　　Gas turbine flowmeterMainly used for flow measurement of media fluids such as air, nitrogen, oxygen, hydrogen, biogas, natural gas, and steam in industrial pipelines. When measuring volumetric flow under working conditions, it is almost unaffected by parameters such as fluid density, pressure, temperature, and viscosity. There are no moving machine parts, high reliability, and low maintenance. The instrument parameters can remain stable for a long time. The gas vortex flowmeter uses pressure stress sensors, has high reliability, and can operate within a working temperature range of -20 to 250 degrees. It has analog standard signal and digital pulse signal output, making it easy to use with digital systems such as computers, and is a relatively advanced and ideal flowmeter.

The pulse frequency signal output from the gas turbine flowmeter is not affected by changes in fluid properties and components. In other words, the instrument coefficient of the gas turbine flowmeter is only related to the shape and size of the vortex generator and pipeline within a specific Reynolds number range. However, as a flowmeter, when detecting mass flow in material balance and energy measurement, the output signal of the flowmeter must simultaneously monitor volumetric flow and fluid density, as fluid properties and components directly affect flow measurement. The gas vortex street flowmeter is a new type of flowmeter that measures closed pipe fluid flow based on the Kármán vortex street principle. Due to its strong adaptability to media, it can directly measure the volumetric flow of steam, air, gas, water, and liquids under working conditions without temperature and pressure compensation. Temperature and pressure sensors can measure standard volumetric flow and mass flow, making it an ideal alternative to throttling flowmeters.

To improve the high temperature and vibration resistance of gases,Gas turbine flowmeterwith its unique structure and material selection, the sensor can be used under harsh conditions of high temperature (350 degrees) and strong vibration (1g). In practical applications, the large flow is often far below the upper limit of the instrument, and as the load changes, the small flow is often below the lower limit of the instrument, causing the instrument to be ineffective in its working range. To solve this problem, the diameter is generally reduced at the measurement point to increase the flow rate at the measurement point, and a small-diameter instrument is selected for convenience in measurement. However, there must be a straight length of more than 15D between the transistor and the instrument.

For ease of use, the gas turbine flowmeter provides a battery-powered field display. The gas vortex flowmeter adopts advanced micro-power technology, and the gas turbine flowmeter powered by lithium batteries can operate continuously for more than a year, reducing the purchase and installation costs of cables and display instruments. It can display instantaneous flow, cumulative flow, etc. The temperature-compensated vortex flowmeter also includes a temperature sensor, which can directly measure the temperature of saturated steam, calculate pressure, and display the mass flow of saturated steam. The temperature and pressure compensated model has temperature and pressure sensors, which can directly measure the temperature and pressure of the gas medium through gas flow measurement, displaying the standard volumetric flow of the gas.
