COX Flow Measurement's LoFlo Series turbine flowmeter is a robust axial turbine
flowmeter with repeatability of A plus or minus 0.25 percent of reading. Constructed of 316
stainless steel with -6 AN (MS) end-fittings, the meter employs a proprietary
Si3N4 ceramic ball bearing system, which makes it suited for the demands of
water, hydrocarbon and cryogenic fluid applications. Turbine flowmeters using
ceramic bearings benefit from reduced friction, corrosion resistance, increased
durability and a wide temperature range - contributing to longer life. Ceramic
ball bearings have considerably less friction than journal or sleeve bearings,
which, in turn, extends the usable range of the flowmeter and improves the
repeatability of the flow measurement. Less friction translates into reduced
wear, and thus less calibration drift.
The LoFlo Series meter uses a precision, lightweight 17-4 helical rotor and is
calibrated on primary standard equipment. The helical blade profile transfers
energy, reducing bearing wear, pressure drop and their associated cost. The
compact LoFlo Series flowmeter (2.21 inch face dimension) is not
position-sensitive and can be mounted in any piping orientation. It is designed
to measure flows as low as 0.006 GPM (0.024 LPM). Typical uses include fuel
injection production systems, blending of costly chemical additives, onboard
fuel consumption, refrigerants and dye injections.
