Bermad - Model M10 - Electromagnetic Flow Meter

M10 is an electromagnetic flow meter grooved sensor that covers all diameters from DN50 to DN100. When high accuracy, lightweight, and compact dimensions are required, the choice of sensors cannot be other than M10.
These performances allow us to measure low flow rates precisely and repeatably, even in difficult/ problematic applications with solid parts.
The M10 sensor series bases its operation on the Faraday Principle, by which a conductor crossing a magnetic field generates an electrical potential perpendicular to the field itself. On the top and the lower side of the composite flow tube, two coils are installed; the magnetic field generated by the electric current crossing the coils induces in the electrodes a potential difference proportional to the flow rate.
The integrated battery-powered converter generates the current supplying the coils, acquires the electrode's potential difference, processes the signal to calculate the flow rate, and manages all communications. The entire sensor has an IP68 protection degree suitable for permanent immersion in water up to a depth of 1.5m.

A Revolutionary Perspective of the Flow Metering

The M10 is a battery-powered and 12VDC electromagnetic flow meter for use in agriculture, irrigation, district metering areas (DMA), water abstraction, custody transfer measurement of potable water (MI-001, OIML R49), and many other applications. Unlike other water meters, the M10 is a maintenance-free meter, offering a much wider range of flow, in a compact version. Thanks to the optimized flow profile, the M10 can be installed virtually anywhere without straight inlet or outlet runs, behind pipe bends, slide valves, or a reduction in the pipe. Its measuring tube is specifically designed to enable a stable measurement even at the lowest flow rates.

Made out of highly reinforced polyamide, the meter is the perfect solution for leak detection and pressure management systems. The highly robust and lightweight structure allows IP68 installations by the manufacturer's guidelines.

Victualic OGS process connections make the flow meter compatible with almost all installations, and adapting flanges of all types and standards are also available. Easy and quick to install, users will find this flow meter the perfect solution compared not only to mechanical meters but to any other non-moving parts flowmeters.

The inbuilt logger functionality provides total flexibility - enabling data to be interrogated in precise detail through the smart and user-friendly Mag-Net app, available on Apple and Google Play Store.

Body and Flanges

The M10 has a flow tube made from composite material. It is equipped with an integrated converter. The degree of protection is IP68. It may be installed between flanges up to PN 16 or ANSI 150. The sensor is grooved and can easily fit into all types of end connections with the preferred adaptor.

Internal Lining

The sensor body is in composite, thus the temperature of the liquid to be measured has to be between 0°C and + 80°C.

Electrodes and Grounding

The M10 has three electrodes in AISI 316L and, on request, they can be supplied in other materials. It should be noted that if the sensor is installed in metal pipe line, the liquid grounding does not require the use of grounding rings, because of the presence of the third electrode.

Calibration and Maximum Error

Each sensor is calibrated on a hydraulic test rig equipped with a ISO17025 traceable weighing system. The accuracy is equal to 0.2% ± 2mm/s. The repeatability of the measure is about 0.1%. Bi-directional measure. On request, the M10 can be supplied with certified MID OIML R49 for custody transfer.
