1. Is the measurement range unit of gas turbine flowmeter standard gas?

The measurement tolerance range unit of gas turbine flowmeter is usually the gas volume unit under standard conditions, which belongs to the measurement caliber corresponding to standard gas..

1. General Measurement Rules 1 In domestic industrial scenarios, the mainstream labeling unit for gas turbine flow meters is Nm ³ (standard cubic meter), corresponding to a standard state of 0 ℃ and an absolute pressure of 101.325kPa; Some foreign trade or specific projects will adopt the standard state of 20 ℃ and 101.325kPa, with the unit marked as m ³ (20 ℃)

2. These units essentially convert the gas volume under actual working conditions into the volume under standard conditions, unify the measuring caliber, avoid measurement data incomparability caused by temperature and pressure fluctuations, and meet the regulatory requirements of energy measurement and trade settlement.

II. Exception to Special Working Conditions 1 The Muhui simple gas turbine flowmeter, which is only used for on-site temporary monitoring of working conditions, will directly label the volume flow rate under actual working conditions in meters (working conditions), but will clearly indicate the "working condition volume" to distinguish it from the standard volume unit. 2. For mandatory calibration scenarios involving trade settlement, standard volume units must be used, in accordance with national measurement standards such as GB 17167-2022 "General Rules for the Equipping and Management of Energy Measuring Instruments for Energy using Units".

2. What is a gas turbine flowmeter?

Gas vortex flow meter is mainly used for measuring the flo

w rate of medium fluids such as air, nitrogen, oxygen, hydrogen, biogas, natural gas, steam, etc. in industrial pipelines. When measuring the volumetric flow rate under working conditions, it is almost not affected by parameters such as fluid density, pressure, temperature, viscosity, etc. No movable mechanical parts, therefore high reliability and low maintenance. The instrument parameters can be stable for a long time. The gas vortex flowmeter adopts a piezoelectric stress sensor, which has high reliability and can operate within the working temperature range of -20 ℃ to+250 ℃. It has both analog standard signals and digital pulse signal outputs, making it easy to use in conjunction with digital systems such as computers. It is a relatively advanced and ideal flow meter. The pulse frequency signal output by gas vortex flowmeter is not affected by fluid properties and composition changes, that is, the instrument coefficient is only related to the shape and size of the vortex generator and pipeline within a certain Reynolds number range. However, as a flowmeter in material balance and energy measurement, it is necessary to detect mass flow rate. At this time, the output signal of the flowmeter should simultaneously monitor volume flow rate and fluid density. Fluid properties and components still have a direct impact on flow measurement. The gas vortex flowmeter is a new type of flowmeter that measures fluid flow in closed pipelines based on the Karman vortex principle. Due to its excellent adaptability to media, it can directly measure the volumetric flow rate of steam, air, gas, water, and liquid without temperature and pressure compensation. Equipped with temperature and pressure sensors, it can measure the volumetric
