MPNH Series flow meters are approved for use in ordinary locations (see specifications)
Inline style thermal mass flow meters include a flow section that is usually specified to match the user’s flow conduit and is then plumbed directly into the process line. This design has the sensing elements mounted directly on the flow section for exposure to the process gas. Our inline style flow averaging thermal mass flow meters are available in sizes from 2″ pipe through 4″ pipe and are provided with flanged end configurations, as required. Pipe sizes in excess of 4″ typically require insertion style thermal mass flow meters.
Integral style thermal mass flow meters have all of the electrical components and connections located within one enclosure. This enclosure may be rated for either hazardous environments (MP Series) or for ordinary, non-hazardous environments (MPNH Series), as necessary. The enclosure is mounted directly to the inline flow section or to the insertion probe assembly at the point of measurement. The enclosure includes the all of the electrical connections as well as the linearizing electronics and the display/keypad assembly.
