Name: Microwave Solid Flow Meter – Explosion-proof model for gases and powders: MF3000 Overview: The German company MuTec was founded in 1970 and now has a history of over 40 years. Located in Hamburg, a major city in Germany, MuTec has long been committed to innovation and development in the field of microwave solid flow measurement. The MF3000 microwave solid flow meter utilizes state-of-the-art microwave technology and is suitable for measuring the mass flow rate of solids in metal-lined pipes over a wide range from kg/h to t/h. This system is suitable for the online monitoring of solid flows such as powders, dusts, small balls, and granules that are transported by pneumatic means or through free fall (1 mm–20 mm). Limestone powder flow meter, limestone flow meter, desulfurization powder flow meter, activated carbon flow meter – easy to install; the sensor is tightened flush inside the pipe through welding. The sensor is connected to a transmitter mounted on a DIN rail, offering 4-20mA, RS232, and RS485 outputs; it is easy to debug using our MF-SMART software and to calibrate with a reference flow. Technical advantages: ● Suitable for pneumatic conveying systems and free-fall conveying processes ； ● Suitable for all solid materials, ranging from several kg/h to several t/h ； ● No armored protection is required inside the pipe, and the internal components are installed flush ； ● Non-contact measurement, unaffected by temperature, pressure, or vibration ； ● The measurement speed is very fast, with good static repeatability ； ● Static particles such as sediments have no effect on this ； ● The distance between the sensor*transmitter reaches 1200 meters ； ● Limit alarm monitoring, with alarm contacts ； ● High-sensitivity MF3000-S suitable for extremely low flow rates ； ● MF3000-D suitable for high pressure ； ● Applicable to zone types 20 and type 1 (EU explosion protection certification) ； ● Durable stainless steel casing ； ● No moving parts, wear-resistant, requires minimal maintenance.
