Ovalgear flow meter  is widely used inpetroleum, chemical and hydraulic industries due to its advantages of highprecision, simple installation, stable performance and goodrepeatability.However, the Oval gear flow meter that can be produceddomestically can only be applied due to the impatience of high pressure In thelow pressure occasion, the high pressure measurement occasion can only rely onthe foreign imported high pressure flowmeter.Therefore, the research of thehigh pressure Oval gear flow meter will help to expand the domestic applicationof the Oval gear flow meter and promote the development of the domestic flowmeasurement. Deep instrumentation independent research and development of the Ovalgear flow meter pressure up to 1000bar, it can be said has reached a higherlevel in the world, and obtain measurement certificate.

Oval gear flow meter, belonging to a type of volumetric flowmeter,cylindrical shape, with import and export, according to the media with a customfilter. Small size, light weight, easy installation, compact structure, withouttoo much maintenance; other The range ratio is very wide, generally more than1: 100, the minimum flow rate can be measured to 0.3ml / min; and thelinearization accuracy can reach 0.5% FS of full scale, so the use is very wideand can be used for measuring, regulating, controlling and distributing Highand low viscosity, or corrosive liquids, and there are health-type,explosion-proof for a special environment.

Componentsand principles of the Oval gear flow meter - The measurement part of the flowmeter consists of two intermeshing gears and its housing (metering chamber).The measured medium mass per revolution of the gear is half-moon-shaped 4times, in the mirco flow meter hemispherical volume under certain conditions,as long as the measured gear rotation speed n, we can know the measured mediumflow.

What is the reason why the tiny gauge flow meter is larger than the actual value? the reason:1. The flow has a large pulse.2. The medium is mixed with gas.3. Medium viscosity is too large.Treatment measures:1. Reduce the pulsation of the flow in the pipeline.2. Install degasifier.3. Recalibrate, replace the adjustment gear pair and correct it.
