Aumeascon AM-MFM Electromagnetic Flow Meter
Aumeascon Electromagnetic flow meters , also known as Magnetic flow meters or mag meters, are often selected because they are obstruction less, cost-effective, bi-directional, and provide highly accurate volumetric flow measurement. A range of liner materials, electrode options and line sizes accommodate a wide variety of process applications. For aggressive high noise applications, look to our Slurry Platform for optimum performance. See if a Slurry mag meter meets your needs.
Working principle
Electromagnetic flow meters, or magmeters, are comprised of a transmitter and sensor that together measure flow. The magnetic flow meter’s sensor is placed inline and measures an induced voltage generated by the fluid as it flows through a pipe. The transmitter takes the voltage generated by the sensor, converts the voltage into a flow measurement and transmits that flow measurement to a control system.
