DENT Instruments Metering Overview

DENT Instruments Metering Overview

DENT Instruments supplies a wide range of metering solutions ranging from portable meters and loggers for M&V projects, single meters for three-phase loads, multi-circuit meters for high density three or single-phase loads and a SMARTlogger for monitoring and gathering data for projects. Along with meters, DENT provides a family of CT (Current Transformers) including split-core, clamp-on and Rogowski coil “rope” CTs (RoCoil™).

Common key functionality

  • BACNET and Modbus support for permanent metering systems (PowerScout meters) that communicate with existing BMS systems
  • .333v inputs in the ELITEpro & PowerScout meters
  • Software available to support installation of the meter

Temporary measurement tool

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.

Smart Logger

SMARTloggers

 

The SMARTlogger series of instruments are designed to monitor the on-off status and total time of use data. SMARTloggers provide the operating schedule for energy-consuming devices or systems. Models are available for lighting systems, motor loads, or virtually any electric load generating at least .25 amps. Professional installation is not required to use these small, robust loggers.

Performance summary

Strengths:

  • High resolution 5 amp slit core CT that converts the 5 amp to .333mv input (despite no 5 amp input meter) which allows easy adaption to the older 5 amp configuration meter installations in the field
  • Multiple solutions for customers to choose from
  • Configuration software for easy setups; Preconfigured using a USB input
  • Line powered equipment. No auxiliary power required. (Does not apply to the SMARTloggers, which are battery powered – user-changeable coin-cell battery)
  • Wifi and Bluetooth connectivity options for temporary metering (ELITEpro XC)

Weaknesses:

  • Limited to .333v CT inputs
  • May be buying meters (with no CTs) that may never be implemented, but will still be available for future use. Ex: Requirement to meter 5 three phase panels and having 8 in the box
  • No harmonic measurement capability
  • PowerScout series: local display is optional on the standalone meter and not available on the multi-circuit meter. Note: Data can be locally displayed via Bluetooth to phone application or using DENT software to the meter USB connection
