3、Department of Defense.1NOTEA key was editorially added to Fig. 1 in January 2018.1. Scope1.1 This specification covers the requirements for direct andindirect reading sight liquid level indicators for general appli-cations. General applications for indirect reading sight glassesare water and fuel se
4、rvice at working pressures 2.07 MPa (300lb/in.2) and below, temperatures of 149C (300F) and below.General applications for direct reading sight glasses are appli-cations in which the temperature does not exceed 66C(150F).1.2 Direct reading sight glass indicators may consist of glassor plastic tubes
5、with fittings including shutoff valves. Glasstubes may be used for low shock direct reading sight glassindicators in which the fluid is not compatible with plastic.1.3 Indirect reading indicators may consist of a sealedchamber with a magnetic float or flag indicator.1.4 Special requirements for nava
6、l shipboard applicationsare included in the supplement to this standard.1.5 The values stated in SI units are to be regarded asstandard. The values given in parentheses are mathematicalconversions to inch-pound units that are provided for informa-tion only and are not considered standard.1.6 This in

Materials and Manufa
20、cture6.1 MaterialsThe materials for all wetted parts shall beselected for long-term compatibility with the process mediumand ambient conditions.6.2 Material InspectionThe manufacturer shall be respon-sible for ensuring that materials used are manufactured,examined, and tested in accordance with the
21、specifications andstandards as applicable.6.3 Gaskets and O-RingsGaskets and O-rings shall befabricated of materials suitable to the operating pressure,temperature, and process medium for each application.7. Physical Properties7.1 ConnectionsSight indicators are usually installed us-ing standard pip
22、e fittings or flanges. Pipe fittings and materialshould match that of the existing pipe for each installation.Type and size of fittings shall be specified in the acquisitionrequirements. Welding or brazing shall be performed in accor-dance with industry standards.7.2 Flanged ConnectionsWhere sight i
