SYJT Turbine Flowmeter

　　The SYJT turbine flowmeter is a high-precision instrument that measures fluid flow based on the principle of turbine rotation. The following is a detailed introduction to the turbine flowmeter of Shangyi:

　　1、 Working principle

　　The working principle of the turbine flowmeter is based on the principle of conservation of fluid momentum. When the measured fluid flows through the turbine flowmeter, the fluid impacts the turbine blades, causing the turbine to produce rotational motion. The rotational speed of the turbine is directly proportional to the average flow velocity of the fluid, therefore, by measuring the rotational speed of the turbine, the flow rate of the fluid can be derived. Specifically, the rotation of the turbine periodically cuts the magnetic field lines generated by the permanent magnet inside the casing, causing changes in the magnetic flux in the sensing coil. The periodic variation signal of this magnetic flux is then sent to the preamplifier for processing, converting it into a pulse signal proportional to the flow rate. These pulse signals are then sent to the unit conversion and flow accumulation circuit to obtain and display the accumulated flow value. At the same time, the pulse signal is also sent to the frequency current conversion circuit, which converts it into an analog current quantity and indicates the instantaneous flow value.

　　2、 Characteristics

　　High precision: The measurement accuracy of the upper turbine flowmeter can usually reach within ± 0.2% (the accuracy may vary depending on different models and measurement media, but generally higher), which can meet the needs of high-precision flow measurement.

　　Quick response: Its response time is extremely short, usually 0.01 seconds, and it can quickly reflect changes in traffic.

　　Large range ratio: The range ratio of the turbine flowmeter can reach 10:1, which can adapt to the measurement needs of different flow ranges.

　　Strong anti-interference ability: By using a magneto electric conversion device to convert the turbine speed into an electrical pulse signal, and amplifying and shaping it through a preamplifier, the anti-interference ability of the detection circuit is improved.

　　Simple structure: The structure of the turbine flowmeter is relatively simple, with few processed parts, light weight, and easy maintenance.

　　3、 Application scenarios

　　The SYJT turbine flowmeter has a wide range of applications in multiple fields and scenarios due to its high precision, fast response, and wide applicability. For example:

　　Petrochemical industry: used for flow measurement of liquid media such as crude oil and refined oil, as well as flow measurement of gases such as natural gas.

　　Water treatment industry: used to monitor and regulate the flow of water, ensuring the efficiency and effectiveness of water quality treatment.

　　Environmental monitoring field: used to monitor the emissions of pollutants such as wastewater and exhaust gas, providing data support for environmental decision-making.

　　Metallurgical industry: used to measure the flow rate of metal liquids such as molten iron and steel.

　　Food and beverage industry: used to measure the flow rate of various liquid raw materials and finished products, such as milk, juice, beer, etc.

　　Medical equipment: used for precise measurement of infusion flow, ensuring accurate input of drugs or nutrient solutions.

　　4、 Maintenance and Precautions

　　During use, installation, use, and maintenance should be strictly carried out in accordance with the operating procedures to ensure the measurement accuracy and reliability of the turbine flowmeter. Specific maintenance and precautions may include:

　　Regularly calibrate instruments to ensure measurement accuracy.

　　Check whether the turbine and sensing coils are damaged or worn, and replace them in a timely manner.

　　Clean the impurities and dirt inside the instrument to keep it clean and unobstructed.

　　Be careful to avoid excessive impact and vibration on the instrument to avoid affecting measurement accuracy.

　　In summary, the SYJT turbine flowmeter is a high-precision, fast response, and widely applicable flow measuring instrument that plays an important role in multiple fields and scenarios.
