The ROTAMASS mass flow meter is available in both integrated and separate types; each type is equipped with a high-precision digital signal processing circuit to ensure accurate and stable measurement of mass flow. The ROTAMASS mass flow meter uses explosion-proof converters and intrinsically safe sensors for use in hazardous applications. The signal processing circuit, the protective casing, and the special isolation system that protects the sensors from external loads and vibrations enable the ROTAMASS mass flow meter to deliver excellent performance in practical applications.
