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.

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.

The CX-M and G series gearflow meters consist of a flow transmitter and a display. The oval gear flowmeter metering chamber of the flow transmitter has a pair of elliptical orcircular measuring gears. The gears and the measuring chamber form severalknown volumes. The cavity acts as a metering unit. Under the influence of thedifferential pressure between the inlet and outlet, the gear is driven torotate, and the imported liquid is continuously metered into the outlet aftermeasuring the metering chamber. At the same time, the sensor generates acorresponding electrical signal and sends it to the display section. Afterpartial treatment, the instantaneous flow and cumulative flow of the liquid canbe displayed.

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.
