Mechanical Rotary Gas Oil PD(Positive Displacement) Flow Meter
It is spiral rotor flow meter ,one kind of Positive Displacement Flow Meter, it can output 4-20mA standard analog signal and pulse , it has local indication, totalizer flow, digital communication, field modification and measure parameters, different power supply function, it is widely applicable in petrol, chemical, power supply, pharmacy, food, water treatment industry etc.
(1) Defination : LLT series dual spiral rotor engine oil , heavy oil ,gas 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.
