Factors Affecting Mass Flow Meter Measurement and Solutions1

Factors affecting mass flowmeter measurement and solutions The mass flowmeter directly measures the mass flow of the medium passing through the flowmeter, and can also measure the density of the medium and indirectly measure the temperature of the medium. To accurately measure data, there must be no influencing factors, but the influence of some factors cannot be avoided when using the flowmeter. Simply put, some factors affect the measurement and solution of the mass flowmeter. 1. The influence of vibration on the accuracy of mass flowmeter. Solution: Avoid vibration interference. If it is unavoidable, isolation measures should be taken to isolate the flowmeter from the source of vibration interference. 2. The influence of electromagnetic interference on the accuracy of mass flowmeters. Treatment method: The mass flowmeter should be installed away from large transformers, motors and other equipment that generate large magnetic fields. 3. The influence of installation stress on the accuracy of mass flowmeter. Treatment method: a. When installing the flowmeter, strictly abide by the installation specifications. b. After the flowmeter is installed, use a handheld operator or call out on the transmitter interface“Zero menu”And record the preset value of factory zero point. After zero adjustment, observe the zero point value at this time. The two values ​​before and after should be guaranteed to be in the same order of magnitude. If there is a large difference between the two values, it means that the installation stress is too large and should be reinstalled. 4. The influence of gas contained in the oil on the accuracy of the mass flowmeter. Treatment method: a. Improve the working conditions of the oil product so that the bubbles contained in it are distributed as evenly as possible to meet the requirements of normal measurement of the flowmeter; b. Install an air eliminator upstream of the mass flowmeter to minimize gas-liquid mixing; c. Install in strict accordance with the mass flowmeter installation specification: measure the oil medium flow tube and install it downward 5. The influence of temperature changes on the accuracy of the mass flowmeter. Treatment method: a. The influence of temperature on the metal elasticity of the flowmeter measuring tube can be solved by setting the temperature correction coefficient; b. The influence of temperature on the zero point stability, in practical applications, it is necessary to adjust the mass flowmeter under the operating temperature condition. Perform on-site zeroing to minimize the impact. 6. The influence of pressure changes on the accuracy of mass flowmeters. Solution: For oil products with large changes in transfer pressure and custody transfer, it is necessary to install a pressure transmitter downstream of the flow meter to perform real-time pressure compensation in the form of software. 7. The influence of oil density and viscosity on the accuracy of mass flowmeter. Treatment method: The flowmeter should be used to measure oil products with a single or little difference in density. Mass flowmeters used for the transfer of large quantities of oil products must be calibrated online and equipped with an online density meter. 8. The influence of damage or corrosion of the measuring tube on the accuracy of the mass flowmeter. Treatment method: a. Install a corresponding filter at the front end of the flowmeter to prevent foreign matter from entering; b. Use a flowmeter made of special material.

One increasingly popular managerial tactic to improve problem-solving performance of mass flow meter is to increase the connectedness, or what academics call clustering, of the organization

At the heart of mass flow meter is our Vision to be the global energy company most admired for its people, partnership and performance.

Sincerity Group focuses on three key elements—process, people, and technology—the authors found that people of two seemingly opposite cultures are able to work together in a project-based environment to complement each other and reap mutual benefits for a win-win result.
