Problems solved by technology

[0002] At present, the indirect measurement method of agricultural water used by rural drainage and irrigation stations to indirectly measure the water supply of drainage and irrigation stations according to the conversion relationship between electricity and water will have large errors, especially when the pump is operating at full load and light load, and the voltage is high and low. The error will be larger, and if the water pump is idling, it will be even more inaccurate
