Water Flowmeter DN4 Intelligent Screw Thread Display Liquid Turbine Flowmeter
304 Stainless Steel
OEM & ODM
LWGY series turbine flowmeter is a new generation of turbine flowmeters which has absorbed the advanced technology of flow meter at home and abroad,and is manufactured according to JB/9246-199 standard. It has the characteristics of simple structure, light weight, high precision, good reproducibility, high responsiveness, easy installation and maintenance. It is widely used to measure the liquid in closed pipeline. The liquid does not corrode stainless steel 1cr18Ni9Ti, 2Cr13 and corundum AI203 cemented carbide, and has no impurities such as fiber particles. The kinematic viscosity at working temperature is less than 5×10-6m2/s.For liquids with a kinematic viscosity greater than 5 × 10 m / s, the flow meter can be used after real liquid calibration.If it is matched with a display instrument with special functions, it can also perform quantitative control, excess alarm, etc, which is an ideal meter for flow metering and energy saving. 1. High-definition LCD display 2. Three-key parameter setting and debugging 3.5-segment polyline correction function for non-linear signals 4. Linear current output 5. Frequency pulse output: DC power can be used to supply power to the pulse output circuit. At this time, the meter can convert the mV pulse signal output by the turbine sensor into a standard TTL pulse,which can be used for linear signal users debugging. 6.LWGY-C type: 2AVDC external power supply is used for the power supply, and outputs 4-20mA standard two-wire current signal, and HART communication or RS485 communication function can be increased according to different site needs.
1.High precision, generally up to ±1%R, ±0.5%R, and high precision type can be up to ±0.2%R; 2.Good repeatability with short-term repeatability of 0.05%-0.2%. Due to good repeatability, such as frequent calibration or online calibration, it can get very high precision,which is the preferred flow meter in trade settlement; 3.Output pulse frequency signal, it is suitable for total metering and connected with computer, without zero drift, and with strong anti-interference ability; 4.It can obtainHigh frequency signal (3~4kHz) with strong signal resolution; 5.The range of medium and large caliber can reach 1:20, and the range of small caliber is 1:10; 6.It has the characteristics of compact structure, light weight, convenient installation and maintenance, and large circulation capacity; 7.It is suitable for high-pressure measurement, no need to open holes on the meter body, easy to make high-pressure type instrument; 8.It has many special sensor types, which can be designed into various types of special sensors according to the special needs of users, such as low temperature type, two-way type, downhole type, sand mixing type, etc. 9.It can be made into plug-in type, suitable for large caliber measurement, with low pressure loss, low price, continuous flow, and easy installation and maintenance.
