Mechanical Rotor Flow Meter for fuel oil gas oil hydraulic oil
Working principle Flowmeter consists of shell, piston mechanism and other parts. The counting mechanism is completely separated from the oil by the magnetic transmission, when the instrument access to the pipeline and fuel flow, the inlet and outlet pressure on both sides will push the piston for the rotation action, then the piston connected with the magnetic coupling also Rotation, because the number of revolutions of the piston is proportional to the amount of oil flowing through the meter, the number of revolutions of the piston counted by the counting mechanism is a multiple of the amount of oil flowing through the meter.
(1) Defination : LLT series dual spiral rotor engine oil , heavy oil , fuel oil flowmeter is a highly accurate metrological instrument to measure the flow rate of fluid in 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.
