NYWL-L Turbine Flowmeter Working Principle
NYWL-L series turbine flowmeter is absorbed the advanced technology of flow meters at home and abroad after optimization design, with simple structure, lightweight, high accuracy, good reproducibility, responsive, easy to install and maintain the use of a new generation of turbine flowmeter, widely used in measuring closed pipeline with stainless steel 1CraNigTi, 2Cris and corundum Alc0a, hard alloy does not corrode. And no fibers, particles and other impurities, working temperature kinematic viscosity of less than 5 × 10-6m3 / s liquid, for kinematic viscosity greater than 5 × 10-6m² / s liquid, the flowmeter can be used after calibration of the real liquid. If the display instrument with special functions, can also be quantitative control, over-volume alarm, etc., is the ideal instrument for flow measurement and energy saving.
The instrumentation coefficient of the sensor is derived from the calibration of the flow calibration device, which does not ask the internal fluid mechanism of the sensor at all, the sensor as a black box, according to the input (flow) and output (frequency pulse signal) to determine its conversion coefficient, it is convenient for practical applications. However, it should be noted that this conversion factor (instrumentation factor) is conditional, its calibration conditions are reference conditions, if the use of deviation from this condition coefficients will change, the change depends on the type of sensor, pipe installation conditions and fluid physical parameters of the situation.
NYWL-L Turbine Flowmeter Design Feature
1. High accuracy, generally up to ± 1% R, ± 0.5% R, high-precision type up to ± 0.2% R.
2. Good repeatability, short-term repeatability of up to 0.05% ~ 0.2%, it is because of good repeatability, such as frequent calibration or online calibration can get very high accuracy, in the trade settlement is the preferred flowmeter.
3. Output pulse frequency signal, suitable for total measurement and computer connection, no zero point drift, strong anti-interference ability.
4. Can obtain a very high frequency signal (3 ~ 4kHz), strong signal resolution.
5. Wide range, medium and large diameter up to 1:20, small diameter of 1:10, compact and lightweight structure, easy installation and maintenance, large circulation capacity.
6. Applicable to high-pressure measurement, the meter body does not need to open the hole, easy to make high-pressure type instrument.
7. Special sensor types, can be designed according to the special needs of users for various types of special sensors, such as low-temperature type, bi-directional type, downhole type, sand mixing special type, etc.
8. Can be made into insertion type, suitable for large diameter measurement, small pressure loss, low price, can be removed without flow, easy to install and maintain.
