The LUGB vortex flowmeter is a high-precision, highly intelligent, and highly reliable flow instrument developed by our company based on modern international advanced technology. Can be used to measure the flow rate of fluids inside closed pipelines. It is widely used in the petroleum, chemical, metallurgical, thermal, papermaking, food and beverage industries. Measurement and control of superheated steam, saturated steam, compressed air, oxygen, nitrogen, natural gas, ammonia, biogas, etc., as well as water and other liquids (such as thermal oil, oil, alcohol, benzene liquids, etc.). Guangzhou Aoyi adopts advanced differential technology, combined with isolation, shielding, filtering and other measures, to overcome the problems of poor seismic resistance and small signal data disorder of similar products. It also adopts unique sensor packaging technology and protective measures to ensure the reliability of the product. There are two types of products: basic type and composite type. The basic type measures a single flow signal; The composite type can simultaneously measure temperature, pressure, and flow rate. Each type has a whole or split structure to adapt to different installation environments. Main features of vortex flowmeter: The measurement of flow rate is not affected by changes in fluid density, pressure, viscosity, and temperature within a certain Reynolds number range. The signal generated by the sensor is linearly related to the flow rate, and the measurement accuracy is high. 2. The detection element is not in contact with the medium, with stable performance, no zero drift, and long service life. 3. The sensor has no movable parts, a simple and sturdy structure, easy installation, and maintenance free. 4. Our company adopts advanced 4-axis machining center equipment to process flow meter body and vortex generator components, ensuring the machining accuracy, smoothness, and concentricity of the parts. By using high-precision positioning fixtures to weld the vortex generator of the flowmeter, the instrument coefficient uncertainty and repeatability of the flowmeter have achieved a high degree of consistency. 5. The piezoelectric crystal components for flow detection are sealed using the latest laser welding sealing technology, achieving an IP68 protection level for the flow detection probe. This effectively reduces signal attenuation caused by moisture in the piezoelectric crystal, greatly improving the lifespan of the flow detection probe and enabling the flow meter to operate stably in harsh, high-temperature, and humid environments for a long time. 6. Unique flow detection probe fixing method with shock-absorbing jacket inside, effectively isolating signal interference caused by pipeline mechanical vibration and fluid noise. 7. The flow transmitter adopts a differential dual channel charge amplifier to amplify the effective signal reasonably, and with the shock-absorbing design of the flow probe, it greatly eliminates pipeline vibration. Adopting the most advanced RAGC real-time automatic gain control+SPS adaptive spectrum filtering, signal frequency automatic tracking technology, and automatic attenuation of vibration noise at different frequencies by 100 times. 8. Double row LCD backlight display, capable of simultaneously displaying instantaneous, cumulative flow rate, current pressure, current temperature and other information. Built in, with a complete anti-interference multi-level protection circuit, it effectively eliminates on-site vibration and power frequency interference 9. Unique data backup and recovery design, the instrument can back up configuration information such as range before leaving the factory. When the user adjusts the instrument parameters on site and causes the instrument to malfunction, entering the password can restore it to the factory state
