Cole-Parmer MC-250SLPM-D/5M 流量控制器

多功能，高精度差壓式質(zhì)量流量計

精確讀數(shù)到0.8%，滿量程0.2%，可重復(fù)性0.2

用戶可根據(jù)顯示器選擇測量標(biāo)準(zhǔn)氣體，氣體種類達(dá)30種

100 - 1調(diào)節(jié)范圍1 SCCM全刻度達(dá)1000 SLPM

型號可供4至20 mA輸出或累加器

這些流量計通過壓降層流元件（LFE）測量流量。由于水流元素使得流層，安置在這個過程中不需要流量計直管段上游或下游運行，極大地簡化了安裝。

相比熱式質(zhì)量技術(shù)，LFE的設(shè)計響應(yīng)超快，10毫秒內(nèi)，并提供即時使用，無需熱身時間。

顯示器周圍的集成鍵盤，是所有編程服務(wù)所需的元件。0至5 VDC輸出允許傳輸流量值到遠(yuǎn)程顯示器，錄像機(jī)或調(diào)節(jié)閥或泵的控制器。

對于便攜式流量計量的應(yīng)用程序，訂購電池列在附件。

包括： 120/230 VAC電源適配器與通信電線32929-89和由制造商提供NIST可溯源校準(zhǔn)報告。

Versatility and high accuracy from a laminar-based mass flowmeter

Accuracy of ±0.8% of reading ±0.2% full-scale; repeatability of ±0.2%

Measure 30 standard gases—user selectable from display

100 to 1 turndown with ranges of 1 SCCM full-scale up to 1000 SLPM

Models with 4 to 20 mA output or totalizer are available

These meters measure flow via pressure drop across a laminar flow element (LFE). Because the flow element makes the flow stream laminar, placement in the process does not require straight pipe runs upstream or downstream of the meter, greatly simplifying installation. As compared to thermal mass technologies, the LFE design provides an ultrafast response within 10 milliseconds and offers “instant on” with no warm-up time.

An integrated keypad around the display is all that is required to program the unit for service. The 0 to 5 VDC output allows transmission of the flow value to a remote display, recorder, or controller regulating a valve or pump.

For portable flow metering applications, order the battery pack listed under accessories.

What's Included:

120/230 VAC power adapter with communications cable 32929-89 and NIST-traceable calibration report supplied by the manufacturer.
