The MTHF Series comes with or without an LCD display, and all models come with linear 0-5 V DC and 4-20 mA output. The MTHF Series measures the mass flow rate of gases in 18 ranges from 0-10 NLPM to 0-50 NLPM as range table. The MTHF Series combine a mass flow transducers with an electromagnetic proportional valve. Valves are not recommended as shut of valves. Controllers us a 0-5 V DC liner set-point signal supplied from the local set-point point or from a remote source.
