The process measuring technology provider KROHNE has introduced new large line sizes for its OPTIMASS series, aiming to achieve continuous and repeatable mass flow or density measurement in a wide range of gas fractions and complex flow conditions
The new large line sizes for its OPTIMASS series are available for OPTIMASS 6400, with diameters DN150/ 6" and DN200/ 8" and OPTIMASS 2400, with diameters up to DN400/ 16".
Targeted at the oil and gas and petrochemical industries, typical applications for the new large line sizes include bulk hydrocarbon loading and bunkering, LNG or cryogenic or high temperature applications, according to KROHNE.
“They feature gas and liquid MID and OIML custody transfer approvals and compliance with API and AGA guidelines, SIL 2/3 functionality and NE 107 diagnostic functions,” said the company.
Available in both duplex and super duplex, OPTIMASS 2400 aims to maintain the benefits of the straight tube design including low pressure loss, small installation envelope, support on the meter body, secondary containment and immunity to crosstalk between meters installed in the same line.
“OPTIMASS 2400 is suitable for field proving with small volume prover, in-situ calibration verification and documentation with OPTICHECK verification tool is also possible,” said KROHNE.
The new large line sizes also feature entrained gas management (EGM), focusing on continuous and repeatable mass flow or density measurement in a wide range of gas fractions and complex flow conditions.
The meters also indicate and maintain operation with two-phase flows such as liquids mixed with gas, slurries with gases or highly viscous fluids with gas entrainments, the company stated.
