Smart Vortex Flowmeter FLVJ Series Intelligent Vortex flowmeter is mature and reliable sensing piezoelectric sensor technology, which according to conditions characteristic of demand can be velocity, flow (or temperature conditions, pressure testing to optimize one), fully reflects the today's high-tech mechatronics products and its price. The instrument data processing system using Microchip's MCU technology combined with modern microelectronic technology developed a highly reliable, high accuracy industrial flow measurement and control instruments. Cause dryness change widely used in closed conduits metering steam, gas and liquid media influence intelligent vortex flow meter measurement accuracy of pressure fluctuations around the pipe and meter vibration meter on the outlet side to the atmosphere meter straight pipe installation does not meet Require smart vortex flowmeter with intelligent all-digital circuit board - excellent vibration disturbance rejection performance 1, using the most advanced real-time RAGC AGC technology, SSP adaptive spectral filtering techniques, as long as there is a whirlpool on the work 2, no DIP Switches can be applied to various caliber gas, liquid vortex flow meter measuring Yunnan supply, frequency range 0.5Hz ~ 4KHz 3, ultra-high stability, technical stability than conventional 10 times more range than truly 15: 1 First, the vortex flow sensor Features: 1. Scale range of vortex flowmeters sensor range in a small range. An accuracy of 0.5 or higher. Measuring range increases Yunnan vortex flow meter principle, the accuracy decreases. For gas metering. Good sensor is 1.5 accuracy. Turndown ratio up to 1: (20-25), the flow rate of (3-75) m / s. Usually only 1 ratio sensor range: (8-10). 2. Repeatability speed meter verification provisions, each flow sensor to detect point three times, find the maximum difference. Take the full range of all test points (generally 5-6 points) The maximum difference of repeatability. Generally 0.2% and 0.3%. 3. Pressure Loss vortex flow sensor is very small pressure loss Yunnan vortex flow meter outlet, for example: when the saturated vapor pressure of 0.6MPa. Flow rate of 30m / s. Pressure loss 4kPa. Also with the smoothness of the inner wall of the relevant. 4. Simple stability of vortex flow sensor structure. No wear, sports, displacement components, good stability. After two test cycle (4 years), their accuracy, repeatability and meter factor can still be close to the factory index. 5. Maintenance mass confusion eddy current probe is to convert pressure into an electrical signal (frequency signal), the detection frequency signal amplifier board is an integral formation of the probe pulse, sent with the probe frequency equivalent to the indicator. Replace the detector amplifier board does not affect the measurement accuracy and other indicators. Even replacement of the probe in accordance with technical requirements under the premise, but also to ensure the technical specifications. No adjustment in the test cycle, any component calibration sensor. 6. Vibration vortex flow sensors is generated by the vibration frequency signal. In a strong vibration environment, vibration generated when the signal is greater than the fluid to generate a signal. Detection amplifier board is unable to eliminate vibration signal. The sensor can not be accurately measured, since the vibration of this sensor is still no flow frequency output. This is the biggest drawback vortex sensor.
