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.

Ovalgear flow meter is a new type of volumetric flowmeter, in addition to apositive displacement flowmeter with high accuracy, the flow is not sensitiveto other advantages, there are the following advantages: Wide range, usually inthe flow meter is 10: l, and Deep flowmeter is generally 100: 1, or even 1000:1, the accuracy is still above 0.5%, suitable for high pressure flowmeasurement, the maximum pressure can reach 100Mpa, especially suitable for themeasurement of small flow, the minimum measurement limit can be 0.3ml / min ,Less affected by the viscosity characteristics of the medium, suitable for flowmeasurement under various viscosity conditions.

The measuring part of Oval gear flow meter mainly consists of twointermeshing gears and their housings, and the gear generates the acting momentto make it rotate under the pressure difference of the measured medium. Thegears alternately rotate with one another to drive the measured The medium inorder to half the volume of the unit from import to export row by row, so themirco flow meter discharge per revolution measured volume of medium is half thevolume of 4 times the volume flow through the micro-volume flow meter Q Can befigured out

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.
