email: porter@microflowmeter.com Shanghai JSN Micro Flow Meter CO.,LTD is main flowmetering equipment R&D and production company. The company"s flowmeter andgear pump in scientific research, development, production status.After severaldecades of reform and development, JSN has formed a company model ofindependent development, production, testing, sales and service integration.70% of its products are exported to foreign countries, and have undertakenmajor projects in China, and key enterprises in the industry. Pump supportingprojects. It has been promoted and applied in various engines, polyurethane,dispensing, chemical, lubrication, chemical fiber and other industries inChina.Main products: micro flow meter,oval gearflow meter ,coriolis mass flow meter,electromagnetic flow meter,piston flowmeter,spur gear flow meter,gear pump,gear metering pump etc.

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 is composed of a flow transmitter and a counting mechanism. Themain part of the transmitter consists of a measuring chamber equipped with apair of gear rotors and a sealing coupling. The counting mechanism consists ofa speed reducing mechanism, a precision adjusting mechanism, a counter and apower Pulse transmitter and other components.

What are the precautions for the gear flow meter?
1) When the flow exceeds the specified maximum flow rate, the Oval gear flow meter wear increases with the increase of the rotation speed, and the pressure loss increases sharply, should be avoided. Less than the minimum flow, although still able to measure, but the error increases. Flow meter The starting flow is about 2% of the maximum flow, and the normal working flow is preferably 70%-80% of the maximum flow.
2) Deep-rooted flowmeter is used with various viscosity media from 0.3 ~ 100000cps, different viscosity media will affect the range, the following single must be noted
3) The measured liquid temperature should not exceed the specified value, otherwise, the instrument can not work properly, or even stuck, the counter part is easily damaged at high temperatures. Liquid temperature changes will also cause additional errors in viscosity.
