Product Introduction


HWQZ series gas Intelligence turbine flow meter is new precision measurement meter with

high-accuracy, high-reliability.

HWQZ series gas intelligence turbine flow meter satisfy  International standard IS09951.


Principles

 

When flow into flux meter, under the baffle {or rectifier)'s action, it is adjusted and accelerated, because

between turbine lamina and liquid has one angular, at this time turbine generate driving moment, after

conquer friction moment and fluid resistance moment, turbine start to rotate. Under stated flux range,

turbine rotated angular velocity and fluid volume flux being direct ratio. Follow law of electromagnetic

induction, use magneto-dependent sensor to induce the impulse signal, this signal and pressure,

temperature signal operation disposal, which through magnify, filtering, shaping, and then send into

the intelligent volume modify equipment, and display on the LED screen,

 

Characteristics

 

High precision, good repeatability, wide range ratio, could get 1:20{or more};

 

Use well-design inversed construction and particular pressurize construction, insure bearing long-term

running reliability; Integrated two-stage rectifier, much low fore and after straight tube requirement (fore~20N ,afte~1 ON) i

 

Intelligent volume amendment instrument can turn about 3400, be the same with any installations; Use maintenance-free bearing and stainless steel oil filling bearing;

 

Meter has real time data-base, could compose telephone net, convenient to concentrate data and real time management;

 

Gather high-precision temperature, pressure, flux sensor and intelligent volume amendment instrument to

one body, implement gage to object;


Use low power consumption high technology, inner and outer electricity source supply power, whole

machine power consumption is low, directed display flux value and measure parameters, and has many

transition function;

 

It has realtime data store function, could prevent data lost while change battery or stop by accident,

under the power off state, Interior parameter could reserve forever;


Meter has explosion protection function, explosion protection symbol is Exib1lBT4;

 

The technique index meet the requirement IS09951, whole machine appearance beautiful, performance

reliable, reach international advanced level

Nominal diameter:DN25(1")-DN200(8");

 

Flux range: 2.5-2500 m³/h

 

Pressure grade:1.6、2.5、4.0MPa;

 

Shell material:aluminum alloy or stainless steel;

 

Inner electrical source:3.6VDC Li-battery, screen real time display the battery capacity percent

(tendency value)for promoting consumer to change battery;

 

Outer electrical source:6-24VDC, ripples50mV, when meet outer electrical source,inner electrical

source would cut-off by itself, whole machine will be supplied power by outer electrical source;

 

Impulse signal (three-wire system) :match with instantaneous delivery;

 

(4-20) mA standard analog signal:connection mode two-wire system or three-wire system, power supply

mode is +24VDC outer electrical source;

 

Standard flux signal:through impulse signal mode output, each impulse delegates 0.1 m3~ 1 m3 capacity. Be the same with IC card to support using;

 

RS-485 interface signal:directly networking with up grade computer, it can transfer the temperature,

pressure, instantaneous flux of measured medium, standard volume gross, meter related parameters,

accident code, running state and real time data. With special MODEM support using, it can implement

telephone communication, one special MODEM could match 8 flux meters
