Flow Meter LC M25 Liquid controls rotary motion positive displacement (PD) meters offer the ultimate in measurement accuracy for custody transfer of petroleum products, aviation fuels, LPG, and 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 hosing 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 M25
- Low pressure drop—will operate on gravity flow or pump pressure
- Sustained accuracy—no wear from metal-to-metal contact inside the measuring chambers 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 Specification
Liquid control positive displacement meter 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 flows meters’ compact design and multiple inlet/outlet flange configurations provide unmatched mounting versatility.
LC meter meet NTEP (NIST Handbook 44) and International Weight and measures accuracy requirements as well as U.S. Military specification meter are UL listed for metering propane gas ( LPG)

Temperature Range
40º F to 160º F (-40º C to 71º C)
- Stated accuracy obtainable when all variables remain constant. Reading/ measurements reflect a minimum of one minute of flow at selected rate(s). All accuracy statements based on metering safety solvent (aliphatic hydrocarbon), approximate viscosity 1 CPS. On higher viscosity products, the average deviation in accuracy will be less.
