Irrigation water is essential for agriculture, lawns, gardening, etc., and water resources are increasingly expensive. Install flow measurement equipment to know how much water is being used. In the past, mechanical water flow meters have been widely used in irrigation, and mechanical flow meters have many inherent drawbacks. As a result, more and more digital water meters are being used in irrigation applications.
Ultrasonic flowmeter has the advantages of non-contact installation, no flow obstruction, no pressure loss, etc. It is suitable for flow detection of impure fluids with bubbles and impurity particles. In the field of farmland irrigation, the fluid is mixed with sediment and air bubbles and the flow measurement accuracy is limited, so it is proposed to apply the ultrasonic flowmeter to the flow measurement of farmland irrigation.
