詳細介紹

縮徑型流量計Prowirl R 內(nèi)置一級或二級縮徑，可以有效的測量小流量。Prowirl R真實的滿足行業(yè)標(biāo)準(zhǔn)的兩線制技術(shù)，無縫集成到現(xiàn)有的基礎(chǔ)設(shè)施和控制系統(tǒng)。由于本質(zhì)安全設(shè)計和熟練的安裝，即使在危險區(qū)域也能有高度的操作安全。

內(nèi)置溫度測量，用于飽和蒸汽質(zhì)量和能量流的測量。
經(jīng)濟、省時：一級縮徑無需改裝管道
高可用性：穩(wěn)定性好，抗震性強，抗溫度沖擊和水錘沖擊
免維護：生命周期標(biāo)定
儀表接線方便，獨立接線腔
操作安全：顯示模塊帶觸摸鍵，背光顯示，無需打開儀表操作
內(nèi)置驗證技術(shù)：心跳技術(shù)

首選測量濕/飽和/過熱蒸汽，可測量氣體和液體（包括低溫液體）。用于低流量或漸小流量的應(yīng)用測量。

設(shè)備參數(shù)

集成直徑減小為1或2行
公稱直徑（交配管）可達DN 250 (10")
根據(jù)行業(yè)標(biāo)準(zhǔn)，定制安裝長度
顯示模塊帶數(shù)據(jù)傳輸功能
堅固耐用的雙腔室外殼

工廠安全：通過多項國際認(rèn)證（SIL，危險區(qū)域）

測量原理	渦街
主要特點	The flowmeter with the same accuracy despite line size reduction, available as compact or remote version. Integrated temperature measurement for mass/energy flow of saturated steam. Dedicated for applications with very low or reduced flow.
特點	Cost and time saving – no pipework modifications needed for line size reduction. High availability – proven robustness, resistance to vibrations, temperature shocks & water hammer. No maintenance – lifetime calibration. Integrated diameter reduction by 1 or 2 line sizes. Nominal diameter (mating pipe) up to DN 250 (10").
Transmitter features	Convenient device wiring – separate connection compartment. Safe operation – no need to open the device due to display with touch control, background lighting. Integrated verification – Heartbeat Technology. Display module with data transfer function. Robust two‐chamber housing.
