heavy medium coal washing online density meter types
At present, the online density meter used for heavy medium coal washing are as follows:
1. The radioisotope density meter has the advantages of high measurement accuracy and less maintenance. However, due to the presence of radioactive substances, it will cause radioactive pollution to the surrounding environment and cause radioactive radiation damage to personnel; therefore, equipment and personnel must meet the regulatory requirements for the use of radioactive sources by the Health Bureau. At the same time, when the inner wall of the sampling tube is fouled, the measurement accuracy will be affected.
2. The Coriolis density meter uses the modulation effect of the fluid mass flow on the vibration of the vibrating tube to measure the flow and density, with high measurement accuracy. However, when the flow rate is slow, the pipeline will be blocked, and the sensor will be easily damaged by repeated disassembly and cleaning; when the flow rate is fast, the wear and tear will be accelerated, resulting in damage and scrapping of the mass flowmeter.
3. For the vibrating tuning fork density meter, when the liquid flows through the fork body, the vibration will change, causing the resonant frequency to change, and the accurate density value will be calculated by the electronic processing unit. When the tuning fork type density meter measures the fouling-prone medium, since there is no on-line cleaning function, the medium attached to the tuning fork will easily cause inaccurate measurement.
4. Differential pressure density meter adopts multi-parameter density sensor, automatic temperature compensation, easy installation and less maintenance.
heavy medium coal washing Differential Pressure Density Meter advantages
SPX510 Differential Pressure Online Density Meter has the following advantages:
1. Bypass installation can be used to reduce the flow rate and ensure the accuracy of measurement;
2. The shape between the measuring tube and the diaphragm seat is a bell mouth, which prevents the fluid from directly impacting the diaphragm, thereby prolonging the service life of the diaphragm.
3. With temperature compensation function to ensure the accuracy of measurement.
4. The wetted part of the density meter is made of high-density, corrosion-resistant and wear-resistant PTFE material, which reduces wear and prolongs service life.
5. With a cleaning port, the diaphragm can be cleaned online when the machine is stopped.
