Description Product :
Liquid Control M and MA Series rotary motion positive displacement (PD) meters offer the ultimate in measurement accuracy for custody transfer of petroleum product, aviation fuels, LPG and broad range of industrial liquids. LC meters incorporate aunique design, presnting 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 nometal-t0-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-product 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 with choice of stock or custom elbows/ fitting provides unequaled mounting flexibility to meet your installation requirement
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 perform with equal accuracy for forward or reverse flow. M and MA Series meters compact design and multiple unlet/ outlet flange configurations provide unmacthed 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 ecternally subjected to the sane system pressure, Due to the low pressure drop inherent to the LC meter, it is often posibble to satisfactorily meter higher viscosity product through a smaller LC meter than its competitive equivalent. Pressure drop through meter depends on product temperature, viscosity and flow rate. When metering a liquid, the pressure drop will increase as viscosity inreases. Illustrated below is the pressure loss vs flow rate curve for an M-60 meter at 600 GPM on dafety solvent (for additional pressure loss data, consult factory)
