Application of liquid level gauge in sewage treatment

When the liquid level difference exceeds the preset value, the operation of the grille is controlled to remove garbage, ensure normal water overflow, and reasonably reduce equipment wear. Correspond to the control program according to the measured value, automatically control the operation combination of the lift pump. In this way, the pump running state can be adjusted accurately and timely according to the amount of water from outside the plant, reducing equipment fatigue; at the same time, the human resources cost of the three shifts of the traditional pumping station can be cancelled. Lift pump operation control., all of which have the disadvantage that they cannot be monitored and displayed in real time.

Application of liquid level gauge in sewage treatment 1.. Traditional water flow measurement uses weir plates or Venturi flow grooves, etc. Grille operation control. The measuring tank of Langdong Sewage Treatment Plant adopts ultrasonic flowmeter combined with Venturi tank, which can display the flow rate and accumulated treatment volume in real time on the site and the host computer, so as to achieve the purpose of accurately measuring the treatment water volume and providing real-time flow rate for operation management. The level difference between the front and back of the grid reflects the degree of grid blockage and is transmitted to the PLC controller for analysis and calculation.

The coarse grid and the fine grid are each equipped with a magnetic flap liquid level gauge. In order to realize the automatic control of the water inlet lift pump, two magnetic turnover column liquid level gauges were installed at the water inlet pump well to measure the water level of the pump well, and transmitted to the PLC controller and the upper computer for system analysis in real time. Butterfly Valve Manufacturers Accurately and timely grasping the amount of water inflow has an important role in process control and improving the capacity of the sewage plant to resist hydraulic load impact.2. For the operation and management of sewage treatment plants, water volume is an important control parameter
