Small size oval gear flow meter fuel positive displacement flow meter mini flow meter
Oval gear meters are instruments used for the continuous and intermittent measurement and control of the pipe liquid flow, which is typical of a positive displacement meter, feature a 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.
