At presentdomestic Oval gear flow meter structure is complex, bulky, bulky, noisy, smallscale, not suitable for low viscosity liquid, the market is more common withDTO series and OGM series. For these problems the country has been unable toovercome, while the Shanghai JiShen instrument Instrument company oval gear Ovalgear flow meter does not have the above problems, such as the same DN25caliber, our model CX-M25-AL, flow range: 0.5 ~ 100L / M, range of 1: 200 orhigher, and weighs only 1.5KG , While the DTO-25, the flow of 600-6000L / H,range ratio of only 1:10, the weight of up to 23KG. All this due totechnological breakthroughs, our chief engineer Tu workers, he is a formerSiemens senior engineer, the use of equipment It is also Siemens CNC MachiningCenter with cutting accuracy up to 0.001mm, which ensures that we produce highquality flow meters.

A newgeneration of deep base Oval gear flow meter has been officially listed on thenational market in early 2017. This is a newly developed volumetric flowmeteror a positive displacement flowmeter developed by QWEN engineers combiningadvanced technologies both at home and abroad. Deep base of the exhibitionhall, will see the flow meters on behalf of the generation (such as DTO, CX-FM,CX-M, CX-G series), also see the base depth meter in the continuoustechnological innovation. Is characterized by small flow, a large range, highprecision, long life. Through several iterations, the quality of the product isgetting higher and higher, while the price is less than one-third of the importedbrands, can be said that the Shanghai base deep mirco flow meter Successfuldevelopment, domestic customers do not have to worry about delivery, sale andother issues.

The ovalgear flow meter"s metering principle is the same as that of a generalvolumetric flow meter. The gears mesh with the fluid to be transported. Thefluid to be measured enters the chamber through the oil inlet and pushes therotor so that the fluid is continuously divided into the same volume of fluid.Oil port output. For every one rotation of the rotor, the flowmeter outputs thesame volume of fluid in the four metering chambers in the figure. By measuringthe number of revolutions of the elliptical gear rotor, the volume flow throughthe fluid can be obtained.

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.
