Effects of mass flowmeter scale measurement and its solutions

Abstract: the factors influencing the mass flowmeter scale measurement and solution information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Mass flowmeter directly measured through the medium of mass flow meter, can also be measured medium density and indirect measurement of the temperature of the medium. To accurate measurement data, there will not be able to influence factors, but in the use of flowmeter can not avoid some factors. More flow meter manufacturers choose model price quote you are welcome to inquire, here are the influencing factors of mass flowmeter scale measurement and solution article details. Mass flowmeter directly measured through the medium of mass flow meter, can also be measured medium density and indirect measurement of the temperature of the medium. To accurate measurement data, there will not be able to influence factors, but in the use of flowmeter can't avoid the influence of some factors, in simple terms that some factors affect the mass flowmeter measurement and solution. 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. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
