Sensor has a simple structure, lightweight, high precision, reproducibility good, responsive, easy installation and maintenance, which is widely used in petroleum, chemical, metallurgy, water, paper and other industries is an ideal flow metering and energy meter. Details I. Overview LWGY Series turbine flow sensors is to draw a new generation of turbine flow meter at home and abroad advanced technology and optimized design, it has a simple structure, lightweight, high precision, reproducibility good, responsive, easy installation and maintenance features flowmeters, widely used to measure the closed pipe and stainless steel 1Cr18Ni9Ti, 2Cr13 and corundum Al2O3, carbide not corrode, and no fibers, particles and other impurities, kinematic viscosity at operating temperature is less than 5 × 10-6m2 / s of liquid After use, the kinematic viscosity greater than 5 × 10-6m2 / s of liquid, solid liquid flow meter calibration. If the display instrument has a special function, can also be quantitative control, excessive alarm, etc., it is ideal for flow measurement and energy meter. Kind of turbine flow product itself does not have on-site display, only traffic signal in the form of pulses of remote output. Instrument inexpensive, high integration, small size, especially for the secondary display device, PLC, DCS and other control systems with the use of a computer. Second, product characteristics 1. High accuracy, usually up to ± 1% R, ± 0.5% R, high-precision up to ± 0.2% R; 2. good reproducibility, short-term repeatability of up to 0.05% to 0.2%. It is due to good reproducibility, such as frequent calibration or online high accuracy calibration available in the trade settlement is the preferred flow meter; 3. Output pulse frequency signal, suitable for the total measurement and connected to the computer , no zero drift, anti-jamming; 4. availability of a high frequency signal (3-4kHz), signal resolution and strong; 5. wide range of degrees, medium and large caliber up to 1:20, the small diameter of 1: 10; 6. Compact, lightweight, easy installation and maintenance, flow capacity; 7. The application of coercive measure, the meter body does not have to hole, easily made from the high-pressure type instrument; 8. special type of sensor types, according to the special needs designed for all kinds of special-type sensors, such as low temperature, two-way type, underground type, sand and other special type; 9. Insertion can be made for large diameter measurement, pressure loss, low price, time to drying out, easy installation and maintenance. Third, the basic parameters and technical performance 1.
