Being a small diameter, 28 mm in size, this model contributes to space-saving by its integrated mounting.
Since wetted part of GW28 consists of simple construction with diaphragm, unlike a conventional C-shaped　bourdon tube, cleaning and a gas flushing are easily available to user.
Internal volume around wetted part is reduced to approximately half as compared to conventional small bourdon　tube type gauge eliminating pocket substantially preventing gas from staying at the part.To maximize performance, please select the pressure range with your common operating pressure should be　30 to 65% of the pressure range. Furthermore, please ensure that the wetted parts materials listed are suitable　for the use against measuring gas or liquid.
