ARTIQ 144 is an extremely precise meter and analyser for remote monitoring of energy consumption and power quality parameters in submetering and smart metering applications. The DIN rail mountable display-less design with multiple communication options is suitable for a wide spectrum of automation tasks in industrial applications, modern buildings, remote supervison of the infrastructure and also for the energy management.

Its input, output and communication interface portfolio can be optionally extended with additional modules for extra functionality. Currently a 10/100 MBit Ethernet, USB, M-Bus and wireless(ZigBee, WiFi) extensions are available.

This compact instrument is an ideal high-end source of data for modern SCADA systems with embedded support for Modbus and M-Bus protocol. Etehernet versiion also prowides webserver with actual data. It is also supported by the ENVIS application.

In complex systems the instrument can be well integrated with other instruments - namely with the PA 144 and SMD 118.

ARTIQ 144: measures and evaluates the electric parameters such as frequency, voltages, currents, active and reactive powers, energies and power quality indicators. It records minimum, average , maximum values, and periodic energy meter readings. It evaluates and records voltage events and other disturbances on the supply voltage and other power quality parameters. Archived measurements can be processed in ENVIS application.

Typical wiring and mechanical dimensions

Typical connection schema for SMC 144 and its mechanical dimensions

Wiring example: Currents of 5A up to 600A are measured directly with clamp-on or wire-through probes, this special approach significantly reduces the total cost of installation.

ENVIS application suite provides all features for basic instrument management (configuration, supervision, fw update). It also downloads and archives data from all the supported instruments. import/export, data analysis and advanced reporting of the records is also provided. ENVIS is available free of charge to be used with all our instruments.

Typická instalace aplikace ENVIS

ENVIS.Online system service can be used to implement complex power quality monitoring and/or energy efficienci control and monitoring systems. By using email,  SMS or SNMP all registered users and administrators can be warned upon exeptional situations, malfunction of supply or monitored instruments or it can be used to post periodical analysis/reports.

Additional plugin modules can also add special features or customizations to booth ENVIS and ENVIS.Online in a modular manner. 

Typical installation of ENVIS


Optional firmware modules

Voltage and power event cycle data logger module.
  • Ripple Control (Mains) Signals - RCS Module: for measurement, recording and analysis of a ripple control signal. Several formats of the telegram are also supported for decoding.
  • Voltage Events - VE Module: for recording and evaluation of voltage events (SMVQ & SMPQ does include this feature in its default configuration).
  • General Oscillograms - GO module: for detection and precise recording of various waveform distortions. This module records the so called oscillograms of voltages and currents in extended detail, capacity and trigger options into the flash memory.
  • Modbus Master - MM module: in supported instruments with memory it activates new option to record Modbus data from connected slave devices. It can work as a datalogger to NOVAR PFCs as well as to local sub-meters or other Modbus sensors.
  • See: other built-in meters and analysers, portable analysers and data loggers, ENVIS 1.1 for data analysis.
