In this setup, fluid is forced into laminar (non-turbulent) flow, making the pressure drop directly proportional to volumetric flow. Because the instrument simultaneously measures temperature and absolute pressure, it can calculate actual mass flow rather than just volumetric readings. This approach yields highly precise and repeatable measurements, as the controlled laminar flow path and multi-sensor feedback maintain accuracy even under changing conditions.<\/p>\n<h3><\/h3>\n<h4><span style=\"text-decoration: underline;\">How It Works<\/span><\/h4>\n<ol>\n<li><strong>Flow Conversion<\/strong> \u2013 The device contains an arrangement of thin metal plates that convert incoming turbulent flow into laminar flow.<\/li>\n<li><strong>Pressure and Temperature Measurement<\/strong> \u2013 Sensors measure differential pressure, absolute pressure, and temperature within the laminar flow regime as the fluid passes across the plates.<\/li>\n<li><strong>Flow Calculation<\/strong> \u2013 The pressure and temperature measurements are used in conjunction with the Poiseuille equation to calculate the flow rate.<\/li>\n<\/ol>\n<p><strong><a href=\"https:\/\/www.alicat.com\/support\/theory-of-operation-laminar-differential-pressure-flow-measurement\/\">Read more about the Laminar DP Operating Principle \u2192<\/a><\/strong><\/p>\n<p><strong><\/strong><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=&#8221;1_2,1_2&#8243;
