Aalborg P Series Single Tube Flow Meter (150 mm Scale)

Designed for low flow rates, the Model P flowmeter is a precision instrument embodying the inherent simplicity, versatility and economy of the classical rotameter. It is particularly suitable formetering carrier gases in chromatography,indicating and controlling gases in manufacturing processes, liquid and gas measurement in laboratories, pilot plants, flow and level indicating,etc. Shipped completely assembled, flow meters 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 flow tubes selected from the Flow Capacities tables (See Below). Panel mounting style is convertible to bench mounting through the use of the optional acrylic tripod. The tripod option has a built-inspirit leveler and leveling screws.

Meters are available with built-in needle valves (CVTM), high precision metering valves (MFVTM) with "non-rising stems", or with no valves. The higher cost  of MFVTM valves is justified whenever high sensitivity control and resolution are desirable particularly in conjunction with metering tubes of very low flow rates. Generally, for gas metering it is recommended that valves are positioned at inlets (bottom) for liquids valves may be positioned either at inlets or outlets (top). For vacuum services, valves must be mounted at outlets. If unspecified at the time of ordering, meters will be shipped with valves mounted at the inlets.

Features:

• Rib-guided or fluted metering tubes facilitate stable, accurate readings.
• Magnifier lens in front shield to enhance reading resolution.
• Interchangeability of flowtubes and floats.
• Ease of installation and exchange of flowtubes.
• "Non-rotating" adaptor feature - glass flow tubes are prevented from turning during the 
  tightening phase of the assembly procedure.
• OPTIGRAD scales minimize parallax and eye fatigue.
• Chemical compatibility.
• Simple means of panel mounting. Panel mounting is convertible to bench mounting through the
  use of an optional acrylic tripod base with spirit leveler (catalog No. TP1).
