Factors affecting the mass flowmeter measurement and their solutions The mass flowmeter directly measures the mass flow of the medium through the flowmeter. It also measures the density of the medium and indirectly measures the temperature of the medium. To accurately measure data, there can be no influencing factors, but the influence of some factors cannot be avoided when using the flow meter. Simply speaking, some factors influence the measurement and solution of the mass flow meter. Shenyang SanLand designs and manufactures cutting edge Mobile Crushing Equipment for customers in the materials processing industries.

1 , the impact of vibration on the accuracy of the mass flow meter. Treatment method: Avoid vibration interference. If it can not be avoided, isolation measures should be taken to isolate the flowmeter from the sources of vibration interference.
2. The influence of electromagnetic interference on the accuracy of the mass flowmeter. Treatment method: The mass flowmeter should be installed away from large transformers, motors and other devices that generate large magnetic fields.
3 , the impact of installation stress on the accuracy of the mass flowmeter. Treatment method: a. Flowmeter installation should strictly abide by the installation specification. b. After the flow meter is installed, use the communicator or the transmitter interface to call up the “ zeroing menu †and record the factory default zero value. After zeroing, observe the zero value at this time. The two values ​​must be guaranteed before and after An order of magnitude, if the difference between the two values ​​is large, it means that the installation stress is too great and should be reinstalled.
4. The influence of the gas contained in the oil on the accuracy of the mass flowmeter. Treatment methods: a. Improve the working conditions of the oil product so that the contained air bubbles are distributed as evenly as possible to meet the requirements of the normal measurement of the flow meter; b. The mass flow meter installs the air eliminator upstream to minimize the gas-liquid mixing phenomenon; c. Installed in strict accordance with the specifications of the mass flow meter installation: Measurement of oil medium flow tube downwards installation
5 , the impact of temperature changes on the accuracy of the mass flow meter. Processing methods: a. The effect of temperature on the metal elasticity of the flow meter measuring tube can be solved by setting the temperature correction coefficient; b. The effect of temperature on the stability of the zero point. In practical applications, the mass flow meter needs to be operated under the operating temperature condition. Field zeroing is performed to minimize the impact.
6. The effect of pressure change on the accuracy of the mass flowmeter. Treatment method: For oil products with large changes in transmission pressure and trade delivery, a pressure transmitter must be installed downstream of the flowmeter to perform pressure compensation in real time by means of software.
7. The influence of oil density and viscosity on the accuracy of the mass flowmeter. Treatment method: The flowmeter should be used on oils with little difference in measurement or density, and the on-line real-flow calibration must be adopted for the mass flowmeter used for the bulk oil transfer, and equipped with on-line density meter.
8. The effect of measuring pipe damage or corrosion on the accuracy of the mass flowmeter. Treatment methods: a. Install corresponding filters on the front of the flowmeter to prevent foreign matter from entering; b. Use special material flowmeters.
