European MID certifies Carlo Gavazzi meters

Carlo Gavazzi has obtained certification stating that its range of meters complies with the requirements of the European Measuring Instruments Directive (MID).

The MID's Annex B and Annex F certification involve type-approval from notified bodies and verification by authorised laboratories.

The first level of certification, also called the 'EC type certificate', confirms that the meters meet stated MID accuracy, climatic conditions and mechanical and electromagnetic environments (Annex B).

This certification is normally requested for sub-metering systems in industrial or service industries.

The second level is the individual certification, which can be required for main metering in the domestic market.

Carlo Gavazzi meters are tested by Physikalisch-Technische Bundesanstalt (PTB), Germany's national metrology institute.

Carlo Gavazzi's MID-certified range includes an ultra-compact DIN-rail mounted single-phase 32A energy meter and three-phase 65A energy analysers offering built-in hot/cold water, gas and remote heating measurements and load monitoring.

The EM11-DIN is a compact 1-DIN module that adds MID-certified power measurement and control functions to active energy metering.

It is a single-phase energy analyser with built-in configuration push-button and LCD data display.

It provides active and reactive energy metering together with cost-allocation functions.

The EM21-72D is a compact three-phase energy meter that features a multi-application detachable display and dual mounting technology.

It can be used as a basic energy meter or multifunction meter and brings simplicity and compactness to building-management systems and cost-allocation applications.

The EM26-96 1-2-3 Phase energy analysers feature a built-in configuration joystick and LCD data display.

They have a range of system and single-phase variable measurements, along with utility metering (energy, hot/cold water, gas, remote heating) and load monitoring with harmonic analysis up to the 15th harmonic.

They are particularly suitable for import and export energy metering and for cost-allocation applications.

All of the solutions meet category-MI003 standards for climatic conditions, corresponding to a temperature range from -25 to +55C.

Appropriate mechanical environments are covered by category M2, applicable to instruments used in locations with significant or high levels of vibration and shock.

The MID defines categories of electromagnetic environment, the most relevant one being E2, which covers locations with electromagnetic disturbances corresponding to those likely to be found in other industrial buildings.
