進口氣體腰輪流量計 品牌：美國威盾VTON 產(chǎn)品描述Product description 進口氣體腰輪流量計它由傳感器和轉換顯示儀組成，傳感器采用多葉片的轉子感受流體的平均流速，從而推導出流量或總量。渦輪流量計是一種速度式儀表，它具有精度高，重復性好，結構簡單，運動部件少，耐高壓，測量范圍寬，體積小，重量輕，壓力損失小，維修方便等優(yōu)點，用于封閉管道中測量低粘度氣體的體積流量和總量。每臺表的葉片都經(jīng)過動平衡嚴苛檢測，通過音速噴嘴標定臺逐臺多點標定后才能夠準許出廠。它先將流速轉換為渦輪的轉速，再將轉速轉換成與流量成正比的電信號。其輸出信號為頻率，易于數(shù)字化。產(chǎn)品主要有基本型和溫壓補償型兩種形式，基本型測量單一流量信號，溫壓補償型可統(tǒng)一實現(xiàn)測量溫度、壓力、標方流量的測量。每種形式都有整體、分體結構，以適用不同的安裝環(huán)境。已廣泛應用于石油、化工、科研、輕紡、鍋爐等領域。 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. 進口氣體腰輪流量計應用行業(yè)Application industry ●天然氣 ●城市煤氣、LPG ●丙烷、丁烷 ●空氣、氮氣 ●工業(yè)惰性氣體 進口氣體腰輪流量計特點Characteristic ● 采用進口儀表專用精密軸承，穩(wěn)定性、潤滑性好。 ● 精心設計的流道結構，提高了流量計的介質適應性。 ● 獨特的反推結構和密封結構設計，確保軸承長期可靠運行。 ● 流量計表頭可以旋轉180°，安裝使用簡單方便。 ● 優(yōu)良的整流器整流性能，前后直管段要求很低。 技術參數(shù) 項目 | 參數(shù) | 產(chǎn)品名稱 | 進口氣體腰輪流量計 | 品牌 | 美國威盾VTON | 儀表口徑 | DN20 ~ DN300 | 精度等級 | ±1.5%、±1.0%（需特制） | 直管段要求 | 前≥2DN，后≥1DN | 儀表材質 | 表體：304不銹鋼 葉輪：優(yōu)質鋁合金 轉換器：鑄鋁 | 使用條件 | 介質溫度：-20℃~+80℃ 環(huán)境溫度：-30℃~+65℃ 相對濕度： 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 內電源：1組3.6V10AH鋰電池，當電壓低于2.0時出現(xiàn)欠壓指示 | 儀表顯示 | 液晶顯示，瞬時流量，累計流量，帶溫壓補償?shù)目娠@示溫度和壓力 | 信號輸出 | 脈沖信號、4~20mA、IC控制信號 | 通訊輸出 | RS485通訊 | 信號線接口 | 內螺紋M20×1.5 | 防爆等級 | ExdIICT6 | 防護等級 | IP65 |
