±1% Accuracy Linear Output Thermal Technology For Using in Non Corrosive Gas Power Supply Included The NEW-FLOW Thermal Mass Flow Meters provide high performance. Thermal Technology offers advantages in accuracy, sensitivity and turn quality components and the latest technology are combined to provide reliable, compact meters and controllers. The ULFC Series comes without an LCD display, and all models come with linear 0-5VDC and 4-20mA output. The ULFC Series measures the mass flow rate of gases in 18 ranges from 0-10 SCCM to 0-50 SLM as shown in the range table. The ULFC Series combines a mass flow transducer with an electromagnetic proportional valve. Valves are not recommended as shut off valves. Controllers use a 0-5VDC linear set-point signal supplied from the local set-point pot or from a remote souce. Technical Data Wetted Material: Standard flowbody-SS316; option available.
