Crouzet's M3 Energy Expert: Energy Counting Solutions

Image4.jpg

Crouzet Automation presents a set of energy counting solutions for commercial or industrial buildings, machines and installations. Thanks to its highly visible display, Millenium 3 is the right solution to visualize and centralize multiple energy meters with pulse outputs.

Up to seven pulse inputs, coming from different kinds of metering equipment, (energy, water, calories, etc.) are treated to display monthly consumption. This consumption can be tracked with the memory of the previous month, the total by use and the sum of the total uses.

The M3 Energy Expert solution is a set of macros functions delivered with associated literature. These macro functions can be easily interconnected to build Energy Management applications using M3 Soft V3.0 AC8. They are compatible with all metering products with pulse outputs!

You can adapt the application: change the number/name of uses, adapt the parameters to the metering equipment (100 – 1000 – 50 – 500 Pulse/kWh), use relay outputs for alarms, and add some other automation functions.

Finder 7E Series Digital Meters Help Reduce Local Energy Consumption

Finder.jpg

Finder has announced a series of digital energy meters for accurately monitoring and measuring electricity consumption in plant and machinery, HVAC, lighting and other environmental control equipment.  The DIN rail mounted 7E Series provides users with local, high visibility 7-digit LCD display of total and partial kWh consumed, instantaneous power, voltage and current.

For single phase metering of currents up to 35A, the 7E.23 model is just 17.5mm wide and is operated by a single control key.  The 70mm wide, two control key 7E.46 and 7E.56 meters serve 3-phase applications; the 7E.46 handling currents up to 65A and both day and night tariffs, and the nominal 5A 7E.56 is usable with suitable current transformers for measuring up to 1.5kA.

To support remote energy management via a centralised BMS, these digital meters also provide a pulsed, open collector interface to the DIN43864 standard.  The 3-phase models also provide an error display indicating either missing phase or incorrect current direction.

The 7E Series digital energy meters meet the 1/B accuracy class and protection class II and comply with EN62053-21 and EN50470 norms.  They can be conveniently mounted in existing consumer units and protected by a tamper-proof cover with a lead seal, provided as a separate accessory.

FINDER Extends Range of Instruments for Energy Consumption Monitoring

Finder.jpg

New to the Finder range of energy consumption meters is the three-phase 7E.36 Series, which includes single and dual-tariff kWh models for the measurement, recording and display of power consumption in individual sub-circuits at current levels up to 65A.

The meters are particularly applicable where there is a statutory need for compliance with the EU Measuring Instrument Directive (MID) 2004/22/EG which comes into force in October 2006. The current pressure to reduce energy consumption is also driving the need for accurate monitoring and measurement in specific areas.

The 7E.36 Series meters provide a compact, accurate and easily-installed solution to metering three-phase energy consumption, and are ideally suited for use by manufacturers and installers of machinery and equipment, control systems manufacturers, contractors, site service engineers and designers of building management systems (BMS). Typical areas of use include industrial and commercial installations, test cells, machines, control cabinets and switchboards.

Type 7E.36.8.400.0000 is a single-tariff 3-phase meter, and Type 7E.36.8.400.0002 is a dual-tariff version for use with standard and economy tariff supplies. Both meters are specified for a maximum current rating of 65A, and are housed in a compact 70mm wide enclosure that can be surface mounted or fitted to a 35mm DIN rail, allowing them to be installed in confined spaces or mounted on standard sub distribution boards.

The meters feature 4mm high, 7-digit display(s) including a red decimal digit, to provide an easy-to-read display with a maximum totalising count of 999,999.9kWh. A high resolution pulsed open-collector output to DIN 43864 provides a link to BMS or other types of remote monitoring system. A variable rate pulsed red LED indicator offers a rapid visual indication when abnormal operation is occurring, for example due to phase loss or inversion. Terminal covers are also available to enable a tamper-proof seal to be fitted.

The 7E.36 Series is compliant with EN 62053-21 and prEN 50470 as well as with the EU MID 2004/22/EG, and is certified by PTB (Physikalisch-Technischen Bundesanstalt). Accuracy is specified to Class B and protection to Class II.

Finder Introduces Meters for Individual Monitoring of Energy Consumption

 Finder.jpg

The 7E Series single phase kWh totalising meters from Finder have been designed for the measurement, recording and display of individual energy consumption for loads drawing up to a maximum of 65A.

 FIN0033_7ESeries.jpg

 

The meters are targeted at applications in residential, commercial and industrial  installations where the consumption of energy needs to be measured or monitored.  This might be either to assist in meeting government targets for reduced emissions by minimising energy consumption, or to allow metering of locally billed electricity supplies. Typical areas of use might include test laboratories, the individual monitoring of machines, control cabinets and switchboards, in battery charging equipment, or for hook-up supplies to campers, caravans and boats.

The meters can be DIN rail mounted, and can easily be installed in a standard consumer unit. A high resolution pulsed open-collector output allows accurate remote monitoring.

The two models in the series, the 7E.13 and 7E.16, are rated for maximum current levels of 32A and 65A respectively, for a supply voltage of 230V AC at 50Hz. The display counter features a 4mm high, 7-digit display with a red decimal digit, giving a maximum totalising count of 999,999.9kWh. Both models have a maximum resolution of 100Wh, and their accuracy is specified as Class 1 (±1%). Rated power is 8VA and the AC operating range is 0.8 – 1.15 of nominal voltage.

The meters are housed in compact industry-standard packages with simple direct wiring connections. They are PTB approved in accordance with EN 61036, and carry CE type approval for EMC.

Model 7E.13 is a single unit width (17.5mm) with the digits arranged vertically, while 7E.16 is double unit width (35mm) and has a horizontal digital display. Both models feature a flashing red LED as a quick visual indication of operational status.
