Description of DN50 4-20mA Water Flow Meter RS485 HART High Accuracy Advanced
Technical
LWGY series turbine flow meter adopt advanced technical of abroad
flow instrument, characteristic of simple structure, high accuracy,
good repeatability, convenient installation/maintenance etc. This
flow meter is mainly used to measure liquid flowrate of closed
pipeline, the liquid must without no fiber, particles and other
impurities, can not corrosive with 1Cr18Ni9Ti, 2Cr13, corundum
Al2O3, and cemented carbide, the kinematic viscosity less than
5×10-6m²/s under the working temperature.
Features of DN50 4-20mA Water Flow Meter RS485 HART High Accuracy Advanced
Technical
Good accuracy, usually can reach to ±1%R,±0.5%R, high accuracy can
reach to ±0.2%R;
Good repeatability, short-term repeatability can reach to
0.05%~0.2%;
Output pulse frequency signal, it is suitable for metering and
connected to the computer, no zero drift, strong anti-jamming
capability;
Can get very high frequency signal(3~4kHz),Strong signal
definition;
Large rangeability, large and middle size can reach to 1:20,small
size is 1:10;
Simple structure,convenient installation/maintenance, flow
capacity;
For high pressure measurement, idon't have to open hole on
instrument, easy to made into high pressure type instrument.
