Five stars manufactures metal tube rotameters are available for use in harsher duties in liquids and gases, where glass tubes are not allowed for safety reasons. These are very rugged and robust, yet inexpensive for flow rate indication purposes. It can be used for opaque and turbid fluids at high operating temperature and pressure. The flow is indicated by a pointer, which is magnetically coupled with the float that rises in a tapered tube with increase in flow. Features: ss/teflon lined body; die-cast aluminium housing with aluminium pointer and ss 304 hardware; high pressure and temperature service; line size from 1/2" to 4"; flow range 100 to 60000 lph for water and 2000 m3/hr for air; and flanged connection to any standard as a, bst, din, etc.
