Harga Flow Meter LC M7 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.
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.
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 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 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.

Relationship of meter pressure drop to flow rate and viscosity
With Liquid Controls’ unique design, the bearing surfaces of the meter element are internally and externally subjected to the same system pressure. Due to the low pressure drop inherent to the LC meter, it is often possible to satisfactorily meter higher viscosity products through a smaller LC meter than its competitive equivalent. Pressure drop through a meter depends on product temperature, viscosity and flow rate. When metering a liquid, the pressure drop will increase as viscosity increases. Illustrated below is the pressure loss vs. flow rate curve for an M-60 meter at 600 GPM on safety solvent. (For additional pressure loss data, consult factory.)
