The new Sitrans LG series is a flexible portfolio of guided wave radar transmitters suitable for virtually any type of industrial application. The modular design of the four basic versions, with numerous configuration options, allows for level measurement in the…
Effective level measurement in the chemical process industries (CPI) helps maintain material inventory at economic quantities, improves product quality and maximizes plant output by avoiding spills and process upsets. When they are incorrectly matched to their application, level-measurement devices can…
Dilute-phase pneumatic conveying systems must be operated in a certain sequence and have sufficient instrumentation and operating controls to assure reliable operation and prevent problems. This article discusses two subjects that are important for successful dilute-phase conveying. Discussed below are…
Corrosion to the external surface of process piping and vessels that is hidden under the insulation is referred to as corrosion under insulation (CUI). Aging piping and equipment in chemical plants and petroleum refineries have made CUI detection and assessment…
The Sitrans FC410 (photo) is said to be the lightest, most compact Coriolis flowmeter available, and features a high measuring accuracy of 0.1%. The device has dimensions of 265-mm length, 280-mm height and 90-mm width, and a weight of 4.6…
The HS-20 Series of headspace samplers provide a reliable and robust headspace solution for any application analyzing volatile components in a difficult matrix. The HS-20 Series consists of two modules: a loop model for the traditional static headspace methods, and…
The Sencom platform-product series now includes modules for the digital measurement of pH and ORP (oxidation-reduction potential), joining the existing FLXA21 two-wire pH/ORP transmitter. The platform consists of a Sencon module, the FU20F pH/ORP sensor, a Sencon cable and the…
Several new operator-interface touchscreen panels have been introduced for this company’s Compact control products.
