　　Turbine flow meterIt is a new type of velocity-type instrument, which has advantages such as high accuracy, good repeatability, simple structure, high pressure resistance, wide measurement range, small size, light weight, low pressure loss, long service life, simple operation, and convenient maintenance. The temperature and pressure compensated instrument can integrate flow, temperature, and pressure detection functions. The turbine flow meter can perform automatic compensation for temperature, pressure, and compression factor, making it an ideal gas flow detection instrument for gas measurement in industries such as petroleum, chemical, electric power, metallurgy, industrial boilers, and for measuring the volume flow and total amount of low-viscosity gases in closed pipelines of urban natural gas and gas pressure regulating stations.

Application characteristics of turbine flow meters:

　　1.Turbine flow meterIt is a precision flow measurement instrument that can be used to measure the flow and total amount of liquids when paired with corresponding flow accumulation instruments. It is widely used in measurement and control systems in fields such as petroleum, chemical, metallurgy, and scientific research. Turbine flow sensors equipped with sanitary connections can be applied in the pharmaceutical industry.

2. The integrated turbine flow meter structure is designed to be explosion-proof and can display total flow, instantaneous flow, and flow fullness percentage. The battery uses a long-lasting lithium battery, with a single-function accumulation meter battery life of over 5 years, and a multi-function display meter battery life of over 12 months.

3. The integrated display can show many flow units, including cubic meters, gallons, liters, standard cubic meters, and standard liters. It can set fixed pressure and temperature parameters to compensate for gases, and can be used for fixed compensation accumulation in cases where pressure and temperature parameters do not vary significantly.

　　4.Turbine flow meterThe sensor outputs a sine wave signal, which needs to be shaped into a square wave using a shaping circuit, and then connected to the IO port of a microcontroller for pulse counting, where flow is proportional to the pulse count.

What is the working principle of the turbine flow meter?

The working principle of the turbine flow meter is that when the fluid flows through the sensor housing, the angle between the blades of the impeller and the flow direction causes the fluid's impact to generate a torque on the blades. After overcoming the friction torque and fluid resistance, the blades rotate. When the torque is balanced, the rotation speed stabilizes, and under certain conditions, the rotation speed is proportional to the flow rate. Since the blades have magnetic properties, they are in the magnetic field of the signal detector, and the rotating blades cut through the magnetic lines of force, periodically changing the magnetic flux in the coil, which induces an electrical pulse signal at both ends of the coil. This signal is amplified and shaped by an amplifier, forming a continuous rectangular pulse wave with a certain amplitude, which can be transmitted to a display instrument to show the instantaneous flow and cumulative amount of the fluid.

To ensure the long-term normal operation of the gas turbine flow meter, it is necessary to regularly check the operating status of the flow meter, perform maintenance work, and promptly eliminate any problems found.
