1. What is the unit of ultrasonic flowmeter for water? Ultrasonic flowmeter is an instrument used to measure the flow rate of liquids by emitting ultrasonic waves to measure the flow rate and velocity of liquids. For water, the unit of ultrasonic flowmeter is usually cubic meters per hour (m ³/h) or cubic meters per second (m ³/s). The working principle of ultrasonic flowmeter is to measure the flow rate by utilizing the relationship between the speed of ultrasonic propagation in liquid and the liquid flow velocity. When the ultrasonic transmitter emits ultrasonic waves into the liquid, the ultrasonic waves propagate in the liquid and are received by the receiver. Based on the time and distance of ultrasonic propagation in liquid, the flow velocity and flow rate of the liquid can be calculated. Ultrasonic flow meters have the advantages of high precision measurement, fast response speed, and are not easily affected by the properties of liquid macroligands and temperature. Therefore, they are widely used for flow measurement in industries such as water treatment, chemical, petroleum, and food. In the water treatment industry, ultrasonic flow meters are commonly used to measure the flow rate of liquids such as tap water, sewage, and industrial wastewater to ensure that water supply and discharge meet standards.

2. Application of Ultrasonic Flowmeters in Water Injection Wells - Ultrasonic Flow Meter Factory

Ultrasonic flow meters are mainly used for layer testing in water injection wells, achieving efficient and safe flow monitoring through non-contact measurement, optimizing water injection schemes, and improving oilfield recovery.

1. Technical characteristics of ultrasonic flowmeter The measurement principle is based on the ultrasonic phase difference method, which calculates the fluid flow velocity by the time difference or phase difference between the transmission and reception of ultrasonic signals, and combines it with the pipeline cross-sectional area to obtain the flow rate. Its non-contact measurement method does not require sealing, avoiding test failures caused by seal damage or instrument obstruction or jamming in traditional flow meters. The advantages of the instrument structure are non current collecting design: it can be freely moved to any depth for stopping point testing, supports up or down testing, and optimizes the testing process. Multi parameter synchronous monitoring: integrating pressure and temperature sensors to test layered flow while obtaining water injection pressure and temperature data, providing comprehensive basis for data analysis. Adapt to complex well conditions: not limited by the pipe structure, suitable for deep wells, deviated wells, and multi-layer injection wells. Technical indicators have improved the success rate of testing: from 60% using conventional methods to over 95%, significantly reducing repetitive tasks. Data accuracy: The wellhead stopping point test can be compared with the surface water meter measurement, enhancing the credibility of the data and significantly improving the pass rate of the testing layer. Safety: Avoid instrument jamming and reduce the risk of underground operations.
