2 Sensors MUT 22 EL / MUT EL MUT 22 EL / MUT EL sensors represent the state of the art of EUROMAG ITERATIOAL production for water cycle and process applications. The new structure for the generation of the magnetic field, the innovative route of the signal generated by the electrodes, provide a sensor with an extremely wide measurement range: EL= Extended Linearity. This new sensors series follows the successful tradition of the MUT 22 / MUT, introducing a measurement range of more than 1:1 without linearization software. These kinds of performances allow very accurate measures on a wide flow rate range and to count lower flow rates that, before, would have been reset because of the effect of the converters cut off. This flanged sensors series bases its operation on the Faraday Principle, by which a conductor crossing a magnetic field generates a potential perpendicularly orientated to the same field. In this case the flow tube made in stainless steel AISI 3 is equipped with carbon or stainless steel flanges, two coils are installed on the top and inferior part; the magnetic field, generated by the electric current crossing the coil, induces in the electrodes a difference in the potential 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 flange.the converter used generates the current supplying the coil, acquires the electrodes difference of potential, process the signal to calculate the flowrate and administers the communication with the exterior. The entire sensor, when installed in the separate version, has a degree of protection IP 6 suitable for a permanent immersion in water up to a depth of 1.5m thanks to a welded plate structure containing the coil and the electrodes. 1. Body and flange. Coupling and connecting to sensor The flange and the sensor external surface are acrylic painted. This treatment gives the sensor an excellent resistance to water, even in permanent immersion. When special ambient conditions require it, the MUT 2 EL / MUT EL may be supplied in stainless steel, flange included (see Table 2). 2. Internal lining MUT 22 EL / MUT EL sensors may be coupled with any EUROMAG converters (see Table 5). In the separate version the sensor is connected to the converter by means of a cable whose length depends on the liquid conductivity; the maximum length not exceeding 1 metres as shown in Figure 1. If these sensors are inserted in a plastic or lined pipe line, they require the use of two grounding rings of the liquid, which are inserted between the flange and the counter flange or the installation of the grounding electrode. An empty pipe device is also available. The standard internal insulating lining is in PTFE for diameters from D 15 to D 5, in hard rubber (ebonite for food) for diameters of more than D 5. On request, the sensors may be supplied coated with PTFE with diameters of more than D 5. The temperature of the liquid to be measured is limited by the kind of internal lining used. (see Table ). 3. Electrodes 5. Choice of diameter When choosing the diameter we advice keeping at the full scale flow rate, a liquid velocity of at least 2 3 m/s. The maximum acceptable velocity is of 1 m/s. Figure 3 provides the flow rate for each D (nominal diameter) according to the liquid velocity. The standard electrodes are in astelloy C and, therefore, guarantee a wide compatibility with the process liquids, if required, they may be supplied in the materials shown in Table 3. 2/1

3 6. Maximum temperature of the liquid Maximum length of cables according to the liquid conductivity In the separate version the maximum liquid temperature allowed is shown in Table. In the compact version instead, the maximum 1 temperature allowed depends on the ambient temperature. This is due to the required cooling of the electronics. The maximum liquid temperature allowed for the compact version should be ºC. Maximum length of cables (m) Calibration and maximum error Conductivity ( us/cm ) figure 1 MUT 22 EL / MUT EL sensors belong to the reference Group B1 (ISO 131). Each sensor is calibrated by a hydraulic bench equipped with a reference weighting system and SIT certified. The uncertainty of the measure is equal to.2% of the read flowrate value when the velocity of the liquid is more than.2 m/s.

17 TYPICAL APPLICATIOS Billing consumption District measurements Transport lines Residual water treatment systems Irrigation The MC 6 converter has been designed with the purpose of meeting all the requirements of modern water management systems. It supports extended functions which make it perfectly suitable for measuring and billing in civil, industrial and agricultural sector and for flow measurement in residual water treatment. On board batteries in 6-B version guarantee at least 6 years operation under the reference conditions of use, and will maintain a useful life of 1 years from shipment. Connectivity is ensured by serial interfaces, both IrCOM and MODBUS RTU on RS 5. Communications may be implemented by using the DATAFLOW TX module via GSM and GPRS, bringing measurement and required data to the operator desk without the need for any remote action. The new generation converter extends the use of electromagnetic flowmeters to water distribution network, allowing a better control of flows in every point of installation. Even small flow rates can be monitored and consequently the status of leaks in the distribution network. For billing applications, it is an economical solution in terms of capital expenditure and operating cost. Installations in irrigation systems guarantee that each farmer pays for the water used, and allow optimization of water management. This converter is ideal for installation in remote areas, thanks to battery powering and sturdy and strong structure. Converter performance has been developed to meet the need to measure even small flow rates with maximum accuracy. It is therefore ideal for use in leak detection campaigns due to battery power and ease of communication through DATAFLOW TX. 3
