Gamma measurement (where applicable): Compact gamma system with Cs-137 source, 2mCi, 5mCi or 8.3mCi, 30.1 year half-life.

Power supply: 18 - 30 VDC or 100 - 240 VAC, power consumption less than 20W.

Communication protocols: Modbus RTU, Modbus TCP, HTTP.

Communication interfaces: RS-485, Ethernet.

Mounting: Vertical upward mounting.

Certifications: ATEX, IECEx, CSA C/US, EAC, etc., designed in accordance with ASME B16.5 and ASME B31.3 standards, materials in accordance with ASME B31.3 specifications, parts in contact with corrosive media in accordance with NACE MR0175 and ISO 15156 standards.

Measurement Uncertainty: Under 95% confidence interval, the relative uncertainty of gas flow measurement corresponding to different ranges of GVF is: 7.0% when less than 25%; 5.0% for 25 - 90%; 5.0% for 90 - 95%; 5.0% for 95 - 98%; and 5.0% for greater than 98%. The relative uncertainty of liquid flow measurement is 1/4 of the liquid flow, and the absolute uncertainty of water-to-liquid ratio measurement is 1/4 of the water-to-liquid ratio (under given conditions, such as operating pressure above 73 psi (5 bar), and requires correct PVT and water conductivity input).
