Description (1) Description of flange Short connection flange shall execute relevant technical requirements in state standard GB/T***5.1~***5.*****0, or special standard such as American or European standard as required by user. (2) Description of structure a. For actual dimensions of high temperature or temperature/pressure compensation inserted type flowmeter, ex-factory (order) status shall govern. b. When media temperature of high temperature type flowmeter is >**0, the instrument must be installed up-side-down and horizontally. The design shall consider sufficient mounting space. c. If the media flow up-down or down-up, for ordering, please note: right view, left view (showing gauge head). In this design, only fixed inserted type is provided; if telescopic online removable type is required, particular size shall be determined with manufacturer.
