Flow Meter Liquid Controls
Flowmeter LC MA Series
Liquid Controls M and MA Series rotary motion positive displacement (PD) meters offer
the ultimate in measurement accuracy for custody transfer of petroleum products,
aviation fuels, LPG, and a broad range of industrial liquids. LC meters incorporate a
unique design, presenting minimal intrusion in a flowing stream of liquid, as well as
minimal pressure drop through the meter. Flowmeter LC MA Series
The LC meter consists of a housing in which three synchronized rotors turn with no
metal-to-metal contact. Hydraulic sealing is accomplished by a stationary boundary
layer of liquid, not by the wiping action of mechanical parts. Flowmeter LC MA Series
Superior performance features
Low pressure drop—will operate
on gravity flow or pump pressure.
Sustained accuracy—no wear from
metal-to-metal contact inside the
measuring chamber means minimal
deterioration in accuracy over time,
fewer recalibrations, and longer
service life. Meters conform to NIST
and International Weights and
Measures accuracy requirements.
• Wide temperature range—products
can be metered accurately from -40° F
(-40° C) to 160° F (71° C).
• Wide viscosity range—LC meters can
accurately meter products from less
than 30 SSU (less than 1 centipoise) to
1,500,000 SSU (325,000 centipoise).
• Maximum adaptability—right angle
design with choice of stock or custom
elbows/ fittings provides unequaled
mounting flexibility to meet your
Performance Specifications Flow Meter Liquid Controls
Liquid Controls positive displacement meters are engineered to provide accurate performance and a long, troublefree
service life requiring minimal maintenance with few replacement parts. The unique cast-case construction of
the M and MA Series meters results in low pressure drop for most liquids, delivering superior performance and
minimal demand on system pumps. The exclusive LC metering element eliminates inaccuracies due to clearance
changes, minimizes loads on bearings, eliminates axial thrust and performs with equal accuracy for forward or
reverse flow. M and MA Series meters’ compact design and multiple inlet/ outlet flange configurations provide
unmatched mounting versatility.
LC meters meet NTEP (NIST Handbook 44) and International Weights and Measures accuracy requirements as well
as U.S. Military specifications. MA Series meters are UL listed for metering liquid propane gas (LPG).
