What is the measurement accuracy of liquid turbine flowmeter?

High accuracy, generally ± 0.25% R - ± 0.5% R for liquids, and up to ± 0.15% R for high-precision types; while for gases, it is generally ± 1% R - ± 1.5% R, and for special types, it is ± 0.5% R - ± 1% R. Among all flow meters, it is the most accurate. 2) Good repeatability, short-term repeatability can reach 0.05% -0.2%, precisely because of its good repeatability, such as frequent calibration or online calibration can achieve extremely high accuracy, it is the preferred flowmeter in trade settlement. 3) Output pulse frequency signal, suitable for total measurement and computer connection, no zero drift, strong anti-interference ability. 4) High frequency signals (3-4kHz) can be obtained with strong signal resolution. 5) Wide range, with a medium to large caliber of up to 40:1-10:1 and a small caliber of 6:1 or 5:1. 6) Compact and lightweight structure, easy installation and maintenance, and high circulation capacity. 7) Suitable for high voltage measurement, there is no need to open holes on the instrument body, making it easy to make high voltage instruments. 8) There are various types of specialized sensors that can be designed according to the specific needs of users, such as low-temperature nuclear reactors, bidirectional sensors, downhole sensors, sand mixing sensors, etc. 9) Can be made into an insertion type, suitable for measuring large diameters, with low pressure loss, low price, can be removed without interruption, and easy installation and maintenance. 10) It is difficult to maintain calibration characteristics for a long time and requires regular calibration. For non lubricating liquids, which contain suspended solids or abrasives th

at cause bearing wear and jamming, their applicability is limited. The use of wear-resistant hard alloy shafts and bearings has improved the situation. For trade storage, transportation, and high-precision measurement of collapsed stools, it is best to equip them with on-site calibration equipment that can be regularly calibrated to maintain their characteristics. 11) General liquid turbine flow meters are not suitable for high viscosity media (except for high viscosity types). As the viscosity increases, the measured line value of the flow meter increases, the range decreases, and the linearity deteriorates. 12) The physical properties of fluids (density, viscosity) have a significant impact on the characteristics of instruments. Gas flow meters are easily affected by density, while liquid flow meters are sensitive to changes in viscosity. Due to the close relationship between density and viscosity with temperature, rubber, and pressure, temperature and pressure fluctuations are inevitable on site. Compensation measures should be taken based on their impact on accuracy in order to maintain high measurement accuracy. 13) The liquid turbine flowmeter is greatly affected by the distortion of the incoming flow velocity distribution and the rotating flow. A long straight pipe section needs to be installed on the upstream and downstream sides of the sensor. If the installation space is limited, a flow regulator (rectifier) can be installed to shorten the length of the straight pipe section. 14) Not suitable for measuring pulsating and mixed flow.
