River water flow velocity principle and installation method of acoustic doppler flowmeter

Abstract: the river water flow velocity of the principle of acoustic doppler flowmeter and installation method of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Natural river water flood control is related to people's safety and social stability, flow monitoring is an important part of flood control. Small and medium-sized rivers flood control hydrological monitoring can real-time understanding of river water, is of great significance for flood control. At the same time, its saving water and regulating regional stingy. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the river water flow velocity of acoustic doppler flowmeter principle and installation method of this article for details. Natural river water flood control is related to people's safety and social stability, flow monitoring is an important part of flood control. Small and medium-sized rivers flood control hydrological monitoring can real-time understanding of river water, is of great significance for flood control. At the same time, the saving water and adjust the function of regional microclimate and countries pay more attention to the rational development and utilization of water resources, so the timely, accurate and comprehensive to reflect the current state of the small and medium-sized rivers water is particularly important. In this case, the provincial hydrology bureau in key river several hydrographic office installed DX - LSX - 1 doppler ultrasonic flowmeter, the province mainly small and medium-sized rivers flow monitoring, achieve 24-hour online traffic monitoring, monitoring of flood season changing flow, to master basic information data, provide the basis for flood control and drainage. Doppler ultrasonic flowmeter is a kind of measuring instrument for flow velocity and flow in natural water bodies. It doesn't need to cut the pipe and install like electromagnetic flowmeter tube type sensor, also do not need to use the closure device, not to mention the installation of fixed weir tank to control the flow of exports from fixed. Just in the direction of flow at a fixed, when the water flow more than 2 cm, can begin to flow velocity, flow rate and water level comprehensive testing. dx - LSX - 1 the principle of doppler ultrasonic flowmeter: doppler ultrasonic flowmeter speed area method is used to measure flow, which consists of a water meter and a flow sensor. , when using the channel type and parameters of the prior input controller, the controller can use water to overflow area of conversion, the amount of water can be made of the overflow area & times; Flow calculation. Doppler ultrasonic flowmeter product features: low wide range: 0. 05m/s( Velocity) Low resolution (up to 1 mm/SEC Velocity) Low response time is long, broke the past take a long time to get traffic and traffic situation, the measurement will be refreshed from time to time. Low velocity of flow area method used throughout pipe and not all, are free to set section water relations. Low internal high precision temperature sensor can be used for temperature measurement and sound velocity compensation. Low hydrodynamic hull design have little impact on flow state, does not affect the accuracy of measurement. Low corrosion protection shell design, can work under the bad environment for a long time. To provide the instantaneous flow values and cumulative flow value. Low no mechanical moving parts, no sediment jam or aquatic plants and sundry winding and so on. It is the most suitable for high content of suspended sediment and aquatic plants such as river containing qualitative measurement. Linear measurement, the factory calibration, use for a long time do not need to be calibrated. Equipped with data receiving software, can read real-time data and accumulated data. Technical parameters: velocity, measuring range: 0. Precision of 5 m/s: 1. 0% of 1 cm/s resolution: 1 mm/SEC depth: measuring range: 0 m - 5m( Can be set higher) Accuracy: 1 cm resolution: 1 mm temperature: measuring range: - 10℃- 60 ℃ accuracy: 0. 5 ℃, resolution: 0. 1 ℃ flow: measuring range: 0. 001 - meters per hour 99999999 meters/hour ( According to section) Accuracy: 3% ( Depends on the cross section flow type) Resolution: 0. 0001 m/s power supply: DC 10 v - 24 v working voltage: 12 v is less than 0. 1 a output signal: RS485 ( 网络通讯协议, RTU) Protection grade: IP68 working temperature: 0 ℃ - 60℃( Don't freeze) Storage temperature: - 10℃- 70 ℃ equipment material: gray PVC doppler flowmeter installation in this case, the DX - LSX - 1 doppler ultrasonic flowmeter for 24 hours online real-time measurement, installed in a typical stable position of natural river hydrological station. In addition to the final traffic data, can also obtain discharge and water level data at the same time, easy to understand and internal flow, the discharge of rivers and always keep a stable working state, to help users to monitor rivers flow. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
