Product Description
Functions and Characteristics
■
Patent rectification technology can maintain the measurement
reliability under unfavorable installation condition and relatively
significant change of medium speed flow condition.
■
Patent dust-proof structure can effectively prevent impurities in
the medium from entering into bearing and resulting in rapid
wearing and deadlock.
■
Minimum installation requirement, in which the front straight pipe
section ≥ 2D can ensure measurement accuracy of the
flowmeter.
■
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.
■
Aluminum alloy turbine is characterized in high strength, corrosion
resistant, ageing resistant, long service life, high accuracy and
well repeatability.
■
Advanced microcomputer technology and mono-chip computers with high
performance enable the complete machine to have more powerful
function and more excellent performance.
■
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.
■
Large screen back-lighting LCD display can be read clearly and
visually in darker environment.
■
Infrared remote operator may be matched
andparameter setting can be carried out withoutopening the front
cover of flowmeter.
■
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.
■
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.
■
Adopt data save technology E*-PROM which can save the parameter
setting for a long time after power failure.
■
Low voltage alarm of internal battery (≤2.7V) can remain the user
to replace the battery in time.
■
The intelligent flow totalizer can be turned **0° for convenient
reading.
■
Data can be saved automatically when there is power failure to
prevent data loss.
■
Signal output check function is provided. It can output the
standard current signals of 4, 8, *2, *6 and *0
mA.
■
Liquid crystal display screen of totalizer can withstand high
temperature of *0℃.
■
External power supply is isolated from the main circuit of
flowmeter with isolated voltage up to 1,**0 V.
■
Reliable electromagnetic compatibility design.
