Designed for direct read flow rates, the FLD Series variable area flow meter is a precision instrument embodying the
inherent simplicity, versatility and economy of the classical variable area flow meter. 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. Shipped
completely assembled, flow meters include standard mounting fittings in a choice of materials, side
plates, thick protective magnifying front shield and back plate, built-in control valve, and flow tubes.
Panel-mounting style is convertible to bench mounting through the use of the optional acrylic tripod,
FLTR-1. The tripod has a built-in spirit leveler and leveling screws.
Meters come with built-in 6 turn needle valves, high precision metering valves with “non-rising stems”
16 turn, or with no valves. The higher cost of the high resolution 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.

Minimum flow rate is 10% of the maximum rate shown.
“G” suffix denotes glass float, “ST” suffix denotes 316 SS float, “C” suffix denotes carboloy float and “S” denotes red sapphire float.
For units without valve, add suffix "-NV" to model number and subtract $10 for aluminum; subtract $13 for for 316SS.
For 16 turn, high resolution non-rising stem valve for 150 mm variable area flow meters, add suffix "-HRV" to model number and add $60 for aluminum units and $120 for stainless steel units.
For O2 Cleaning add "-O2CLEAN" to the part number and $125 to the price.
No NIST traceable calibration is available.
