LWGY Compact Turbine Flow Meter

1、 Overview narrate, recount, state
LWGY Compact Turbine Flow MeterIt is a new generation of turbine flowmeter that has absorbed advanced technology from domestic and foreign flow meters and has been optimized for design. It has the characteristics of simple structure, lightweight, high accuracy, good reproducibility, sensitive response, and easy installation, maintenance, and use. It is widely used for measuring liquids in closed pipelines that do not corrode stainless steel 1Cr18Ni9Ti, 2Cr13, corundum AI2O3, and hard alloys, and have no impurities such as fibers or particles. The working temperature has a kinematic viscosity of less than 5 × 10-6m2/s. For liquids with a kinematic viscosity greater than 5 × 10-6m2/s, the flowmeter can be calibrated for real liquid before use If paired with display instruments with special functions, it can also perform quantitative control, over limit alarm, etc., making it an ideal instrument for flow measurement and energy conservation
2、 Product Features
1accuracyGenerally, it can reach ± 1% R and ± 0.5% R, and high-precision models can reach ± 0.2% R;

2Good repeatability, short-term repeatability can be achieved0.05%~0.2%, precisely due to its good repeatability, can be obtained through regular calibration or online calibrationFlow meters with high accuracy are preferred for trade settlement;

3Output pulse frequency signal, suitable for total measurement and computer connection, no zero drift, strong anti-interference ability;

4Can obtain high frequency signals（3~4kHz）， Strong signal resolution;

5Wide range, capable of reaching medium to large diameters1: 20, with a small caliber of 1:10;

6Compact and lightweight structure, easy installation and maintenance, and high circulation capacity;

7Suitable for high voltage measurement, there is no need to open holes on the instrument body, making it easy to make high voltage instruments;

8There are various types of specialized sensors that can be designed according to the specific needs of users, such as low-temperature, bidirectional, and downhole sensorsType, sand mixing special type, etc;

Can be made into an insertion type, suitable for measuring large diameters, with low pressure loss, low price, can be removed without interruption, and easy installation and maintenance.
IIILWGY Compact Turbine Flow MeterInstrument classification
According to the classification of instrument functions, the LWGY series turbine flowmeter can be divided into two categories, namely:
■ Turbine flow sensor/transmitter
Intelligent integrated turbine flowmeter
2. Function Description
■ Turbine flow sensor/transmitter
This type of turbine flow product itself does not have on-site display function, only transmitting and outputting flow signals remotely. Flow signals can be divided into pulse signals or current signals (4-20mA); The instrument is inexpensive, highly integrated, and compact in size, making it particularly suitable for use with computer control systems such as secondary displays, PLCs, and DCS.

LWGY Compact Turbine Flow MeterExquisite appearance, can choose to have a digital display.A new intelligent instrument integrating turbine flow sensor and display integration developed using advanced ultra-low power single-chip microcomputer technology, with dual row LCD on-site display, has obvious advantages such as compact structure, intuitive and clear reading, high reliability, no external power interference, lightning resistance, and low cost. The instrument has three-point correction of instrument coefficient, intelligent compensation of instrument coefficient nonlinearity, and can be corrected on site. High definition LCD display simultaneously displays instantaneous flow rate（4-digit significant digits) and cumulative traffic (8-digit significant digits, with reset function). Keep all valid data intact for 10 years after power failure.

This type of turbine flowmeter can choose explosion-proof products, with an explosion-proof rating of ExdIIBT6.

This type of turbine flowmeter can be classified according to the power supply method and whether it has remote signal outputLWGY - □ B type and LWGY - □ C type.
LWGY - □ B type: The power supply uses a 3.2V10AH lithium battery (which can operate continuously for more than 4 years); No signal output function.
LWGY - □ C type: The power supply adopts 24VDC external power supply, outputs 4-20mA standard two-wire current signal, and can add RS485 or HART communication according to different on-site needs.
