 In Line Flow Meters
V meters are designed with uniquerotatable scales of dual air-water direct reading graduationsshowing SCFM and L/min (air), as well as GPMand LPM (water) markings.
 
Heavy-duty flow meters are fully enclosed in a brushed stainlesssteel case. Ideal for industrial applications with flow rates of up to116 GPM / 440 L/min and 250 SCFM /7080 L/min. Used for flowmeasurements of liquids (water) and gases (air).
 
Made entirely of PTFE, PFA, and PCTFE, theModel F flow meter is excellent for high-purityapplications or use with corrosive liquids.

 GFM mass flow meter
A low cost solution to thermal mass flow metering for gases is presented by Aalborg in introducing the model GFM mass flow meter line.
The GFM design combines the convenience and accuracy of conventional mass flow devices with low costs previously unattainable.

 KITS
Designed especially for the laboratory these kits offer a diverse economical way of acquiring flow measurement capabilities. Since all 150 mm flow tubes in this catalog are interchangeable, additional flow tubes may be added later (see flow tables, pages 43 to 49). A handy selection of flow meters is presented in kit form.
 
THREE TYPES OF KITS ARE OFFERED
✓ Aluminum Flow Meter Kit.
✓ Stainless Steel Flow Meter Kit.
✓ PTFE Flow Meter Kit.
 
For non-corrosive fluids use the Aluminum Kit.  For corrosives consider the Stainless Steel Kit.  For corrosive applications at lower pressure orfor high purity fluid service specify the PTFE Kit.

 Model G GAS PROPORTIONERS BACK PRESSURE COMPENSATED
To blend two or three gases in homogeneous infinitely variable concentrations, directly at the end use point, this Model G gas proportioner is unsurpassed in convenience and economy.  Gas proportioners pay for themselves since they eliminate the need for expensive custom blended gas mixtures.
 
design features
✓ Blending of two or three gases withgas proportioners obviates the need for:
✓ ORDERING FIXED GAS MIXTURES.
✓ CONTAMINATION FROM REUSABLE GAS CYLINDERS.
✓ POTENTIALLY INACCURATE MIXTURES BY GAS SUPPLIERS.
✓ Rib-guided or fluted metering tubesfacilitate stable, accurate readings.
✓ OPTIGRADTM scales minimize parallaxand eye fatigue.
✓ Interchangeability of flow tubesand floats.
✓ Simple means of panel mounting.

 PX MULTIPLE TUBE FLOW METERS
Px meters are convenient for applications where several streams of gases or liquids are to be metered in individual channels, or manifolded.
 
design features
✓ Rib-guided or fluted metering tubes facilitate stable, accurate readings.
✓ Interchangeability of flow tubes and floats.
✓ Manifolding at inlet or outlet.
✓ Ease of installation and exchange of flow tubes.
✓ "Non-rotating" adapter feature -glass flow tubes are preventedfrom turning during the tighteningphase of the assembly procedure.
✓ OPTIGRADTM scales minimizeparallax and eye fatigue.
✓ Chemical compatibility.
✓ Simple means of panel mounting.
 
Meters may be supplied with built-in needle valves (CVTM), high precision metering valves (MFVTM) with "non-rising stems", or with no valves. Generally for gas metering, it is recommended that valves are positioned at inlets (bottom) for liquids valves may be positioned either at outlets (top) or inlets.

 MULTIPLE TUBE-PTFE GLASS FLOW METERS Tx
They are ideal for applications where several streams of corrosive gases or liquids are to be metered in individual channels or as a controlled mixer in manifolded models.
 
design features
✓ Constructed of inert materials:Borosilicate Glass, PTFE and PCTFE.
✓ Chemical inert wetted partswithin mechanically rigid frame.
✓ Rib-guided or fluted metering tubesfacilitate: stable, accurate readings.
✓ OPTIGRADTM scales minimizeparallax and eye fatigue.
✓ Simple means of panel mounting.
✓ Interchangeability of flow tubesand floats.
✓ Conveniently overlapping flowranges available in both standardmillimeter and direct reading scales.
 
For vacuum service it is recommended that meters are ordered with valves at the outlet.

 SINGLE TUBE FLOW METERS
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 for metering carrier gases in chromatography, indicating and controlling gases in manufacturing processes, liquid and gas measurement in laboratories, pilot plants, flow and level indicating,etc.
 
design features
✓ Rib-guided or fluted metering tubesfacilitate stable, accurate readings.
✓ Magnifier lens in front shield to enhanceread ing resolution.
✓ Interchangeability of flow tubes and floats.
✓ Ease of installation and exchange offlow tubes.
✓ "Non-rotating" adapter feature - glassflow tubes are prevented from turningduring the tightening phase of theassembly procedure.
✓ OPTIGRADTM scales minimize parallaxand eye fatigue.
✓ Chemical compatibility.
✓ Simple means of panel mounting.
 
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.
