In the scheme, the filter 20 is arranged, so that impurities in the crude oil can be filtered out to protect the pressure pump 30. The pressurizing pump 30 is arranged to pressurize the crude oil sample to be mixed with further oil and water, so as to ensure that the crude oil sample passes through the densimeter 50 and the water content analyzer 60 in sequence at a certain flow rate and in a mixed state.

Because the influence of the attachment of the probe on the measurement is avoided in principle, no additional deviation is generated due to the pollution of the probe.
The densitometer 50 is installed at a position close to the inlet side of the moisture analyzer 60; the manual sampling port 80 is installed at a position adjacent to the outlet side of the water content analyzer 60. Therefore, the density meter 50, the water content analyzer 60 and the manual sampling port 80 are arranged close to each other, so that the flow fields of the mixture of the crude oil and the water flowing through the three are ensured to be consistent as much as possible, and the detection precision of the instrument is improved.

In order to realize online real-time detection, the scheme is also provided with a data acquisition and control device 70; the data acquisition and control device 70 is connected to the pressure pump 30, the pressure transmitter 40, the densimeter 50, the moisture analyzer 60, the manual sampling port 80, and the sampler 90, respectively. The data of the connected instrument is acquired by the data acquisition and control device 70 for subsequent processing, for example, the data is uploaded to a cloud server through a network module of the data acquisition and control device 70 itself or is transmitted to a remote device for display, etc.
Specifically, the data collection and control device 70 may include a data collection system outdoor unit: the system is arranged in an explosion-proof control box in the system, and realizes the acquisition of field signals, processing and the realization of HMI data communication of an indoor unit through a PLC (Programmable Logic Controller) and an input/output and communication module; further comprising: indoor HMI (Human Machine Interface, Human Machine Interface or Human Machine Interface) unit of data acquisition system: the System is used for data display/record, System configuration, diagnosis/alarm information, analysis System calibration/comparison and signal communication with an upper computer or a Distributed Control System (DCS), and oil-water mixing correction software is arranged in the HMI and is used for correcting the oil-water mixing state; specifically, the data collection and control device 70 may further include a network module, such as a 4G module, and may further install a corresponding APP (application) on the terminal, and connect the cloud server connected to the data collection and control device 70 through the APP installed in the mobile terminal device, so as to monitor process variables, system detection values, alarms, and diagnostic information.
Therefore, the system formed by a plurality of instruments in the scheme realizes real-time continuous measurement of the crude oil, the consistency of the analyzed result is good, and the final result cannot be directly influenced by artificial factors. And based on the setting of densimeter 50 and moisture analyzer 60, this scheme can gather moisture analyzer 60 output's moisture content and the moisture content that the density based on densimeter 50 detects was obtained through the density method simultaneously. Therefore, when the water content is lower than 50%, the system simultaneously obtains two water contents, and the water content output by the water content analyzer 60 is taken as a final output value; when the water content of the monitored crude oil is higher than the working range (generally about 50%) of a microwave method, the moisture meter outputs over-range information, and the system selects the water content measured by an output density method as the output water content of the system, so that the online moisture analysis system can measure the water content in a full-range and without a blind zone. Through tests, the scheme can realize no blind zone within the range of 0-100% of water content.
