A system (10) and method for measuring fluids include a vessel (12) containing at least two fluids with a drain pipe (14), a seal housing (22), a tool assembly (40), and a float assembly (60). The seal housing fits onto the drain pipe of existing vessels or tanks, and the tool assembly and float assembly are inserted through the seal housing to the vessel to measure the fluids inside the tank. The tool assembly has a shaft section (42) and a flexible section (50). The flexible section extends into the vessel and through any bend in the drain pipe so that the system is compatible with retrofitting vessels with different drain pipe shapes. The float assembly can be released from the end of the bent drain pipe to float to the fluid boundary between different fluids in the vessel. The float assembly can also be retracted to safe position within the seal housing.

DUAL CHAMBER SYSTEM AND METHOD TO GENERATE STEAM FOR CALIBRATION
The dual chamber system 10 has a source chamber 20 and a receiver chamber 40. The source chamber 20 generates a first steam 30 in a first steam section 24, and the receiver chamber 40 generates a second steam 50 in a second steam section 44. The first steam is at a higher temperature than the second steam, and the first steam is at 100% quality. The first steam is injected into a mixing section 52 of the receiver chamber 40 to generate a condensed steam 62. A sensor or instrument can then be calibrated by the condensed steam. The measurement being taken with the sensor or instrument will have reliability and accuracy. The method includes generating the first steam 30, generating the second steam 50, injecting and mixing the first and second steam to form condensed steam 62 at a metering point 70 in the receiver chamber 40, and calibrating a sensor or instrument at the metering point 70.
A system and method for controlling steam based on a determination of steam quality include a steam conduit defining an interior volume of steam, an emitter for first and second coherent light beams, a receiver for signals resulting from an interference pattern of the first and second coherent light beams after refraction from a droplet in the steam at a convergence point, and a processor to determine steam quality based on the signals. There can be more than one receiver to account for phase differences related to droplet shape and size. The steam quality is also assessed by measuring droplet velocity by frequency of the interference patterns, and steam vapor and the refraction element of the scattering from the liquid droplet by absorption spectroscopy. The system can be utilized with on-line and real time measurements for on-line and real time determinations of steam quality.

The flow meter system (100) includes flow meters (110, 120, 140) taking measurements based on a set of parameters of a multiphase fluid (102), each measurement corresponding to respective groups of interrelated unknown variables. These unknown variables are selected from the set of parameters, and the groups of unknown variables are different from each other. A processor uses an iterative process to solve equations of a mathematical model, determined by the equations corresponding to the measurements and groups of unknown variables, so as to estimate an amount of a target unknown variable selected from the set of parameters. The method for estimating a target unknown variable of a multiphase fluid (102) includes installing flow meters (110, 120, 140) in the multiphase fluid (102); taking measurements based on a set of parameters; determining a mathematical model with equations corresponding to the measurements and groups of interrelated unknown variables; and solving equations with an iterative process.
A method and system for on-line multi-component fluid analysis, the system can be configured to measure the absolute viscosity using data acquired by monitoring the time it takes for a pump to move from one side to the other side and pressure at the discharge for a reference fluid and the time it takes for a pump to move from one side to the other side and pressure at the discharge for a sample fluid. The system and method can also include comparing the data acquired for the sample fluid and the reference fluid. The system and method can present rheological behavior of the sample fluid as Newtonian viscosity and the shear rate in real time.

A method and apparatus for installing a device in a storage vessel having a drawline while the storage vessel is in operation is disclosed. A cutting tool is run through the drawline from a distal location to a location inside the storage vessel. The cutting tool is used to create an opening in the drawline at the location inside the storage vessel. The device is installed at the created opening.
The present disclosure provides a flowmeter including a vibrating element configured to be inserted in a measured fluid; a driver circuit to vibrate the vibrating element in its natural frequency of oscillation; one or more additional technology flow meters configured to measure an additional property of the fluid; a data acquisition circuit configured to measure signals effected by the flow of a multi-phase fluid; and a computer suitable to solve non-linear simultaneous equations. The fluid may include gas, oil and/or water. The fluid may also include solids.
A method for correcting measurements of conventional flow meters is provided. Using prior determination of fundamental behavior parameters, flow meter measurements are iteratively calculated to improve their accuracy and eliminate the need for dissimilar momentum meters or moving parts in multiphase flow metering. In some applications, corrections to meter readings are made by using an algorithm having a generic model for the entire system and validating the converged solution against realistic bounds on fluid properties.
An apparatus and method for measuring the concentrations of oil, water and/or hydrates in a multiphase production fluid flow comprises measuring the complex permitivities, both real and imaginary parts, of the flow at at least two frequencies.
