The report shows experience in implementing two-phase flow-meters for helium, hydrogen, liquefied natural gas (LNG), and oil-salty/formation water mixtures. Two types of such devices are presented. The first type is flow-meters based on combination of a void fraction RF-sensor and a narrowing device. They can be applied for superconducting accelerators cooled with two-phase helium, refueling hydrogen system for space ships and oil production industry. The second one is based on combination of a gamma-densitometer and a narrowing device. These systems can be used for the diagnostics of LNG and oil-formation water flows. A measuring system based on a modular industrial computer is described as well. The metrological characteristics for different flow-meters are presented and the results obtained are discussed. It is also shown that the experience gained allows separationless flow-meters for three-phase oil-gas-formation water flows to be produced.
