Frequency Processing And Temperature-Pressure Compensation Of The Vortex Flowmeter Based On Two-Phase Flow

Abstract

Aiming at a new type and multi-functional intelligent vortex flowmeter integrating system, which implicates whether it is liquid, gas, steam or the mixture of oil and gas, or in special conditions such as high temperature, high pressure, the medium can be measured intelligently. Especially for mixed media by TPF (Two-phase Flow), such as oil and gas, water vapor, firstly separates the mixed fluid through the gas-liquid separation device, and then rolls up the vortex signal, temperature and pressure of separated fluid into one, and finally a stable and accurate result is obtained by inputting the mixed signal through the integrating system. Thus, the applicability and reliability of the flowmeter can be greatly enhanced, which ensures the authenticity and stability of the measurement data about the fluid.

Automatic Measurement Of Shape Parameters For Hydraulic Torque Converter

“…Modes is to perfect the function of Measurement System, and meet the demands of industrial production better. The main functions of these modes are as follows: ① Add all the specification parameters and the given tolerance measuring range of the shape parameters of the measured work piece, and then to save these data to the database from these models; ② Query the data, which the Automatic Mode measured and saved in the database, according to the relevant conditions, and then to export the data which meet the conditions in EXCEL tabular form [20][21]; ③ Statistics for the data, which the Automatic Mode measured and saved in the database, according to the relevant conditions, and then to show the average value, the standard variance and the distribution histogram of the data which meet the conditions; ④ Realize the real-time control of the whole measuring process of the Hydraulic Torque Converter shape parameters for using the corresponding program module to achieve two-way real-time communication with the Master Control Computer and the PLC.…”

Optimization of Modified Rotameter Using Hall Probe Sensor with Respect to Liquid Density and its Calibration Using Artificial Neural Network

“…Nasrin Afsarimanes et al [19] gave a calibration method using LabVIEW software for characterizing and optimizing thermal sensors like thermistors and RTD. Zhang Haining et al [24] gave an algorithm for temperature-pressure compensation using two-phase flow for vortex flowmeter. This method can be used in petroleum and chemical industries where the input that is crude oil contains a mixture of gases.…”
