Description

Telescopic floating rod liquid level meter

Technical Field

At present, the liquid level measuring instruments which are used more mainly comprise an ultrasonic water level meter, a static pressure type liquid level meter and a floating ball liquid level meter. When the ultrasonic water level meter is used for measuring the liquid level height of the regulating reservoir, echo waves are easy to interfere due to fluctuation of the liquid level of the regulating reservoir, and the medium in the regulating reservoir is complex in composition, easy to generate foams, easy to absorb sound waves or interfere emission of the sound waves, and finally, the measurement error is large. In addition, because the medium in the equalizing basin easily produces and easily fires and poisonous and harmful gas, and the pump house is located 11 meters above the equalizing basin, causes the installation construction degree of difficulty of ultrasonic wave fluviograph great. The static pressure type liquid level meter is based on the principle that the static pressure of the liquid to be measured is proportional to the height of the liquid, and an isolated diffused silicon sensitive element or a ceramic capacitance pressure sensitive sensor is adopted to convert the static pressure into an electric signal, and then the electric signal is converted into a standard electric signal through temperature compensation and linear correction. The medium composition in the regulating reservoir is complex, and the liquid density fluctuates in real time, so that the static pressure type liquid level meter is not suitable for measuring the liquid level height in the regulating reservoir. The defects existing in the measurement of the liquid level height of the regulating tank by using the floating ball liquid level meter are mainly shown as follows: because the adjusting tank has more impurities, in the process of up-and-down movement of the floating ball, the gap between the floating ball and the connecting rod is easily blocked by the impurities, so that the up-and-down movement of the floating ball is blocked, and finally, the measurement error is larger.
