Cole-Parmer L-1LPM-D/5V 差壓式流量計

Cole-Parmer L-1LPM-D/5V 差壓式流量計

實現精確，超快體積測量和控制

技術允許安裝沒有典型的入口/出口直餾需求

設備對多個流體參數：流量，壓力和溫度提供的數據

用戶可通過集成鍵板編程所以程序

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。LFE也提供了一個出色的量程比50:1計測量范圍非常廣泛和準確。該設計提供了超快的響應變化通常在100毫秒內啟動或輸入。0至5 VDC輸出允許傳輸流量值到遠程顯示器，記錄儀，或調節閥或泵控制器。

流量控制器，一個集成的PID控制器所指示的元件的響應過程變化。P和D參數設置定制單位的響應。流量設定點與可選的設定點控制模塊共同建立，一個0到5 V信號，或RS-232輸入信號。

便攜式流量計（不控制）應用程序，訂購電池列在下面。元件可通過儀器上的螺紋抽頭安裝。

流量計和控制器具有動態顯示功能，同時顯示流量，壓力，流體溫度，和（控制器）的設定點。元件顯示，電源和輸入/輸出信號通過一個單一的多針連接器傳輸，

包括：集成傳感器，顯示器，和變送器，控制器添加閥組件。所有型號都包括一個120/230 VAC電源適配器用通信電纜，由制造商提供的NIST可溯源校準報告。 

Achieve accurate, ultrafast volumetric measurement and control

Technology allows for installation without typical inlet/outlet straight-run requirements

Units provide data on multiple fluid parameters: flow, pressure and temperature

All functions are user-programmable through an integrated keypad

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. The LFEs also provide an outstanding turndown ratio of 50:1 giving the meter a very broad and accurate measuring range. The design provides an ultrafast response at start-up or input change—often within 100 milliseconds. 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 the flow controllers, an integrated PID controller directs the unit’s response to process changes. Set the P and D parameters to tailor the unit’s response. Flow setpoint is established with the optional set point control module, a 0 to 5 V signal, or an RS-232 input signal.

For portableflow metering (not controlling) applications, order the battery pack listed below. Units can be mounted via threaded taps in the meter body.

Meters and controllers feature dynamic display that simultaneously shows flow rate, line pressure, fluid temperature, and (for controllers) the set point. For the units shown, both power and input/output signals are transmitted through a single multi-pin connector.
