Integral and Remote Style Thermal Mass Flowmeters

Integral style thermal mass flow meters are assembled with all electrical components and connections located within one enclosure. Depending on the specific application, the enclosure may be either explosion-proof cast aluminum or NEMA 4X for non-hazardous environments. In either case, the enclosure is mounted directly to the inline or insertion assembly.

Remote style thermal mass flowmeters utilize two enclosures. One enclosure is mounted to the inline or insertion assembly as noted above with the same explosion-proof or non-hazardous area options. The second enclosure is typically NEMA 4X, and it includes the all of the electrical connections as well as the linearizing electronics. Only a two-wire, twisted-pair cable is required to carry the input power and flow signal between the two enclosures.
