Compressed Air and Gas Flow and Consumption Meters
Measuring the flow and consumption of compressed air and gas is an important task in the manufacturing industry to optimize energy efficiency and save costs. SUTO compressed air flow meters and SUTO air and gas flow monitoring systems provide accurate measurements of air and gas consumption. These SUTO compressed air flow measurement systems enable manufacturers to track and control their compressed air usage, reducing waste and improving overall efficiency.
Los medidores de flujo SUTO iTEC para aire comprimido y gases proporcionan mediciones precisas y confiables del flujo y consumo, y vienen con varias opciones de interfaz de señal (analógica de 4-20 mA, pulso, Modbus/RTU, Modbus/TCP, M-Bus, HART).
IMPORTANCIA DE LA MEDICIÓN DEL FLUJO DE AIRE COMPRIMIDO Y GAS
Casi cualquier proceso industrial utiliza aire comprimido como una de sus fuentes de energía. El aire comprimido es fácilmente accesible y está disponible en todas las fábricas y plantas como una forma confiable de energía. Pero mientras es común medir el consumo de energía eléctrica, a menudo se encuentra que el aire comprimido como fuente de energía no es medido ni monitoreado. Un flujo de aire comprimido constante y confiable en cualquier punto de la red es necesario para mantener el proceso bajo control.
