Master-Touch Series 8600MP-8700MP Flow Meter

Brand: Eldridge Products, Inc (EPI)

MP Series flow meters are approved for use in hazardous locations.

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 in the flow section for exposure to the process gas. 

Our inline style thermal mass flow meters are available in sizes from 1/4″ pipe through 4″ pipe or tube, and are provided with a variety of options such as MNPT ends, tube end fittings, butt weld ends, flanged end configurations, etc. 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.
