Application of Level Gauge in Sewage Treatment
1, grille operation control. Coarse grille, fine grille each installed a magnetic flap level gauge, through the grille before and after the level difference to reflect the grille blockage, and transmitted to the PLC controller for analysis and calculation. When the liquid level difference exceeds the preset value, control the grille operation, remove the trash, protect the normal water, and reasonably reduce the equipment wear.
2, improve pump operation control. In order to realize the automatic control of water inlet pump, 2 magnetic turn-on level gauges were installed in the inlet pump well to measure the water level of the pump well and transmit it to the PLC controller and host computer in real time for system analysis. According to the measured value corresponding to the control program, automatic control lift pump operation combination. This can be based on the amount of water outside the factory accurate and timely adjustment of pump operation, reduce equipment fatigue; at the same time to cancel the traditional pumping station three shifts down the human resources
3, flow and capacity of real-time glass tube level gauge monitoring. For the operation of sewage treatment plant management, water is an important control parameters. Accurate and timely grasp of influent, process control and improve the ability of sewage treatment plant to withstand the impact of hydraulic load plays an important role. The traditional water measurement using weir plate or venturi flow slot, there are not real-time monitoring, real-time display shortcomings. Langdong Wastewater Treatment Plant metering tank with ultrasonic flowmeter combined with Venturi trough in the field and the host computer real-time display traffic and total processing capacity, to achieve accurate measurement of water treatment, as well as to provide real-time traffic management purposes.
