...Venrius has a broad range of purgemeters. The purge rotameters are intended for general use as a low-cost method of flow indication. It is suitable for the majority of non-critical purge applications that do not necessarily require high flow measurement accuracy. Their primary use is to regulate small gas or liquid purge streams. They are used to keep instruments from coming into contact with hot and corrosive fluids, to keep pressure taps from plugging, to keep optical devices clean, and to keep electrical devices from igniting when they come into contact with flammable materials.
