Emerson Process Management announces the release of two new critical options for its Brooks Instrument Quantim Coriolis family of low-flow measurement products. A Hastelloy C-22 Coriolis sensing tube is available for use in environments encountering corrosive fluids, and the high-pressure option can be specified for use in applications with pipeline pressures up to 4500 psi (300 bar). These options can be provided on the QMBM (meter) and QMBS (sensor) products.
Emersons Hastelloy tube option has been introduced as a further safeguard against particular types of corrosion. The basic Quantim design incorporates a patent-pending tube-to-body joining technology in which the sensing tube is sealed to the body with a high-purity weld, thus significantly reducing corrosion potential. The Hastelloy tube further protects Quantim from chlorides or other similar applications where stress corrosion may be a concern, or in applications where erosion of the stainless steel tube may occur over time. Hastelloy is considerably more corrosion-resistant to chlorides than the standard 316L stainless tube, which can be vulnerable to stress corrosion in this type of service.
The high-pressure option should be specified for any application with a maximum pressure between 1500 and 4500 psi (100 and 300 bar).
According to Emerson, Quantim is the lowest flow Coriolis meter and controller available on the market today. Users can change liquids or gases without switching meters or recalibrating the device. Quantim has no moving parts in the area where process liquids and gases flow, which minimizes maintenance requirements. In addition to measuring mass flow, the device can simultaneously measure density and temperature, making it a true multivariable instrument. Piping and wiring during installation are dramatically simplified since Quantim has a fully integrated sensor, transmitter, valve and control electronics. With a footprint the size of a handheld organizer, the basic model fits neatly into tight spaces.
