Before flotation machine system test the accuracy of measurement of liquid level system was tested. Magnetic flap UNp | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

specific test method is by measuring the output current of the ultrasonic thermometer to examine the accuracy of ultrasonic thermometer; Height displayed on the controller and the actual level of the overall accuracy of measurement error to liquid level control system.

according to the design requirements, temperature control system of measuring the range is 0 ~ 500 ram, the corresponding output signal thermometer is 4 ~ 20 ma current. So, in testing, gives a practical liquid level height, ultrasonic thermometer is a theory, the output current by four current meter measure the actual current output of the thermometer, we get the output precision of the thermometer; At the same time, will be 4 ~ 20 ma current input controller, so that can read through controller display controller level measurement of the height, so as to get the overall accuracy of measurement of liquid level control system. Experiment repeated testing, every time close to the test result. UNp magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

50 m3 of flotation machine in the process of production, in general, pulp-level range in & plusmn; 200 ram, if the liquid level can be stable in & plusmn; 40 mm, can reach the use requirement, so, from the test results can be concluded that the measuring accuracy of the system satisfy the using demand of the system.
