FLOW Range TYPICAL APPLICATIONS • Burner Management • Leak Tests • Gas Consumption • Gas Blending • Shielding Gas • Laser Cutting • Die Casting Features • Mass flow measurement with integrated temperature and pressure correction • Visual readout of flow rate or total, pressure, and temperature • Programmable set points • No moving parts reduces maintenance • Wide turndown for precision measurement at low or high flow • 10-point calibration (NIST Traceable certificate available) General Description Laminar Flow Element differential pressure flowmeters are good for clean, dry, non-corrosive, noncondensing gasses. Corrected for temperature and pressure, it has a mass flow output. The analog (4-20 mA) output along with 2 programmable alarm set points make the meters suitable for process automation systems. NIST traceable and CSA units are Type 4 weatherproof. The accuracy is less than 1% of reading subject to limitations described in the Specifications section. The integrated LCD display can indicate flow rate or total as well as gas temperature and pressure. Calibration is done on air with empirically derived conversion factors. Oxygen cleaning optional. Sizes range from 1/8 to 3/4 inch threaded connections. Anodized aluminum is the standard material for the meter body and 316 Stainless Steel is available for use where external corrosion is

Principles of Operation DIFFERENTIAL PRESSURE TEMPERATURE SENSOR ABSOLUTE PRESSURE DOWNSTREAM PRESSURE INPUT FLOW OUTPUT FLOW Laminar Flow Elements PRINCIPLES OF OPERATION: Flow of gas through a Laminar Flow Element generates a diﬀerential pressure between the absolute and downstream pressure sensors. This diﬀerential pressure is proportional to the ﬂow velocity and viscosity of the gas. Mass ﬂow rate is determined by utilizing the temperature and absolute pressure sensor to compensate for density variations of the gas. General Specifications Flow Ranges High Pressure Drop (2.6 psi)1...
