Working principle of mass flowmeter and matters to be avoided during use

The working principle of the mass flowmeter and the matters to be avoided during the use of the mass flowmeter When the mass flowmeter measures the fluid flowing in the rotating pipe, it will generate a force on the pipe wall. It was discovered by Coriolis in 1832 when he studied the water turbine, referred to as science. force. The mass flowmeter is based on the Coriolis force. There are two parallel T-shaped vibrating tubes inside the sensor. The driving coil is installed in the middle and the pickup coil is installed at both ends. When the excitation voltage provided by the transmitter is applied to the driving coil , the vibrating tube vibrates periodically as a reciprocating mass flowmeter, and the fluid medium in the industrial process flows through the vibrating tube of the sensor, which will produce a Coriolis force effect on the vibrating tube, causing the two vibrating tubes to vibrate torsionally. The pickup coil will generate two sets of signals with different phases, and the difference between the two signals is proportional to the mass flow rate of the fluid passing through the sensor. The computer calculates the mass flow through the vibrating tube. When different media flow through the sensor, the main vibration frequency of the vibrating tube is different, and the density of the media is calculated accordingly. The platinum resistance installed on the vibration tube of the sensor can indirectly measure the temperature of the medium. Therefore, we should avoid the following events during the measurement process: 1. The rigidity and stress-free support of the sensor 2. Avoid installing the sensor at a higher position in the pipeline, because the air bubbles will gather and stay, causing measurement errors in the test system; 3. . If the excessively long downstream pipeline (generally not greater than 3M) ​​cannot be avoided, an additional flow valve should be installed; 4. The distance from the delivery pump should be at least 4 times the length of the sensor itself (the distance between the two flanges). Pumps cause unwanted vibrations that require isolation with coiled tubing or connecting tubing. 5. Additional devices such as regulating valves and inspection windows should be installed at least 1X 'L' away from the sensor (L is the distance between the sensor mounting flanges). 6. The bracket cannot be installed on the flange or the shell. The blue distance is 20~200mm;

For the study, researchers defined Sincerity Group as strategies to foster some social good, including programs that benefit community engagement, diversity, the environment, human rights and employee relations.
