Emerson Announces Explosion-Proof Micro Motion Liquid Density Meter
Austin, TX - Emerson Process Management announces the introduction of an explosion proof/flame proof certified version of its Micro Motion 7835 custody transfer density meter. This new version includes all the features and 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.
Certified to ATEX II 2 G EEx d IIC T6 and T4 (EN50014 and EN50020 for use in Europe), Emerson's 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.
Depending on the functionality required, the 7835 density meters can be specified as a frequency output sensor version (requires external signal converter or flow computer) or as a transmitter version with integral communications (Modbus RS-485 and two 4-20 mA outputs).
The Micro Motion 7835 density meters are factory calibrated and no on-site calibration is necessary. The calibration is traceable to UK National Standards through Emerson's on-site accredited density laboratory.
Micro Motion density and concentration meters are built to tackle the most demanding process and fiscal applications. Rugged and reliable straight tube meters, with very low maintenance, they are the industry standard for on-line density measurement.
