1、 High precision measurement

1. Wide range ratio
   • Gas flow meters can cover a wide range of flow measurements (such as 1:50 to 1:100), adapt to different operating conditions, and reduce the frequency of instrument replacement.
   • ExampleThermal mass flow meters can maintain high accuracy at low flow rates (such as a few milliliters per minute) to high flow rates (such as hundreds of cubic meters per hour).
2. Low flow sensitivity
   • Thermal and vortex street types are sensitive to small flow changes and are suitable for leak detection, laboratory analysis, and other scenarios.
   • ExampleThe thermal flowmeter can detect trace gas flow at 0.1 standard liters per minute (SLM).
3. Strong anti-interference ability
   • Using digital signal processing technology to effectively filter out interference such as vibration and noise, ensuring measurement stability.
   • ExampleVortex flowmeter eliminates the influence of pipeline vibration on signals through spectrum analysis technology.

2、 Multi functional integration

1. Temperature/pressure compensation
   • Integrated temperature and pressure sensors, automatically correcting changes in gas density, directly outputting standard volumetric or mass flow rates without the need for additional calculations.
   • Application scenariosMeasurement of natural gas trade and analysis of compressed air energy consumption.
2. Bidirectional flow measurement
   • Supports forward and reverse gas flow detection, suitable for process flows that require bidirectional control (such as gas turbine intake/exhaust).
   • ExampleTurbine flow meters achieve flow direction recognition through bidirectional pulse signals.
3. Multi parameter output
   • Simultaneously providing data such as flow rate, temperature, pressure, etc., supporting communication protocols such as Modbus, HART, Profibus, etc., for easy system integration.
   • Application scenariosData acquisition and monitoring (SCADA) in industrial automation systems.

3、 Strong adaptability

1. Wide compatibility of media
   • It can measure various gases (such as air, nitrogen, oxygen, natural gas, biogas, etc.), and some models support corrosive gases (such as chlorine and ammonia).
   • Material SelectionThe sensor is made of corrosion-resistant materials such as 316L stainless steel and Hastelloy to extend its service life.
2. environmental adaptability
   • temperature rangeWorking temperature can reach -40 ℃ to 200 ℃, suitable forharshenvironment
   • pressure ratingThe pressure resistant design covers vacuum to high pressure (such as 40MPa) to meet different pressure conditions.
   • Protection levelIP65/IP67 protection level, dustproof and waterproof, suitable for outdoor or humid environments.
3. Installation flexibility
   • pipeline-styleDirectly installed on pipelines, suitable for large-diameter flow measurement (such as DN100 and above).
   • plug-inBy inserting a probe for measurement, there is no need to cut off the pipeline, making it easy to retrofit and install.
   • portableBattery powered, mobile measurement, suitable for temporary testing or on-site calibration.

4、 Intelligence and ease of use

1. Self diagnostic function
   • Real time monitoring of sensor status, circuit faults, etc., using LED indicator lights or display screens to indicate abnormalities and shorten maintenance time.
   • ExampleMass flow meters can detect zero drift and automatically calibrate.
2. Remote operation and configuration
   • Support remote adjustment of parameters and viewing of data through mobile apps, web pages, or upper computer software to achieve unmanned management.
   • Application scenariosDistributed energy stations and remote monitoring systems.
3. Data recording and export
   • The built-in memory can record historical data (such as traffic trends and alarm events), and supports USB or wireless export for easy analysis.
   • ExampleTurbine flow meters can store minute level data for more than 30 days.
