LLQ series Intelligent gas lobed rotor (Luo Ci) flowmeter Is a set of flow, temperature, pressure detection function and a body, And temperature, pressure automatic compensation of a new generation of flowmeter, The flowmeter Based on the volumetric The measuring principle of, For accurate measurement of flow through the closed pipe Total gas. Flowmeter based type by the waist wheel flow sensor And flow totalizer (two meter) of two parts. The flowmeter adopts advanced microprocessor technology and micro power consumption of high technology, Of the measured medium Are arranged in the press Automatic tracking compensation operation and temperature, And directly display the standard state(P0=101.325Kpa，T0=293.15K) Total volume.
LLQ series Intelligent gas lobed rotor (Luo Ci) flowmeter Execution machinery industry standard of the people's Republic of China JB/T7385-94 ≤Gas flowmeter≥And the enterprise standard≤LLQ type gas flowmeter≥。
LLQ series Intelligent gas lobed rotor (Luo Ci) flowmeter Widely used in restaurants, hotels and other industries Gas trade settlement, Pipeline gas metering, gas pressure regulating station measurement, industrial and civil boiler gas metering, Can also be used as industrial propane, nitrogen, inert gas and other non corrosive gas standards and metrology.
The accuracy is high, repeatability is good. Internal rotor by the precision machining and balance test, Oil lubrication good, To ensure the accuracy of flowmeter invariant, Long operating life.
