Flow Meter LC M80 Liquid control rotary motion positive displacement (PD) meters offer the ultimate in measurement accuracy for custody transfer of petroleum products, aviation fuels, LPG, and a a board 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.
The LC meter consist 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.
Superior performance features Flow Meter LC M80
- 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 installation requirements.

Performance specifications
Liquid controls positive displacement meters are engineered to provide accurate performance and a long, trouble free service life requiring minimal maintenance with few replacement parts. The unique cast-case construction of the 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 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 meters are UL listed for metering liquid propane gas (LPG).
