Abstract
In an embodiment, a method for measuring parameters of a liquid, where the method includes measuring pressure drops across a flow meter, measuring pressure upstream of the flow meter, and identifying at least one liquid parameter based, at least in part, on a correlation of a change in a multiphase flow parameter to pulse output. In an additional embodiment, a measuring apparatus for measuring parameters of a liquid, where the measuring apparatus includes an electronic control operable to measure pressure drops across the measuring apparatus, measure pressure upstream of the measuring apparatus, and correlate a change in a multiphase parameter to measured pulse output of the measuring apparatus.

A method for measuring parameters of a liquid using a multi-phase flow meter, the method comprising:
- measuring pressure drops across the multi-phase flow meter, the multi-phase flow meter comprising:
- a flow conduit;
- a rotor positioned in the flow conduit, the rotor comprising a plurality of blades;
- a first pressure sensor disposed upstream of the rotor;
- a first temperature sensor disposed upstream of the rotor;
- a second pressure sensor disposed downstream of the rotor;
- a second temperature sensor disposed downstream of the rotor;
- a pulse sensor disposed in the flow conduit proximate the plurality of blades;
- a nozzle disposed positioned in the flow conduit upstream of the rotor;
- and
- a control unit is electrically coupled to the first pressure sensor, the second pressure sensor, and the pulse sensor, and the control unit is configured to determine a gas volume fraction from an output of the first pressure sensor, the second pressure sensor, and the pulse sensor;
- measuring pressure upstream of the multi-phase flow meter;
- and
- identifying at least one fluid parameter based, at least in part, on a correlation of a change in a multiphase flow parameter to pulse output.
