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.

Shanghai JSN Micro Flow Meter Co., Ltd. is the second manufacturer ofmicro Oval gear flow meter in China. It is developed by Tu engineer (formerSiemens senior engineer) with independent intellectual property rights. Theproduction and processing equipment fully adopts Siemens CNC machining centerto ensure the minimum flow 0.1ml / min, which is rare in the world, theaccuracy of over 90% of peers. We can do more temperature 200C, the pressurecan be customized to 1000bar, many customers use it, but also unbelievable.Also domestic Most of the flowmeter use a year after the new calibration, butthe base depth meter after hundreds of conditions of medium test, the servicelife of more than 8 years, and without secondary calibration, since theestablishment of the base depth instrument Instrument determined to beworld-class flow meter, breaking the monopoly of international brands in themirco flow meter industry, so that customers can buy in the country realGerman-made quality flow meter.

The Ovalgear flow meter consists of a metering box and a pair of gears mounted in themetering box. It forms a sealed initial moon cavity with the upper and lowercover plates as a unit of calculation of the primary displacement. When themeasured liquid enters the flow meter through the pipe, The pressure differencegenerated at the outlet pushes a pair of gears to continuously rotate, and theliquid measured by the initial cavity is continuously delivered to the outlet.The product of the number of rotations of the gear and four times of eachdisplacement is the measured liquid flow rate. The total flowmeter is mainlycomposed of a housing, a counter, a gear and a coupling (magnetic coupling andaxial coupling).

Commonfault causes, troubleshooting

a. Thegear does not rotate: The gear is jammed by debris, the gear and cavity need tobe cleaned, and the filter is cleaned or replaced.

b. Thesmall flow error is too large: The flowmeter is installed in the wrongdirection, the best position goes up and down, or there are impurities to blockthe gear and need to be cleaned.

c. Theflow error is too large: The actual use flow range is less than or far greaterthan the flowmeter range. The corresponding flowmeter must be selected.

d. Noflow sensor signal: The gear is stuck or the circuit is connected incorrectlyor the circuit is damaged. The gear and cavity must be cleaned, or the circuitmust be correctly connected or replaced.
