First, the vortex flow sensors features: 1. Scale range of vortex flowmeters sensor range in a small range. An accuracy of 0.5 or higher. Measuring range increases, 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 sensors pressure loss is very small, 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 member steam pipe flow meter retail, 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 signal direct steam pipe flow meter, the equivalent frequency probe sent to the display instrument. 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. What is the vortex flowmeter pipeline: Pipeline vortex flowmeter is a high accuracy steam pipe flow meter, simple installation, low maintenance, with extensive use of flow meters; product testing probe combination with optimized structure and special technology package original steam pipe flow meter, vibration superior performance; detecting element does not contact the media, no moving parts, low pressure loss, long life; intelligent integrated design, can live shows and instantaneous flow rate and cumulative flow meter factor.
