In the field of industrial fluid measurement, high-pressure turbine flowmeters, with their high precision and resistance to harsh operating conditions, have become essential equipment in the petroleum, chemical, and energy industries.
Sino-Inst’s HP series of high-pressure turbine flowmeters (HP stands for High Pressure Connection) are designed to measure continuous and discontinuous flows at very high operating pressures. They are primarily used for lubricating and non-lubricating media, and are particularly well-suited for low- and medium-viscosity fluids such as water, emulsions, additives, and inhibitors.
In addition to high-pressure turbine flowmeters, we also offer custom designs for high-pressure electromagnetic flowmeters, high-pressure gear flowmeters, and high-pressure mass flowmeters. Please feel free to contact us!
