Level Measurement for Crude Storage

Series 3 ASME B31.1 float-actuated level switches are designed, built, and certified to the requirements of ASME B31.1 power piping codes. They are ideal for critical alarm set points in clean liquid applications.

Series 3 ASME B31.3 float and displacer-actuated level switches are designed, built, and certified to the requirements of ASME B31.3 process piping code requirements. They are ideal for critical alarm set points in clean liquid applications.

Series 3 NACE float and displacer-actuated level switches are designed, built and certified to meet NACE MRO175 and MRO103 requirements. They are ideal for alarm and control set points in sour liquid applications.

All welding is performed by qualified welders and per procedures required by the ASME Boiler Pressure Vessel Code Sec. IX. Carbon steel pressure boundary parts are post weld stress relieved. All welds and heat-affected zones are hardness tested to ensure compliance with NACE maximum hardness requirements.

Series B73 and series 75 external cage type level switches are completely self-contained units designed for side mounting to a tank or vessel with threaded, socket weld or flanged pipe connections. These float-actuated controls have proven their reliability in process control for decades.
