進(jìn)口氣體腰輪流量計(jì) 品牌：美國(guó)威盾VTON 產(chǎn)品描述Product description 進(jìn)口氣體腰輪流量計(jì)它由傳感器和轉(zhuǎn)換顯示儀組成，傳感器采用多葉片的轉(zhuǎn)子感受流體的平均流速，從而推導(dǎo)出流量或總量。渦輪流量計(jì)是一種速度式儀表，它具有精度高，重復(fù)性好，結(jié)構(gòu)簡(jiǎn)單，運(yùn)動(dòng)部件少，耐高壓，測(cè)量范圍寬，體積小，重量輕，壓力損失小，維修方便等優(yōu)點(diǎn)，用于封閉管道中測(cè)量低粘度氣體的體積流量和總量。每臺(tái)表的葉片都經(jīng)過(guò)動(dòng)平衡嚴(yán)苛檢測(cè)，通過(guò)音速噴嘴標(biāo)定臺(tái)逐臺(tái)多點(diǎn)標(biāo)定后才能夠準(zhǔn)許出廠。它先將流速轉(zhuǎn)換為渦輪的轉(zhuǎn)速，再將轉(zhuǎn)速轉(zhuǎn)換成與流量成正比的電信號(hào)。其輸出信號(hào)為頻率，易于數(shù)字化。產(chǎn)品主要有基本型和溫壓補(bǔ)償型兩種形式，基本型測(cè)量單一流量信號(hào)，溫壓補(bǔ)償型可統(tǒng)一實(shí)現(xiàn)測(cè)量溫度、壓力、標(biāo)方流量的測(cè)量。每種形式都有整體、分體結(jié)構(gòu)，以適用不同的安裝環(huán)境。已廣泛應(yīng)用于石油、化工、科研、輕紡、鍋爐等領(lǐng)域。 The gas waist wheel flow meter consists of a sensor and a conversion display. The sensor uses a multi-blade rotor to sense the average flow rate of the fluid, thereby deriving the flow rate or total volume. Turbine flowmeter is a speed meter. It has the advantages of high accuracy, good repeatability, simple structure, few moving parts, high pressure resistance, wide measurement range, small size, light weight, small pressure loss, and easy maintenance. It is used for Measurement of volume flow and total quantity of low viscosity gases in closed pipes. The blades of each meter have been rigorously tested by dynamic balance, and can be allowed to leave the factory only after passing multi-point calibration on a sonic nozzle calibration table. It first converts the flow rate into the rotation speed of the turbine, and then converts the rotation speed into an electrical signal proportional to the flow rate. Its output signal is frequency and is easy to digitize. The product mainly comes in two forms: basic type and temperature-pressure compensation type. The basic type measures a single flow signal, while the temperature-pressure compensation type can uniformly measure temperature, pressure, and standard flow. Each form has an integral or split structure to suit different installation environments. It has been widely used in petroleum, chemical industry, scientific research, textile, boiler and other fields. 進(jìn)口氣體腰輪流量計(jì)應(yīng)用行業(yè)Application industry ●天然氣 ●城市煤氣、LPG ●丙烷、丁烷 ●空氣、氮?dú)?/p> ●工業(yè)惰性氣體 進(jìn)口氣體腰輪流量計(jì)特點(diǎn)Characteristic ● 采用進(jìn)口儀表專用精密軸承，穩(wěn)定性、潤(rùn)滑性好。 ● 精心設(shè)計(jì)的流道結(jié)構(gòu)，提高了流量計(jì)的介質(zhì)適應(yīng)性。 ● 獨(dú)特的反推結(jié)構(gòu)和密封結(jié)構(gòu)設(shè)計(jì)，確保軸承長(zhǎng)期可靠運(yùn)行。 ● 流量計(jì)表頭可以旋轉(zhuǎn)180°，安裝使用簡(jiǎn)單方便。 ● 優(yōu)良的整流器整流性能，前后直管段要求很低。 技術(shù)參數(shù) 項(xiàng)目 | 參數(shù) | 產(chǎn)品名稱 | 進(jìn)口氣體腰輪流量計(jì) | 品牌 | 美國(guó)威盾VTON | 儀表口徑 | DN20 ~ DN300 | 精度等級(jí) | ±1.5%、±1.0%（需特制） | 直管段要求 | 前≥2DN，后≥1DN | 儀表材質(zhì) | 表體：304不銹鋼 葉輪：優(yōu)質(zhì)鋁合金 轉(zhuǎn)換器：鑄鋁 | 使用條件 | 介質(zhì)溫度：-20℃~+80℃ 環(huán)境溫度：-30℃~+65℃ 相對(duì)濕度： 5% ~ 90% 大氣壓力： 86kpa ~ 106kpa | 工作電源 | 外電源：+24VDC±15%，適用于4~20mA輸出、脈沖輸出、RS485 內(nèi)電源：1組3.6V10AH鋰電池，當(dāng)電壓低于2.0時(shí)出現(xiàn)欠壓指示 | 儀表顯示 | 液晶顯示，瞬時(shí)流量，累計(jì)流量，帶溫壓補(bǔ)償?shù)目娠@示溫度和壓力 | 信號(hào)輸出 | 脈沖信號(hào)、4~20mA、IC控制信號(hào) | 通訊輸出 | RS485通訊 | 信號(hào)線接口 | 內(nèi)螺紋M20×1.5 | 防爆等級(jí) | ExdIICT6 | 防護(hù)等級(jí) | IP65 |
