Shanghai Metrology Institute and Yokogawa jointly established the "Flow Measurement Public Welfare Activity"

Views: 1     Author: Site Editor     Publish Time: 2022-05-05      Origin: Site

Flow measurement is an important part of energy measurement. Because flow is a dynamic quantity, flow measurement is a complex technology. Establish a base and standard device for flow measurement to ensure the accuracy of quantity transfer and flow measurement. The variety, specification, accuracy and reliability of flow meters cannot meet production requirements. Especially for corrosive fluids, dirty fluids, highly viscous fluids, multiphase fluids, extra-large flow, micro-flow, etc., effective measurement methods need to be developed.

In mid-December, the Shanghai Metrology Institute and Yokogawa jointly launched a flow "flow measurement public welfare activity". Yokogawa presented the Shanghai Metrology Institute with flow measuring instruments and auxiliary equipment, including electromagnetic flowmeter standard tables, data recorders, flowmeters, pressure transmitters, pressure measuring instruments, etc., for the construction of a new generation of water flow standard devices. And flow measurement verification, calibration services, etc.

Electromagnetic Flowmeter

It is a new type of flow measuring instrument developed rapidly with the development of electronic technology in the 1950s and 1960s. Electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow ofcustom magnetic flow transmitter - Hiltech conductive fluid according to the electromotive force induced by the conductive fluid passing through an external magnetic field. The structure of electromagnetic flowmeter is mainly composed of magnetic circuit system, measuring conduit, motor, shell, lining and converter.

Data logger

It is an electronic instrument that obtains measurement results from sensors, data recorders and sensors work together to convert physical quantities and excitation signals to be measured into electrical signals, and store these results for backup. It is convenient for further analysis and processing, such as various recorders, light recorders, plotters, tape recorders, etc. Data loggers include hardware equipment including sensors, oscilloscopes, digital memory, waveform memory, signal conditioning equipment, and analog-to-digital conversion hardware.

Water flow standard device

There are many varieties of flow meters, which are suitable for various conditions of use, and the accuracy requirements are getting higher and higher. There are many flow meters, such as turbine flowmeters, electromagnetic flowmeters, target flowmeters, rotameter variable area flowmeter, etc. The fluid is used for the calibration of the flow value. The most commonly used fluid is water. The water flow standard device is the standard equipment used to calibrate the liquid flow meter. Due to the high requirements for the instrument, the water flow standard device also brings higher requirements. For the liquid flow standard device, starting from the aspects of improving the uncertainty level of the device and improving the flow stability of the device.

Pressure Transmitters

A device that converts pressure into pneumatic or electric signals for control and remote transmission. It can convert physical pressure parameters such as gas and liquid sensed by the load cell sensor into standard electrical signals (such as 4~20mADC, etc.) to supply secondary instruments such as indicating alarms, recorders, and regulators for measurement and indication. and process regulation. There are two types of pressure transmitters: electric and pneumatic. It is the most commonly used sensor in industrial practice. It is widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electricity, ships, machine tools, pipelines and many other industries.

Pressure measuring instrument

The force that acts vertically and uniformly on a unit area is called pressure, also known as pressure. Industrial automation instruments used to measure gas or liquid pressure, also known as pressure gauges or pressure gauges. Pressure measuring instruments are divided into liquid column type, elastic type, load type and electric test type according to the working principle. Pressure is an important parameter in industrial production. For example, when the pressure of a high-pressure vessel exceeds the rated value, it is unsafe and must be measured and controlled. Under certain conditions, the measured pressure can also indirectly obtain parameters such as temperature, flow and liquid level.

Yokogawa Electric Group

Yokogawa Electric Corporation of Japan, a world-renowned leader in measurement, industrial automation control, and information systems.
