DENT Instruments, a global leader in the design and manufacture of power and energy measurement instruments, announced that the PowerScout 24 meter is now available as an Ethernet device.
The PowerScout 24 Ethernet communicates using Modbus TCP or BACnet IP over Ethernet instead of an RS-485 connection. Ethernet networks have several advantages over RS-485 networks including faster meter response times, improved remote access, and the ability to support more PowerScout devices on a single network. Additionally, the ability to use existing Ethernet infrastructure means there is no need to install a separate network.
Christopher Dent, President of DENT Instruments said, “We are very excited about the addition of Ethernet capability to the multi-channel PowerScout 24. This optional feature enhances the capabilities of the PowerScout 24 and we are certain that clients will find the Ethernet communications helpful when adding the meter to their existing network.
The PowerScout 24 offers the lowest-cost per meter point versus comparable industrial multi-channel power meters. The modular design of the PowerScout 24 allows it to be configured for monitoring multiple electrical circuits or for current-only monitoring of branch circuits. There are virtually no restrictions in “mixing & matching” current transformers on the PowerScout 24 and any combination of CTs can be used.
DENT Instruments is a leading supplier of an array of precision measurement instrumentation and analytical software in the field of energy management.

DENT Instruments is pleased to announce that the much-anticipated PowerScout 12 HD is in stock and ready to ship! We’ve combined the most popular, standard features with smart, new options to create the most powerful submeter on the market today. See what makes the PowerScout 12 HD an exceptional addition to your metering toolkit.Smarter, Faster Multi-Circuit Installations with the PowerScout 12 HD
The ideal size for projects large and small, the PowerScout 12 HD is designed to monitor multiple independent loads on a single meter. Lower installation and commissioning costs while benefiting from revenue-grade accuracy in a wide variety of large building environments including multi-tenant residential, commercial, industrial, retail, and more.
Facility management professionals and specifiers will appreciate that all PowerScout HD meters are equipped with smart, standard features like the flexibility to switch between Modbus®orBACnet®, Ethernet or Serial (RS-485), or the ability to use any millivolt CT, including Rogowskicoils, on any channel. When installed, the platform agnostic PowerScout HD Series meter easily integrates within connected products of any building management system (BMS) software, models equipped withBACnet®andModbus®protocols and can be easily utilized with any system. The PowerScout 12 HD is available in a rugged enclosure or as a circuit board on a handy mounting plate. With the launch of this product, we are also introducing a number of features that are brand new to the HD platform. Learn more about how these features will simplify your installation and reduce costs on your next project. New Feature: Alarms Our most requested feature is now available: Alarms are standard on the PowerScout 12 HD meter. Alarms can be set through ViewPoint HD software to be triggered by voltage and/or current over/under events. The persistence setting is adjustable within the software. Quickly identify equipment that is not operating properly so that it can be repaired or replaced before damaging other systems. Specifications:Electromechanical relay, 50 VDC, 500mA [VIDEO]See a demonstration of the Alarms function in ViewPoint HD here. New Feature: Interval Data Recording & Real Time Clock The PowerScout 12 HD now features interval data recording of kWh. The meter’s non-volatile memory stores up to 60 days of 15-minute kWh data that can be downloaded in the event of lost communication with the RTU. The CSV data file can be quickly downloaded through a direct USB or Ethernet connection using ViewPoint HD software and used to backfill any missing data. This feature works automatically in the background – no configuration necessary. In addition, the PowerScout 12 HD has a new, capacitor-backed real-time clock that is used to ensure an accurate time-stamp on all recorded data. Unlike other systems, there is no battery to change and the capacitor provides the RTC power for up to 1 week. The clock can by synchronized with the PC clock during meter setup. New Feature: Pulse Inputs No need for additional pulse counting equipment – collect pulses and metered energy data all with one piece of equipment. Monitor a variety of systems using the standard pulse inputs. Configure each of the four input channels independently with customizable units of measure (i.e., gallons) within ViewPoint HD Software. Specifications: Dry contact (Form A), 10 Hz Max input, 3V, 1mA, Floating Point Scaling Learn more about the Pulse Input feature in the Manual. New Feature: Easy Meter Connection & Configuration Setting the PowerScout HD up for a new deployment has never been easier thanks to these new features. Network Scan Using ViewPoint HD Software, you can now quickly scan the local area network and find all the PowerScout HD meters installed on the network. The results page shows each meter’s system description and even allows for some basic meter setup directly from the scan window. Use ViewPoint HD to give each meter a “friendly” name, such as “3rd Floor Utility Rm,” to identify the right meter even faster. Pre-Configuration Maybe you have several meters that need to be configured the same way. Or, maybe you don’t have the meter in your possession, but need to configure it ahead of time for an installer. It is now possible to build a meter configuration file without having a meter connected. This is especially helpful for teams who handle configuration and installation in two separate steps. Mounting Plate Similar to the PowerScout 48 HD, the PowerScout 12 HD will be available with a custom mounting plate to facilitate easy installation. The mounting plate features mounting holes that make installation quick and painless. The mounting plate also reduces the board from flexing during installation. Note the HV cover is only available with enclosure models. Security PIN[VIDEO]PowerScout HD meters have two levels of PIN protection that users can choose to assign for restricting access to meter information. Enable either a “read-only” or “read/write” PIN for enhanced meter security. Learn more about enabling a security PIN in this video. PowerScout vs PowerScout HD: Modbus Register/BACnet Objects The Modus register and BACnet Objects schemes are different between the PowerScout 3037/24 and PSHD meters. The PSHD meters now report all data in floating point format which requires less manipulation (such as scaling) by the host RTU. Register organization has been improved by adopting the SunSpec three phase net metering model as a basis. The PSHD register/object list is available as an Excel® document (click here to download). The PowerScout 3037/24 and PSHD register space is non-overlapping so that both meter types can exist within the same network allowing for expansion with minimal disruption of existing scripts and programs. BACnet object types in PSHD have been updated to include all the Standard Objects in BACnet version 135-2016 including organization of elements through Structured View. To learn more about migrating from the PowerScout 24 to the PowerScout HD Series, see our Migration Guide.[VIDEO]Learn some tips & tricks for using the Register List spreadsheet here.

A team of four Seattle City Light (SCL) employees have recovered $1.5 million in just two years using equipment purchased from DENT Instruments. Large-scale construction is booming in Seattle and has been for many years, but Seattle City Light was unable to efficiently capture electrical usage and bill accordingly as multi-unit skyscrapers were taking shape — that is, until the initial purchase of 12 ELITEpro XC meters from DENT Instruments in 2014. Electrical meters are one of the last items trimmed out in construction, but things can’t be built without electricity. So, even though projects weren’t ready for SCL-supplied meters to be installed, Seattle City Light would routinely energize the vault to support construction. Engineers would shunt the meter sockets, allowing unmetered energy to flow to individual units. This provided electricity to power such things as drywall heaters and other tools. In the meantime, Seattle City Light was losing millions of dollars in revenue. They didn’t know exactly how much until Matthew Blouch, Tech Meter Crew Chief, sampled several projects around Seattle and documented detailed losses. Blouch knew Seattle City Light was losing money, but was surprised to learn how much. “After that, I had a vision of capturing that revenue,” Blouch said. “I could see the solution, but I needed to find the tools to make it happen.” The first thing he considered was to install solid core current transformers and a meter into large-scale construction projects, but that would be too costly and not every efficient. “So, I started Googling for alternative solutions and I found DENT Instruments.” As Blouch read on DENT’s website www.dentinstruments.com), “The ELITEpro XC energy data logger is a complete, portable solution for pinpointing electric usage and recording building performance metrics. It is capable of measuring, storing, and analyzing electrical consumption data that is derived from the voltage and current inputs.” Combined with theRōCoil (Rogowski) current transformers(designed for large loads or large cables and bussbars), Blouch knew the DENT Instrument products could be the interim solution between a flow of free electricity during construction and individually metered occupied units. It was also important that the operation of the tools was easy to learn as each of the crewmembers aren’t specialists; instead, they are expected to cover all job functions interchangeably. The ELITEpro XC and RōCoils fit the bill. According to Blouch, installing the meters is easy, the RōCoils flex nicely, and downloading the data is intuitive and straightforward. “And we really love the accumulative running kWh display for Power Channel 5 [in ELOG software].” The next step was to work with contractors to sign an agreement to participate in SCL’s Temporary Totalized Metering (TTM) program. Blouch explained, “It basically states that SCL will meter the entire construction load and bill [them] for the unmetered unit power.” While one might expect the contractors to oppose metered billing during construction because of the additional costs, they actually find it to be beneficial as they can schedule their projects more efficiently, Blouch explained.
Now, Seattle City Light has 32 ELITEpro XC instruments deployed throughout its service area and the Current Diversion and Revenue Recovery program is recovering approximately $500,000 a year for the utility. “It was a real ‘aha moment’ when $20,000 to $30,000-a-month invoices were being generated for the large-scale projects,” said Blouch. Seattle City Light has realized other benefits as well. “Efficiency and safety have increased significantly,” Blouch said. Now that they’re metering projects from the beginning, the crew doesn’t have to rush to jobs when a certain window opens to install a meter. In addition, the crew isn’t required to operate within construction zones as often. “We don’t have to climb over dangerous equipment, squeeze around framing at high heights, and be exposed to silica and drywall dust,” he said. Overall, Blouch is very pleased with the products and the customer service he has received from DENT Instruments. “This is not a traditional use for the ELITEpro XC,” said Blouch, “so we had to spend some time working DENT staff to smooth out the application. In addition, Christopher Dent himself came to work with us on the implementation and train us on the technology.” “The potential for revenue recovery is huge if SCL had the resources to install the TTM program at every large-scale construction project in the city,” Blouch concluded. And, while other utilities haven’t yet asked about SCL’s TTM program, Blouch expects they will once the SCL experience with the ELITEpro XC and RōCoils is shared more broadly.
