Withthe development of society, the state pays more and more attention to theprocess automation instrumentation industry. However, the Oval gear flow meter industryhas been in a vacancy and has been monopolized by major foreign brands such asMax, KRACHT, OVAL, etc. , People have long endured the expensive, longdelivery, the sale can not be resolved in time and so on, such as semiconductorchip cutting a set of equipment on the millions, once the instrument problems,loss unimaginable, the slayer saw these phenomena, Resolutely resigned assenior engineer in the position of Siemens, the establishment of ShanghaiJi-sheng Instruments Co., Ltd., with great concentration on research anddevelopment of gear flow meter. We have Oval gear flow meter has been awarded anumber of certificates, it is no exaggeration to say that Qishen production Ovalgear flow meter For example, many customers replace the OVAL LSF40 with ourCX-M5-AL because it costs less than half of the LSF40, but has twice the rangethan it does and has the same accuracy.

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.

Ovalgear flow meter Through the rotation of the gear cavity, through a series ofdeceleration and speed ratio adjustment mechanism, directly connected with theindicator on the instrument panel, and through the mechanical counter for thetotal display. Or remote display is mainly through The decelerated gear drivesthe permanent magnet to rotate so that the contacts of the spring relay (Hallsensor) are closed or opened synchronously at the same rotation frequency asthe permanent magnet, thereby sending one electric pulse to the other displayinstrument.

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.
