Abstracts:
LWGY series turbine flow meter is a new generation kind of flow meter that absorbed the
advanced technologies of flow meter at home and abroad,been optimized designed to
have so many characteristics, such as simple structure, light weight, high precision,good
reiteration,sensitive reaction,easy installation and using.
Features:
1) High accuracy
2) Good repeatability, can reach 0.05%-0.2% in short term,
3) High frequency signal(3-4kHz),strong signal resolution;
4) Wide range, middle and big diameter can reach 1:20, and small diameter can reach 1:10;
Electrical Specification
Power supply:external power supply--24VDC,apply to pulse output,4-20mAoutput and RS485 communication output
internal power supply--3.6V lithium battery (ER26500)
Overall power consumption:external power<1W
internal power<0.3W, lithium battery can last more than 3 years
Output signal:working condition pulse output,frequency output that proportional to standard volume flow ,4-20mA signal, Quantitative pulse signal (used with IC card),upper and lower limit alarm signal,RS485 communication
IP grade:IP65
