Mechanical Control Oil Counter Flow Meter
The mechanical control oil counter flow meter is Double Rotator Flow Meter (spiral rotor flow meter), the latest generation of volumetric flow meter manufactured by our company,as it adopts a pair of helical rotors with special tooth profile, it has prominent characteristics of no pulse,extremely low noise, high precision, high reliability, big flow and high environment adaptability.
(1) Defination : LLTW series spiral rotor is widely used for engine oil , heavy oil ,crude oil,etc with high accuracy, metrological instrument to measure flow volume of fluid in closed pipeline continuously or instantaneously,
(2) Instructure : Composed of measuring body, a pair of spiral rotor, transmission components and registry unit.
(3) Advantage :High accuracy, large measurable flow range and small pressure loss, good adaptability to viscosity, steady operation, none pulsating flow, easy installation, and is able to locally display total volume, instantaneous flow rate or remote monitor with pulse or 4-20mA signal.
