Explosion-proof/flame-proof custody transfer density meter
The unit features class-leading performance of the 7835 density meter, while eliminating the barriers and galvanic isolators required with intrinsically safe instruments. This simplifies installation and significantly reduces project costs, according to the manufacturer. Certified to ATEX II 2 G EEx d IIC T6 and T4 (EN50014 and EN50020 for use in Europe), Emerson¹s range of Micro Motion liquid density meters is favored by the oil and gas industries for custody transfer and fiscal applications and widely used for routine control applications in chemical and other processing industries. The 7835 Series density meters offer high accuracy measurement in a very low maintenance and highly versatile unit. The vibrating element is manufactured from Ni-Span-C for excellent long term stability and low temperature coefficient. All other wetted parts are ANSI 316L stainless steel. There are no moving parts or seals, and the unit is unaffected by vibration, or by variations in flow and pressure. Its straight through design is easy to install and clean, and minimizes pressure drop for better energy efficiency.
