Functions and Characteristics
â–     Â
Patent rectification technology can maintain the measurement
reliability under unfavorable installation condition and relatively
significant change of medium speed flow condition.
â–     Â
Patent dust-proof structure can effectively prevent impurities in
the medium from entering into bearing and resulting in rapid
wearing and deadlock.
â–     Â
Minimum installation requirement, in which the front straight pipe
section ≥ 2D can ensure measurement accuracy of the
flowmeter.
â–     Â
Intelligent integrated design can give a dynamic detect for
temperature and pressure of the medium, implement automatic
compensation and compressibility factor correction, and directly
display the standard instantaneous volumetric flow and total
standard volume of gas.
â–     Â
Aluminum alloy turbine is characterized in high strength, corrosion
resistant, ageing resistant, long service life, high accuracy and
well repeatability.
â–     Â
Advanced microcomputer technology and mono-chip computers with high
performance enable the complete machine to have more powerful
function and more excellent performance.
â–     Â
Advanced Hi-tech double power supply and micro power consumption
enables the complete machine of low power consumption and to be
either supplied with internal batteries and run for a long time
(two lithium batteries can be used for 3 years) or connected to
external power to run.
â–     Â
Large screen back-lighting LCD display can be read clearly and
visually in darker environment.
â–     Â
Infrared remote operator may be matched
andparameter setting can be carried out withoutopening the front
cover of flowmeter.
â–     Â
The flowmeter is provided with pulse signal output and may also
output many signals according to user’s need such as 4 - *0 mA
standard analog signals and quantization pulse signals of IC card
etc.
â–     Â
Adopt RS**5, RS**2C, MODBUS, HART protocols: they can be matched
with specific MODEM and constructautomatic meter reading
management system through telephone network, leading to a high
automation level.
â–     Â
Adopt data save technology E*-PROM which can save the parameter
setting for a long time after power failure.
â–     Â
Low voltage alarm of internal battery (≤2.7V) can remain the user
to replace the battery in time.
â–     Â
The intelligent flow totalizer can be turned **0° for convenient
reading.
â–     Â
Data can be saved automatically when there is power failure to
prevent data loss.
â–     Â
Signal output check function is provided. It can output the
standard current signals of 4, 8, *2, *6 and *0
mA.
â–     Â
Liquid crystal display screen of totalizer can withstand high
temperature of *0℃.
â–     Â
External power supply is isolated from the main circuit of
flowmeter with isolated voltage up to 1,**0 V.
â–    Â
Reliable electromagnetic compatibility design.
