Fuji Electric's stand-alone M5000 electromagnetic flowmeter is designed for accurate and reliable measurement of conductive fluids. This type of flowmeter introduces the concept of the electromagnetic flowmeter, presenting its fundamental operating principles and its use for accurate measurement of conductive fluids. Its autonomy and advanced technology make it the ideal tool for optimized plant management, even in the most demanding environments.
Operation of the M5000 electromagnetic flowmeter is based on Faraday's law, which states that the voltage induced in a conductor moving through an electromagnetic field is proportional to its speed.
Excellent repeatability combined with long battery life make this innovative water meter an indispensable flow measurement device for the water market. The magnetic field is used to measure flow by generating a voltage proportional to fluid velocity.
Typical applications include leak detection in water networks, water consumption measurements and irrigation plant management. The flowmeter measures conductive fluids, enabling high accuracy under a wide range of conditions.
This flow meter is recommended for all installations without an external power supply, where it is necessary to know precisely the flow of a liquid and the consumption of water.
The M5000 electromagnetic flow meter can also be used with an available power supply. The meter can be powered with mains voltage and in case of a mains failure, it is powered by an internal battery. Important data are therefore saved.
The M5000 electromagnetic flow meter with converter has been designed for harsh environmental measurement conditions. The meter has no moving parts and can be used to measure water containing particles like sand or gravel.
The M5000 electromagnetic flow meter features IP67 housing (IP68 optional), making it a reliable meter even when submerged.
The converter is equipped as standard with an internal data logging function, which can then be read out via infrared or RS232C links using the ModBus® RTU communication protocol. The collected data can also be retrieved via radio frequency or GSM/GPRS. The data can thus be centrally compiled and evaluated.
A portable console enables the M5000 flow meter to be checked during operation without interrupting the flow.
Exceptional autonomy
Powered by internal 3.6V lithium batteries, this flowmeter offers an impressive 6 years' autonomy, extendable to 12 years as an option. For maximum continuity, a management board allows toggling between the internal batteries and an optional external (AC) source, ensuring uninterrupted operation even in the most demanding conditions.
Variable diameters and user-friendly display
Available in a range of sizes and diameters from DN 15 to DN 600, with PTFE or hard rubber linings, this flowmeter is suitable for a variety of applications. The two-line LCD display offers a clear, intuitive user interface for easy programming via three front-panel keys.
Exceptional Accuracy and Unmatched Repeatability
With a measuring range from 0.03 to 12 m/s, this flowmeter guarantees outstanding accuracy. At speeds above 0.5 m/s, accuracy is better than ±0.4% of the measured flow value, while at lower speeds it reaches ±2.5 mm/s. Repeatability of 0.1% ensures reliable consistency under all conditions.
Advanced functions and versatile connectivity
The flowmeter offers a full range of logic outputs, including four open-collector outputs, passive 30 VDC/20 mA, max. 100 Hz. Logic output functions include min/max alarms, flow direction detection and error signalling. Serial connectivity via RS232 and ModBus® RTU, as well as an infrared link (IRDA), offers flexibility in integrating the flowmeter into larger systems.
Rugged and Ready for Extreme Conditions
Housed in a cast aluminum enclosure offering IP67 protection (with IP68 option), this flowmeter is designed to withstand the harshest industrial environments. Cable inputs are provided by two M20 connectors for power supply and outputs, while sensor cable inputs use two M20 connectors for signals to the sensors.
Adaptability and extended operating temperature
A remote mounting version offers maximum flexibility, with a range of up to 30 meters. The operating temperature range from -20°C to 60°C enables use in a variety of industrial contexts.
Sizes : DN 15 to 600 (1/2’’ …. 24’’)
Nominal pressure : PN 10 to PN 100
| Type | Diameter | Temperature Fluid |
|---|---|---|
| Hard rubber | DN 25 to 600 | 0 to 80°C |
| PTFE | DN 6 to 600 | -40 to +150°C |
Fuji Electric offers the option of recording measured data via a radio, GSM or WIFI link. The electromagnetic flowmeter (DEM) enables efficient data collection and transmission. The optional USB/HF key programming kit, including AVELOUR software, enables the link type to be adapted to site requirements.
Information can be recorded, displayed, evaluated and stored on a central server using suitable software. Password access management ensures the protection of recorded and downloaded data.
The flowmeter's design is based on the absence of moving parts, making it particularly reliable for measuring conductive fluids, especially water-based ones. The flowmeter can be adapted to a wide range of applications, from clean liquids to slurries.
Electromagnetic flowmeters are essential for measuring the flow of conductive fluids in various industrial applications.
