  • Designing Energy Meters with the PIC16F873A
    The deployment of electronic energy meters has gained a great deal of momentum over the past several years. This is due to their two main advantages over the traditional electromechanical designs: improved accuracy and an expanded set of features. Current microcontroller technology allows designers
  • Using the ECOLEC Series 100 Meters as a CT Operated Meter (.pdf)
    The ECOLEC Series 100 meters are specified as direct connected meters. They can however, in conjunction with external Current Transformers (CT's), be used as CT operated meters. The use of external CT's enables the meter to measure load currents well in excess of the meter's maximum current rating
  • How a Vortex Flow Meter Works
    Vortex flow meters are increasingly becoming the flow technology of choice for gas, liquid, and steam flow measurement. Vortex flow meters are ideal for measuring saturated and supersaturated steam in large facilities to improve steam production efficiency and allocation. Volumetric water flow
  • PIC18F2520 MCP3909 3-Phase Energy Meter Reference Design - Meter Test Results and Adapting the Meter Design for other Requirements
    for Calibration used for this Application Note the meter. Instead, the software allows Figure 2 describes the calibration and test setup used. user input of the true current and voltage The electrical power standard (Fluke 6100A) was at each calibration step. The correction configured to generate
  • Input Bias Current Compensation
    This Application Guide describes the sources of input bias current on a high sensitivity instruments such as a null meter, the impact input bias current can have on measurements and how the user compensates for input bias current to minimize its impact on measurements.
  • Current Transformer Measurements
    The Current Transformer (CT) is used to sense AC current in single-phase or three-phase mains circuits. The CT typically has a 1A or 5A AC secondary that connects to a current, power or energy meter. This allows the meter to be located away from the mains wiring. CTs are available in a variety
  • Using the ECOLEC Series 100 Dual and Three Phase Meters as Uniphase Meters (.pdf)
    The dual phase EC12x and three phase EC13x meters in the ECOLEC 100 Series have been designed to measure energy in dual phase three wire and three phase four wire systems respectively. These multiple phase meters can however be used to measure the consumption of loads that are all fed from the same
  • Metering, Visualisation and Analysis of Electrical Energy using Energy Meters with Modbus TCP Interface and Moneo RTM
    Companies are increasingly focusing on production-level energy monitoring to allow for more efficient, sustainable and forward-looking planning. Information about possible reactive currents can be used to implement suitable solutions for reactive power compensation and thus avoid unnecessary costs
