SLG Liquid Flow Meter Series Ultra-High Pressure Flow Meter for LC Applications ■ Ultra-low Flow Sensing in the nl/min Range ■ Operating Pressure up to 1200 bar (17500 psi) ■ 40 ms Response Time Interface Options Product Summary The SLG Liquid Flow Meter enables precise, bi-directional measurements of dynamic liquid flow rates in the nl/min to low pl/min range. This device has been designed for ultra-high pressure applications in Liquid Chromatography Systems (UHPLC). Excellent bio-compatibility and chemical resistance is ensured by the use of fused silica, stainless steel and PEEK for all wetted parts.

1.1 Precision/Extended Mode with the SLG-0075 The SLG-0075 is offering two different flow sensing modes. The Precision Mode allows for precise flow sensing starting at zero flow while the Extended Mode is made for a rough estimation of the current mass flow in higher flow ranges. The Precision Mode is fully bi-directional with continuous output at and around zero. The Extended Mode is uni-directional (positive flow direction only), and sensor output is restricted to the flow range between 2000 nl/min to 22000 nl/min. The calibration for each mode is stored on a separate calibration field...
