dent instruments

The ELITEpro XC is a complete solution for pinpointing electric usage and recording building performance metrics. It is capable of measuring, storing, and analyzing electrical consumption data which is derived from the voltage and current inputs. The ELITEpro XC uses direct connections to each phase of the voltage and various interchangeable CT options such as split-core current transformers, or flexible RōCoils (for large loads or large cables and buss bars) to monitor current on each phase.

Submeters Help Avoid Increased Maintenance Fees

Located a few blocks from Pittsburgh’s Carnegie-Mellon University, Park Plaza Condominiums, a nine-level mixed-use property, is home to various commercial offices including Park Plaza Condominium Associates, the building owner.

Problem

Pressured by rising costs, the property manager—Arnheim & Neely—was faced with raising monthly fees to offset the property’s $20,000 per month electric bill or find a way to allocate and bill each owner’s electrical usage to recover a significant percentage of the facility’s operational overhead. Seeking to work with the owners, some of whom had been in the building up to 30 years, Park Plaza Condominium Associates chose the latter option.

Solution

A&N estimated running additional power company metering to each of the building’s more than 120 units would be five or six times costlier than simply submetering each apartment, including all residential units, to isolate each owner’s electrical usage (kWh) behind the main utility meter.

Submetering turned out to be the ideal solution for this application and a great way to avoid the inherent unfairness of traditional ratio-based fees commonly used in the industry. Based on a simple cost-per-square-foot formula, ratio-based structures favor high-consumption users by unfairly saddling low-use consumers with shared costs beyond their control or ability to manage. Submeters prevent such inequities and eliminate disputes by providing proof of actual energy usage.

At this point, the electrical contracting firm, Scalise Industries, Lawrence, Pa., was called. As service manager of the electrical division, Phil Reiss was given the job of managing the project, finding a vendor and supervising the submetering installation. Based on prior experience with the E-Mon D-Mon submeters, Reiss worked out the details with his local distributor, Tony Rinehart of Scott Electric, and the local E-Mon rep, Jack Group.

Once the job got underway, the team of manufacturer’s rep, distributor and project manager functioned like a well-oiled machine. “Scott Electric didn’t have an order that size in stock,” Reiss explains. “However, the factory got us all the equipment in a very timely fashion. E-Mon’s tech support and Mr. Jack Group were a huge help.”

INTRODUCTION

Wireless sensor devices connect sensors wirelessly among each other as well as to monitoring and management setups. This report forecasts the market size of wireless sensors for the years 2012-2019. This report is an update of the one published in 2011. The wireless sensor landscape is characterized by diversity on the following fronts:

– The parameter being sensed.

– The end-vertical application.

– Wireless technology adopted.

Consequently, the market for wireless sensors is fragmented and disorganized. This report straddles this diversity and presents a consolidated picture of the market. Since

the publication of the last report, wireless sensors continue to make new headways, but are unable to bite the bullet when it comes to consolidation among diverse wireless

technologies. This failure has resulted in an adverse impact on the growth rate, which nevertheless remains attractive. While the sensing principles of wireless sensors are consistent with that of wireline sensors, wireless sensors have the challenge of operating with an attractive form and with robust power management. The payout is spectacular. In most cases, wireless sensors beat their wireline counterparts hands down in the following aspects:

– Physical reach.

– Time to roll out and install.

– Pricing.

– Suitability in harsh operating environments.

Wireless sensor devices are the actual sensing elements that are present in the wireless sensor networks. They do not include gateways or management software. This report deals exclusively with wireless technologies employed in the personal area network (PAN) and local area network (LAN) topologies. It does not cover wide area networks (e.g., commercial cellular networks).
