Application
Oval gear flow meter is a target word count accumulated round devices and light
devices to zero volume flow meter is widely used in various industrial areas of the
liquid flow control, applicable to all types of liquid measurements, such as crude oil,
diesel , petrol and so on, with great range and high precision, convenient use and
maintenance of the characteristics of different materials selected to meet the
petroleum, chemical, pharmaceutical, food, metallurgy, electricity, transportation and
other fields of liquid flow measurement.
The working principle and structure
Flowmeter is installed in the metering tank and the measurement of a pair of oval box
gear, with the upper and lower cover an early Lunar sealed cavity (due to rotation of
the gear, so sealing is not an absolute) as a unit of emissions. When measured by the
pipe into the liquid flow meter, due to pressure generated by the Import and Export
Department to promote a pair of differential gears for rotation, the constant
measurement by cavity after the beginning of the Lunar liquid delivery to the exit,
elliptical gear with each revolution time displacement is the product of four times the
measured volume of liquid flow (the principle of Figure 1).

and sub-axial coupling), such as composition (structure see Figure 2).

Flow meter installation
1, should be thoroughly cleaned before installing pipes, and pre-installed in the
flow meter filter to prevent debris entering the flowmeter. Measured liquid containing
gas is air separator should be installed.2, attention should be paid must be the oval gear flowmeter An Chengxin axis
horizontal position, that is, the horizon and vertical dial. Regulation of traffic and start
to close the valve should be installed on the meter side of the Import and Export.
3, the arrows point to the shell flow meter should be installed with the liquid pipe
flow direction.
4, continuous flow of the pipeline, the level of the installation of flow meter bypass
valve should be fitted with pipes, so regular cleaning and maintenance. Vertical pipe
flow meter should be installed in the bypass pipe to prevent debris from falling into
the instrument within.
5, flow meter installed in the right conditions, for ease of reading, according to the
needs of the counter rotating 180o or 90o installation requirements
