JCLC Oval Gear Flowmeter

Oval gear meters are instruments used for the continuous and intermittent measurement and control of the pipe liquid flow, which is typical of positive displacement meter, feature large flow range, low-pressure loss, large viscosity range, easy installation, high accuracy and can measure high temperature, high viscosity liquids with easy calibration.

JC-LC oval gear meters are fitted with an on-site pointer indication and roller integration device which can indicate the liquid flow and intermittent flow passing through the pipeline. For the different liquids (acid, alkali, salt, organic solution, etc.), the meters can be made of different materials (cast iron, cast steel, stainless steel, etc.). The meters are widely used for flow measurement in the field of petroleum, chemical, chemical fiber, traffic, food industries and commerce, medical and sanitary departments.

Operation Principle

Oval gear meter is generally comprised of a flow transducer and a counter mechanism. The main part of the transducer is a measuring chamber which consists of a pair of oval wheels and a sealing coupling. The counter mechanism contains speed reduction gears, adjusting device, counter, and pulse transmitter, etc.

In the measuring chamber, a pair of oval wheels and cover plate make a crescent shape cavity which is used as a measuring unit. The oval wheels are rotated by the pressure difference in the inlet and outlet of the meter and drive the inlet liquid through the cavity to the outlet, each revolution of the oval wheels displaces fluid four times the volume of the cavity, the total revolutions of the oval wheels and the revolution rate will be transferred to the mechanical counter, and the total liquid volume and instantaneous flow will be known by the pointer display and the roller integration. The attached signal generator converts the rotary axial angular shift to the pulse signal and then transmits it to the electrical indicator for remote integrated flow and instantaneous flow indication and control.
