1. What parameters do you need to know when selecting an ultrasonic flowmeter? Hello, KNKE, a manufacturer of ultrasonic flowmeters imported from the United States, is pleased to answer your question. In general, the on-site parameters that the manufacturer needs to provide for the selection of ultrasonic flow meters include:
1. Type of measuring medium
2. Temperature, turbidity, and corrosiveness of the medium
3. Nominal pressure
4. Size of flow rate (flow velocity)
5. Diameter and material of the pipeline. When selecting ultrasonic flow meters, the customers own required instrument performance parameters include:
1. Sensor installation method: external clamp, insertion type, pipe section type
2. Amplifier form: power supply, output signal (current, pulse, communication, relay)
3. Yes No If you have any questions or uncertainties regarding the selection of ultrasonic flow meters, please feel free to contact KNKE customer service at any time and we will help you solve them.
2. Introduction to Opening HD580
Opening HD580 is an industrial grade ultrasonic flowmeter with stable performance, used for measuring liquid flow, widely used in industries such as chemical, power, and water treatment. Its advantages are non-contact measurement, high precision, and wide range adaptation.
.1. Core technical parameters: 1) The measurement principle adopts the ultrasonic time difference method, which calculates the flow velocity by the time difference between the transmission and reception of ultrasonic waves in the liquid, without contacting the medium, and can avoid the risk of corrosion or pollution.
. 2) Under standard operating conditions, the accuracy can reach ± 0.5%~± 1%, with a repeatability of ± 0.2%, which can meet the precise measurement needs of industrial sites. 3) Supports various liquids such as water, sewage, petroleum, chemical solutions, etc., suitable for pipe diameters ranging from DN15 to DN6000mm, capable of handling large-diameter pipeline measurements. 4) Protection level IP65, working temperature -20 ℃~+160 ℃, suitable for extreme working conditions, with anti-interference ability, can operate stably in industrial sites with complex electromagnetic environments.2. Functional Features: 1) Fixed on the outer wall of the pipeline by an external clamp sensor, without cutting the pipeline or stopping production, easy to install and maintain, and can reduce engineering costs.
. 2) Equipped with RS4855, Modbus and other communication interfaces, supporting integration with PLC and SCADA systems, enabling real-time data upload and remote monitoring. 3) Equipped with built-in sensor fault detection and signal strength analysis functions, it can automatically prompt abnormalities and reduce maintenance workload. 4) The flow velocity measurement range is 0.01m/s~32m/s, covering small to large flow scenarios and adapting to different working conditions. III. Typical Application Scenarios 1) Measuring the flow rate of corrosive liquids and high viscosity media in the chemical industry can avoid the risk of leakage caused by pipeline openings. 2) Monitor the flow of boiler feedwater and cooling water in the power system to ensure the safe operation of power generation equipment. 3) The flow measurement used in water treatment engineering for municipal water supply and sewage treatment plants meets the requirements of environmental monitoring.
