & flumes, differential pressure, etc.) can be linearized with the ProVu's simple to use built-in signal input conditioners, such as: square-root extractor, exponential linearizer, horizontal round tank linearizer, or the ProVu's powerful general purpose 32-point linearizer.
Weir Flow Calculated Using Exponential Math Function
For pump control applications where 2 or more similar pumps are used to control the level of a tank or a well, it is desirable to have the pumps operate alternately; this prevents excessive wear and overheating of one pump over the lack of use of the others. The ProVu can accommodate up to 8 pumps. In the example below, a pair of relays have been set up to alternate every time an on/off pump cycle is completed. Another pair of relays is used for low and high alarms.
Relay #4 turns the main pump on at 6000 gallons and turns it off at 1000 gallons.
With the Pump Alternation feature activated, the next time the level reaches 6000 gallons, relay #3 transfers and starts the backup pump.
If the backup pump is not able to keep up, and the level reaches 7000 gallons, relay #4 transfers and starts the main pump as well.
Relay #2 trips the High Level Alarm at 7500 gallons and resets at 6900 gallons.
Relay #1 trips the Low Level Alarm at 495 gallons and resets at 750 gallons.
