The ACF-1WLB integrated intelligent plug-in gas flowmeter (Velbar flowmeter) has a simple structure, no movable parts, stable and reliable long-term use, and high accuracy. High standardization and good linearity. It can directly measure the flow rate of various fluids in pipelines. It has the characteristics of easy installation, low pressure loss, high strength, no wear and tear, and no leakage, making it an ideal product to replace orifice flow meters. Weiliba can be widely used for flow measurement of blast furnace gas, compressed air, steam, and gas in industrial and mining enterprises.
1. It can measure multiple media, has a wide range of applications, high accuracy, and large range ratio;
2. The probe pressure hole is inherently anti blocking, with stable measurement signals and minimal fluctuations;
3. The pipeline has low permanent pressure loss, low installation cost, and is basically maintenance free;
4. Simple structure, safe and reliable, long service life, suitable for single well natural gas and coalbed methane measurement;
5. Resistant to high and low temperatures, high pressure, capable of measuring gases, liquids, and vapors, with a wide range of applications;
6. Simultaneously display cumulative flow rate, instantaneous flow rate, pressure, temperature, and differential pressure;
7. Standard RS485 communication interface, and configurable (4~20) mA standard current signal output for any variable.
