Designed for low to medium flow rates for highly corrosive or ultra-pure liquids and gases. Aalborg T series scale length is 65 mm.
Incorporating the principles of traditional variable area flow technology, these rugged Teflon® PTFE-Glass flowmeters offer solutions to low to medium flow range measurements of highly corrosive or ultra-pure liquids and gases. Wetted inert components are surrounded by structurally rigid anodized aluminium. The resultant design represents a unique combination of a rugged mechanically rigid frame and chemically inert wetted parts. For additional protection of personnel each meter is supplied with a thick protective magnify-ing safety shield.
Shipped completely assembled, flowmeters include standard mounting fittings in a choice of materials, side plates, thick protective magnifying front shield and back plate, optional built-in control valve, and flowtubes selected from the Flow Capacities tables. Panel mounting style is convertible to bench mounting through the use of the optional acrylic tripod. The tripod has a built-in spirit leveler and leveling screws.
BUILT-IN VALVES
Meters are available with built-in needle valves (CVT™ ), high precision metering valves (HRT™) with “non-rising stems”, or with no valves. The higher cost of HRT™ valves is justified whenever high sensitivity control and resolution are desirable particularly in conjunction with metering tubes of very low flowrates.
When meters with valves are ordered the valve cartridges are installed at the inlet. For vacuum service it is
recommended that meters are ordered with valves at the outlet.
