Gas Turbine Flowmeter

 XK-LWQ type gas turbine flow sensor is a flow meter at home and abroad to learn advanced technology and optimized design, a combination of gas mechanics, fluid mechanics, electromagnetic theory and self-developed a new generation of high-precision, high reliability gas precision measurement instruments, with excellent low and high pressure measurement of performance, a variety of signal output and low sensitivity measurement of flow disturbances, widely used in natural gas, coal gas, liquefied petroleum gas, light hydrocarbon gas and other gases. Kind of turbine flow product itself does not have on-site display, only traffic signal in a manner remote pulse signal output. Instrument inexpensive, high integration, small size, especially for the secondary display device, PLC, DCS and other control systems with the use of a computer. Kind of turbine flowmeters are explosion-proof products, explosion-proof grade: ExdIIBT6. Second, product characteristics * High-quality alloy turbine has higher steady flow and resistance to the corrosive effects · imported high quality bearings life ? metering chamber and the breather chamber cut off to ensure the safety of a wide range · flow meter (Qmax / Qmin ≥20: 1), repeatability, high accuracy (up to 1.0), a small pressure loss, low starting flow rate, up to 0.6m3 / h · Instruments with explosion-proof and protection, Ex logo ExdⅡBT6, ExiaⅡCT6, protection IP65 and three meter classification 1. Press the instrument functional classification XK-LWQ series gas turbine flowmeter can be divided into three categories, namely:??? Gas turbine flow sensor / transmitter intelligent integration gas turbine flowmeter intelligent temperature and pressure compensation integrated gas turbine flowmeter 2 . Function Description ■ gas turbine flow sensor / transmitter such turbine flow product itself does not have on-site display, only traffic signal remote output. Traffic signals can be divided into a pulse signal or current signal (4-20mA); low meter price, high integration, small size, especially for the secondary display device, PLC, DCS and other control systems with the use of a computer. Kind of turbine flowmeters are explosion-proof products, explosion-proof grade: ExdIIBT6. According to different output signals, such products can be divided into XK-LWQ-N- type and XK-LWQ-A- type XK-LWQ-N- type XK-LWQ-A- type display no site showed no on-site display signal output three-wire pulse output, high ≥8V, low ≤0.8V conditions 4-20mA or 24VDC 24VDC power supply 12 proof rating ExdIIBT6 ExdIIBT6 applications: as a condition traffic signal acquisition instruments, traffic signal away transmitted to the host computer ■ intelligent integration gas turbine flowmeter integrated intelligent instrument, using double LCD live display, with a compact body, intuitive readings clear, high reliability, without external power interference, anti-lightning, obvious low cost advantage . Class turbine flowmeter in accordance with power supply, the availability of remote signal output can be divided into XK-LWQ-B- type and XK-LWQ-C type. XK-LWQ-B- type XK-LWQ-C- type display also shows the instantaneous flow rate operating condition, the total cumulative flow also shows the instantaneous flow rate operating condition, the total cumulative flow signal output without conditions 4-20mA, workers Condition pulse power supply 3V lithium battery (more than 4 years in a row applicable) 24VDC external power supply proof rating ExdIIBT6 ExdIIBT6 applications: 1. temperature, pressure relatively stable site conditions, as industrial control instruments 2. In temperature, pressure relatively stable The site conditions, the user can scale operation to traffic conditions based on instrument represents the value of the gas equation. ■ intelligent temperature and pressure compensation integrated gas turbine flowmeter XK-LWQ-D type gas turbine meter built-in temperature, pressure sensor and intelligent flow totalizer, through micro-processing unit for real-time acquisition of flow, temperature, pressure signal in accordance with the gas equation temperature pressure compensation, automatic compression factor correction, then the volume flow under standard conditions intuitive displayed. ※ standard state flow (flow standard conditions): Under 20 ℃, atmospheric pressure gas flow of life also shows the instantaneous flow display mode under standard conditions, the daily cumulative flow, total cumulative flow rate and temperature, pressure, battery power and other data signal output standard conditions 4-20mA, pulse signal conditions, standard conditions pulse signal, IC card signal, RS485 communication protocol 24VDC power supply with dual power supply built-in lithium battery and external supply, when users do not need any signal output when the instrument can not 24VDC external power supply, the instrument automatically switches to the built-in lithium battery, a battery can work for more than three years. Explosion levels ExdIIBT6 applications: accurate measurement or trade settlement
