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.

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 Ovalgear flow meter is a volumetric flow meter. The metering chamber is composed ofupper and lower end caps. The shell is formed by an oval gear rotor. The gearrotor meshes with the rotating shaft to convey the fluid. The permanent magnetarranged in the rotor is used for the detection of the rotor rotation. Twosensor holes are placed on the upper end to cover the detection sensor. Asealing ring is installed between the housing and the upper and lower end capsto prevent leakage of the measurement fluid. The base depth flowmeter is madeof a material with high wear resistance so that the flowmeter Can guaranteehigh precision measurement within the long service life.

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.
