The Promass F 200 from Endress+Hauser now also measures flow rates according to the Coriolis principle in two-wire technology up to a nominal diameter of DN 80. According to the supplier, this covers almost all needs and required sizes of two-wire devices for the chemical industry. The two-wire devices are approved for use in SIL2/3 and hazardous areas. Another new function is 'Heartbeat Technology': this technology offers diagnostic functionality through continuous self-monitoring, in-situ verification of flowmeters in the application and the output of additional measured variables to an external condition monitoring system.
