Abstract: the interference factors of the
mass flowmeter scale measurement and processing method of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
As we all know, the quality of the mass flowmeter can accurately measure the fluid directly, and the density and temperature.
In the use of the mass flowmeter, only guarantee the mass flowmeter without interference factors, measured results to be more precise.
Tianchen.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is the interference factors of the mass flowmeter scale measurement and processing method the article details.
As we all know, the quality of the mass flowmeter can accurately measure the fluid directly, and the density and temperature.
In the use of the mass flowmeter, only guarantee the mass flowmeter without interference factors, measured results to be more precise.
Tianchen bo rui small make up of the interference factors of the mass flowmeter measurement are summarized and the processing method, now share with you.
1, the influence of vibration on mass flowmeter accuracy.
Processing method: avoid vibration interference, if can't avoid, isolation measures should be taken to isolate flow meter and the vibration interference sources.
2, the electromagnetic interference on the influence of the mass flowmeter accuracy.
Processing method: mass flowmeter installation should be far away from the large transformer, motor and other large magnetic field equipment.
3, the influence of the stress of mass flowmeter installation accuracy.
Methods: a.
Flowmeter installation should strictly abide by the specification.
b。
After the installation of the flow meter, with the hand operator or the transducer interface out & other;
Zero menu & throughout;
Default, and record producer zero zero at zero value again after the observation, both before and after the two values to ensure an order of magnitude, if the differences between the two values, then install the stress is too big, should be reinstalled.
4, oil gas is contained in the impact on the accuracy of mass flowmeter.
Methods: a.
Improve the working conditions of oil, which contains bubbles evenly distributed as far as possible, to achieve the requirement of the normal flow meter, computation;
b。
Mass flow meter installed upstream gets to minimize gas-liquid mixing phenomenon;
c。
Installed in strict accordance with the mass flowmeter specification: measuring oil medium flow pipe down 5 installation, the influence of temperature change on the accuracy of mass flowmeter.
Methods: a.
The influence of temperature on the flow meter measuring tube metal elastic can be solved by setting temperature correction coefficient;
b。
Temperature effect on the stability of the zero point, in practical applications, the need to operating temperature conditions, to the zero mass flowmeter to zui small effect.
6, stress change on the influence of the mass flowmeter accuracy.
Processing method: for ShuZhuan pressure change is big and the custody transfer of oil, need to install pressure transmitter in downstream of the flow meter, in real-time for pressure compensation in the form of software.
7, oil density and viscosity influence on accuracy of mass flowmeter.
Processing method: flowmeter should be used in the measurement of the single or the density difference of oil, the handover for bulk quantity of oil mass flowmeter must use online real flow calibration, and equipped with on-line densimeter.
8, sounding pipe damage or corrosion effect on the accuracy of mass flowmeter.
Methods: a.
Flowmeter front-end corresponding filter installation, to prevent foreign matter to enter;
b。
Use special material flow meter.
Tianchen bo rui is the present domestic zui small mass flowmeter factory, stabilize the production technology of the mass flowmeter.
Core sensitive unit adopts mechanical tooling + vacuum brazing technology, ensure product consistency.
Measuring pipe precise matching control, to ensure that the symmetric double tube structure.
Sounding pipe stress relieving technology, reduce the sensor drift.
Balance vibration control technology, to ensure that the sensor coupling vibration zui is small.
The whole machine aging technology, to ensure system stability, reduce the system drift.
To ensure the stability in the process of measurement.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
In the office, various are considered essential since they are used to achieve particular tasks in the office. Among these , mass flow meter, vortex flow meter manufacturer, and rosemount
coriolis mass flow meter are widely used.
