New Design Mechanical Flowmeter for Liquid with Pulse or Analog Output (JH-OGFM-P)

                                                                        LC Oval Gear Flow Meter
Working principle:
Flow meter 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.
 
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.
