HyperFlow downhole flowmeter

HyperFlow
downhole flowmeter

This HyperFlow gas flowmeter is designed for measuring the flow of natural gas adjusted to standard conditions at gas production sites, storage and transportation facilities. It can measure in direct and reverse flow as a self-contained metering device and as part of an automated accounting and control system or for data transmission to other systems. These flowmeters are designed for installation on pipelines with nominal diameters of DN100 and DN150. The flow measurement range is 400 to 350,000 Sm3/h, at working pressure of up to 16.0 MPa; or 25.0 MPa.

The flowmeter is installed complete with a cover and a heat insulator for ingress protection. To inhibit hydrate formation, the flowmeter includes a temperature stabilization unit BTS-003.

HyperFlow gas flowmeters are designed for use in explosion hazardous areas in accordance with the types of explosion protection of individual components, which bear the markings «1ExibIIAT5X» and «2ExmIIT5X» respectively.

Application fields

  • production wells
  • underground gas storage (UGS) wells

Measuring principle:

Operation of the HyperFlow flowmeter is based on measurement of the pressure differential created in the pipeline with a non-standard constriction device. In the narrowed section, the velocity and kinetic energy of the flow increase. Consequently, the flow pressure downstream of the constriction device is less than the flow pressure upstream of it.
