Details 
 First, an overview 

 ZK-LWGY series turbine flow sensor flow meter is learned at home and abroad advanced technology optimized design, has a simple structure, compact, high accuracy, repeatability is good, responsive, easy installation and maintenance features such as a new generation of turbine flow meters, widely used to measure the closed pipe with stainless steel 1Cr18Ni9Ti, 2Cr13 and corundum Al2O3, lubricants vegetable oil Diesel Oil. .......... carbide and other oil products do not corrode, and no fibers, particles and other impurities, the working temperature kinematic viscosity of less than 5 × 10-6m2 / s of the liquid, the kinematic viscosity greater than 5 × 10-6m2 / s of liquid flow meter can be calibrated using real liquid . If the special features and display instrument package can also be a quantitative control, excessive alarm, flow measurement and energy is the ideal instrument. 

 Turbine flow products such pulse signal output type, output current signal type, on-site display type, etc., can be used to meet various requirements. Instrument inexpensive, high integration, small size, especially for the secondary display device and, PLC, DCS and other computer-controlled system used in conjunction. Series turbine flow meter is a smart one advanced ultra low power single-chip microprocessor technology developed by the turbine flow sensor and totalizer display integration of new smart meters, using two-row LCD display field, with a compact body, intuitive readings clear, reliable high, free from outside interference power, anti-lightning, low cost, significant advantages. Meter factor correction with three instruments, intelligent instruments compensate the nonlinear coefficient, and on-site correction. Turbine flowmeter are proof of such products, explosion-proof grade: ExdIIBT6. 

 Second, product characteristics 

 1 high-precision, generally up to ± 1% R, ± 0.5% R, high-precision up to ± 0.2% R; 

 2. Repeatable, short-term repeatability of up to 0.05% and 0.2%, is due to good reproducibility, such as frequent calibration or on-line high precision calibration available in the trade settlement is the preferred flow meter ; 

 3 for volume measurement and computer connection, no zero drift, anti-jamming; 

 4 available high-frequency signals (3-4kHz), signal discrimination ability; 

 5 degrees wide range, the large diameter of up to 1:20, the small diameter of 1:10; 

 6 compact and lightweight, convenient installation and maintenance, distribution capacity; 

 7. Suitable for high pressure measurement, instrumentation on the table without opening the body, made of high-pressure type instrument is easy; 

 8 special type of multi-sensor, can be designed according to the special needs for all types of special sensors, such as low temperature, two-way type, underground type, special type of sand, etc.; 

 9 can be made into the type, suitable for large-diameter measurements, pressure loss, low prices, from time to drying out, installation and maintenance.
