Flow Meter Liquid Controls
Flowmeter Avery Hardoll Bulkmeters
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 Avery Hardoll Bulkmeters
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 Avery Hardoll Bulkmeters

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).
