Inline Meter Installation

View the installation guide for our inline style thermal mass flow meters.

Inline Meter Installation Guide

The inline style flow meter assembly includes the flow sensing element, temperature sensing element, bridge amplifier/signal output board, microprocessor circuit board, transmitter enclosure, and flow section. Depending on the flow section size and/or other requirements, the flow section may include flow conditioning plates.

The flow section is typically specified to match the user’s flow conduit and is plumbed directly in the flow line. This design has the sensing elements mounted directly in the flow section for exposure to the process gas. Inline mounting styles are available through EPI™ for line sizes 1/4″ pipe and larger. Consult our factory for flow section end mounting options.

Inline flow meters are calibrated with the flow sensing element mounted in place within the flow section. The sensor should not be removed as the accuracy of the flow signal will be affected. Should it become necessary to remove the sensing element for any reason, the element must be replaced in the same alignment as it was originally positioned.

Consult the factory before disassembling.
