Abstract
Methods and apparatus for detecting water in multiphase flows are disclosed. An example apparatus includes a conduit including an inlet to receive a multiphase flow and an electromagnetic sensor coupled to a liquid-rich region of the conduit to measure a permittivity of the multiphase flow, and a water detection manager to determine that water is detected in the multiphase flow based on the permittivity.
Claims20
An apparatus, comprising:
- a conduit including:
- an inlet to receive a multiphase flow;
- and
- an electromagnetic sensor coupled to a liquid-rich region of the conduit to measure a permittivity of the multiphase flow;
- and
- a water detection manager to determine that water is detected in the multiphase flow based on the permittivity.
3 more elements
A method, comprising:
- determining a first permittivity and a second permittivity of a multiphase flow based on electromagnetic data obtained from an electromagnetic sensor;
- comparing a difference between the first permittivity and the second permittivity to a water detection threshold;
- and
- in response to the difference satisfying the water detection threshold, generating an alert indicating that water is present in the multiphase flow.
1 more element
A non-transitory computer readable storage medium comprising instructions which, when executed, causes a machine to at least:
- determine a first permittivity and a second permittivity of a multiphase flow based on electromagnetic data obtained from an electromagnetic sensor;
- compare a difference between the first permittivity and the second permittivity to a water detection threshold;
- and
- generate an alert indicating that water is detected in the multiphase flow when the difference satisfies the water detection threshold.
