System Highlights

VESTA’s software is an open design with a communications DLL provided to customers (with executed NDA) allowing them to easily interface into existing systems. The goal is for customers to design new applications which can be distributed to other customers for enhanced flexibility. All AEP bar codes are already loaded into the database and can be easily modified. The heart of VESTA is its true 3-Phase 100 Amp standard, which also has a voltage and current output. The combination of pulses, volts and amps provides a dual reference for accuracy. The voltage and current amplifiers are Type AB Audio amplifiers, which provide distortion-free sine waves. The jaw system is truly unique compared to those used by our competitors. The jaws are motor driven and very quiet. Other manufacturers use coils which make a loud noise when opening and closing..

Everything in Vesta is controllable and programmable. All timers used for settling with electronic meters are variable to minimize testing time. The optical probe can be used to test the meter and communicate with the meter via the manufacturers software. Programming Vesta to test a meter and then reset registers can be accomplished without changing the probe or moving the pulse pick up arm. With electronic meters, there is no need for a pulse pick up arm. VESTA has a user defined data export function with which data can be exported in CSV or text file from the SQL database.

Itron Centron™ meters can be tested without the use of a movable arm. The sensor is aligned when the meter is mounted in the socket.

While Vesta comes with an adjustable arm, it should only be necessary for testing mechanical meters either through the holes in the disk or on the disk edge.

Some meters require either a snake arm or adjustable arm to test such as the Itron™Sentinel. By using the Snake Arm, the optical port is unencumbered and easily used for programming and resetting the meter. The Snake Arm can also be used to test other Itron meters as well as Sensus. Some meters are shipped without a steel piece in the optical port so using the Sentry 410 is not feasible.

Vision strives for minimal use of the adjustable arm to achieve improved production.

What Separates VESTA from its Competitors?

  • VESTA is designed as a production test platform - Vision Metering is the largest privately held metering test lab in the country and tests 100’s of thousands of meters every year. VESTA is saving Vision Metering untold man hours in test time per year. More meters can be tested with less equipment and manpower.
  • VESTA utilizes an industrial touch screen for all operations thus eliminating the need for a keyboard or mouse. While a wireless keyboard and mouse are included, they are only used when using other manufacturers software and database manipulation. The touch screen minimizes testers movements and speeds the process significantly.
  • VESTA uses specially designed auto alignment sensors to test certain meters like Itron™ Centron meters where the infrared pick up is located on the top and the Sensus™ Icon meters where the sensor is located on the front. Both meters would require the use of an arm to pick up meter pulses. The drop down sensors automatically align and reduce test time with the alignment process.
  • VESTA has an adjustable 16” snake arm sensor which can be used in lieu of any of the other sensors for meters such as the Itron™ Sentinel which has an infrared pulse on the front panel. This sensor can also be used on any other meter if the user finds it more desirable.
  • VESTA uses a specially designed Sentry 410 Optical port for testing meters through the optical port. The Sentry 410 can also be used for programing and resetting the meter by toggling to the manufacturers software. Both testing and programming/resetting can be accomplished without changing probes.
  • VESTA has an internal Windows 10 Professional Intel NUC computer with Intel Core i3 processor 4 GB RAM, 128 GB SS hard drive. Also has WiFi and is networkable. All rights transfer with the test board.
  • VESTA is completely programmable with features such as imbalanced loads which can be programmed to modify the voltage and current on each phase, repetitive testing where you can test the same meter an unlimited number of times. The user can change any variable such as voltage, current, Ke, frequency number of revolutions, etc all with their finger.
  • VESTA has a data export function which allows the user to create their own csv or comma delimited file, selecting only the values which are necessary. No dependency on Vision Metering to create custom files.
  • VESTA ships complete with a Bar Code Scanner, wireless keyboard and mouse, all sensor pick ups, Sentry 410 optical probe and an arm for testing mechanical meters.
  • VESTA has a 2 year warranty on the test board and a 10 year warranty on the internal standard.

Some of the Nation’s Largest Electric Utilities Depend on Vision Metering for their Meter Shop Services. We offer:

Most meters are time run before entering the meter shop’s retrofitting and testing areas which ensures a properly functioning meter prior to retrofit.

It also provides an individual assessment of possible tampering and ensures every meter returned to the customer is fit for service.

Our metering professionals visually inspect each meter’s gear mesh and disk for irregularities, deformities or tampering and install a potential link if one is necessary.

The time run board determines a meter’s eligibility for retrofitting or testing.

Installation of an Automatic Meter Reading module is a process called “retrofitting” where a module is installed on meters that have been pulled from field service mid-life and returned with an AMR-fitted system.

Through professional partnerships, Vision Metering is able to provide modules manufactured by DCSI, Itron Comverge, Ramar, Hunt Technologies and others.

Our sales managers are well-versed in the benefits of each brand and will help you find the best system for your meter reading needs.

In the retrofit stage each meter has its name plate removed, its disk cleaned with an alcohol swab and marker applied which will allow the module to read rotations.

Each brand of module has its unique installation process. Our retrofit professionals are thoroughly trained on each available module.

We rely on the unique design of our Sentry 7000 Meter Base Washer to ensure tough bristles and clean water do the work of scrubbing each base.

The cover and meter are separated after the base is washed.

Each cover goes through an industrial dishwasher that uses high pressure, heat and industrial cleaning fluid, leaving the glass or polycarbonate clean and clear.

Our Receiving Station generates bar codes for each meter in accordance with the customer’s specific requirements.

The bar codes are printed on mylar labels and applied directly to the meter’s name plate.

The barcode allows the meter to be tracked through every process in the meter shop and provides for easy tracking once shipped to the customer.

Meter testing is the most important function in our meter shops today.

Our VESTA test boards… and our meter testing professionals… ensure every meter performs within standards set by our customer.

Process requirements are published per project and contain information such as acceptable meters, acceptable registers, test adjustments and specific details designated by each Utility.

The process publication is available for review and approval of each customer. Test data is collected by Power Track Meter Shop Software throughout each process.

Our in-house Software Engineers ensure test data is formatted to a customer’s specifications and has the ability to present test results in whatever format a customer requests.

Once the meter is tested and cleared, the module is programmed in a process which takes anywhere from 5 to 12 seconds.

Using a Read One Pro, the programmers prepare the module to perform as designed to work in the field.

Meters undergo their final inspection in the Boxing area. Each meter is checked to ensure that every meter is without defects and registers are set to “0”.

Meters ready for shipping are packaged per customer specification. Each meter is scanned to flag the database that the meter is leaving the meter shop and is eligible to be added to the data file.

Pallets are stacked carefully and stabilized with shrink wrap to ensure safe delivery.
