I. Overview JY-LWGY Series turbine flow sensor is to draw a new generation of turbine flow meter at home and abroad advanced technology and optimized design, has a simple structure, lightweight, high precision, reproducibility is good, responsive, easy installation and maintenance features flowmeter, widely used to measure the closed pipe and stainless steel 1Cr18Ni9Ti, 2Cr13 and corundum Al2O3, carbide corrode, and no fibers, particles and other impurities, the kinematic viscosity at operating temperature is less than 5 × 10-6m2 / s liquid after use, for a kinematic viscosity greater than 5 × 10-6m2 / s of the liquid, a solid solution can be calibrated flowmeter. If the display instrument with special features, can also be quantitative control, excessive alarm, etc., is an ideal flow metering and energy meter class turbine flowmeter are explosion-proof products, explosion-proof grade:.. ExdIIBT6 suitable lubricants Vegetable oil Diesel Oil. resid. kerosene oil. gasoline heavy oil. fuel oil. HTF Crude light oil. insulating oil hydraulic oil. and other oil products .......... kind of turbine flow product has a pulse signal output type, current output type, field display type, etc., can meet a variety of requirements. 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, generally 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 trade settlement is the preferred flow meter; 3. suitable for the measurement of total and connected to the computer, no zero drift, jamming; 4. availability of high frequency signals (3-4kHz), signal resolution and strong; 5. wide range of degrees, medium and large caliber up to 1:20, small caliber 1:10; 6. Structure Compact and lightweight, easy installation and maintenance, flow capacity; 7. apply high voltage measurement, the meter body does not have to cut, easy to type instrument made of high pressure; 8. special type of sensor types, can be designed according to the special needs of all kinds of special type sensors, such as low temperature, bi-directional, underground type, sand and other special type; 9. Insertion can be made suitable for large diameter measurement, pressure loss, low price, do not remove the drying, easy installation and maintenance. Third, the measurement range and working pressure gauge diameter (mm) normal flow range (m3 / h) extended flow range (m3 / h) withstand pressure (MPa) DN4 0.04 ~ 0.25 0.04 ~ 0.4 6.3 DN6 0.1 ~ 0.6 0.06 ~ 0.6 6.3 DN10 0.2 ~ 1.2 0.15 ~ 1.5 6.3 DN15 0.6 ~ 6 0.4 ~ 8 6.3 2.5 (flange) DN20 0.8 ~ 8 0.45 ~ 9 6.3 2.5 (flange) DN25 1 ~ 10 0.5 ~ 10 6.3 2.5 (flange) DN32 1.5 ~ 15 0.8 15 6.3 2.5 (flange) DN40 2 ~ 20 1 ~ 20 6.3 2.5 (flange) DN50 4 ~ 40 2 ~ 40 2.5 (flange) DN65 7 ~ 70 4 ~ 70 2.5 (flange) DN80 10 ~ 1005 - 100 2.5 (flange) DN100 20 ~ 200 10 ~ 200 2.5 (flange) DN125 25 ~ 250 13 ~ 250 1.6 (flange) DN150 30 ~ 300 15 ~ 300 1.6 (flange) DN200 80 ~ 800 40 800 1.6 (flange)
