[0002] According to the requirements of the produced water treatment process, oilfield gathering and transportation stations need to set up sewage and sludge pools for the collection of sewage and sludge; for pure sewage pools, top-mounted float level gauges are used to detect the liquid level. Based on the principle that the float floats up and down with the sewage liquid level, the sewage liquid level height is measured in real time, and the detected data is uploaded to the station control system for real-time monitoring and high and low liquid level alarms. With the requirements of digitalization and unmanned operation of the station, the sludge interface height of the sewage and sludge pool also needs to be monitored, and the sewage and sludge lift pumps are remotely started and stopped according to the monitoring signals to achieve digital monitoring and remote operation.
