The METPOINT FLM flow meter measures the compressed air volume flow, which is the basis for accurate consumption analyses for cost reduction and effective energy management. METPOINT FLM sensors reliably detect leakage, overloads and malfunctions. Based on the analysis of the sensor data, the components of the compressed air system can be adjusted for optimum efficiency.
