What should be taken into consideration when selecting or manufacturing the mating flanges for flanged transmitters? Reference answer: ① The pressure rating should be the same as or higher than that of the instrument flange ； ②The nominal diameter should be equal ； ③The sealing surfaces of the flanges should be identical ； ④The number and spacing of bolt holes should be the same.
Flange specifications, pressure rating, and seal surface type
When selecting or manufacturing the mating flanges for a flanged transmitter, the following points should be taken into account: ① The pressure rating should be the same as or higher than that of the instrument flange； ②The nominal diameter should be equal ； ③The sealing surfaces of the flanges should be identical ； ④The number and spacing of bolt holes should be the same.

Size, material, pressure tolerance, screw hole spacing
Attention should be paid to the material, pressure, nominal diameter, and sealing surface of the mating flanges
①The pressure rating should be the same as or higher than that of the instrument flange； ②The nominal diameter should be equal ； ③The sealing surfaces of the flanges should be identical ； ④The number and spacing of bolt holes should be the same.
