The MUT2300 sensors represent the state of the art of Euromag International production for water cycle and process applications. The innovative inner part of the sensor that increase considerably the liquid flow rate and the reading accuracy of signal generated to the electrodes, enables an extremely wide range of measurement. These performances allow to measure also low flow rates precisely and repeatable, even in difficult/problematic applications with solid parts. This flanged 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 on the lower side of the stainless steel AISI 304 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. With the aim of measuring such potential of very low values, the interior of the flow tube is electrically insulated, thus the process liquid is no longer in contact neither with the material of the flow tube nor with that of the flanges. The converter used generates the current supplying the coils, acquires the electrodes potential difference, process the signal to calculate the flowrate and manages all the communications. The entire sensor has an IP68 protection degree suitable for a permanent immersion in water up to a depth of 1.5m.
Body and Flanges
The flanges and the sensor external surface are acrylic painted. This treatment gives the sensor an excellent resistance to water and external agents even in permanent immersion or buried. The MUT2300 may be supplied in stainless steel, flanges included, or with a special paint ideal for application in C4 class environment (UNI EN ISO 12944-2).
The standard internal insulating lining is in Hard rubber (Ebonite) in compliance with WRAS, FDA and DM174 standards. The liquid temperature can reach 80°C. Thanks to its high resistance to scraping, the Ebonite is considered the best material for fluids containing scattered solids for applications of water treatment, residual water, potable water and irrigation.
The standard electrodes are in Hastelloy C and therefore this guarantees a wide compatibly with process fluids. If required, they may be supplied in Hastelloy B, Titanium, Tantalum and Platinum. A partially empty tube detection (fourth electrode) is installed and can be enabled or disabled through the software.
Coupling and Connection to the Sensor
MUT2300 sensors may be coupled with any Euromag converters. In the separate version the sensor is connected to the converter through a cable whose length depends on the liquid conductivity; the maximum length must not exceed 100 metres on the powered version and 30 metres on the battery version.
Neglectable Pressure Drop
The electromagnetic flowmeters do not have any moving internal parts, thus they have a very low pressure drop. The OIML R-49 permits a maximum pressure drop of 630 mbar at velocity of about 8 m/s. The MUT2300 flowmeters, thanks to its unique design, projected to accelerate the flow and amplify the signal to the electrodes, guarantees a pressure drop less than 250 mbar at velocity of 8 m/s. The pressure drop is always less than 10 mbar at velocities lower than 1 m/s.
Installation with No Upstream and Downstream Distances
The cone shaped section of the internal part of the sensor, allows an optimized and accelerated flow profile which permits to install the sensor in any kind of condition; no need to have straight sections/segments of pipes upstream and downstream. This U0-D0 condition enables to have an extreme flexibility on the flowmeter installation position.
