General Description of Oval Gear Flowmeter

LC Oval gear flowmeters are instruments used for the continuous and intermittent flow measurement and control of the pipe liquid flow, which are typical of positive displacement flow meter (pd meter), feature large flow range, low pressure loss, for high viscosity fluids, easy installation, high accuracy and can use as high viscosity flow meter, marine fuel flow meter, oil flow meter, high temperature flow meter.,etc.

LC oval flow meters are fitted with mechanical pointer and register which can indicate the liquid flow and totalized flow passing through the pipeline, it is a mechanical flow meter, but it can also be equipped with digital display or analog/pulse output. Customized flow meters can be made of different materials (cast iron, cast steel, stainless steel etc.). LC Oval gear flowmeters are widely used for the flow measurement in the field of petroleum, chemical, chemical fiber, traffic, food industries and commerce, medical and sanitary departments.

We are China Oval gear flow meter supplier provides low cost oval meter, but also with fast delivery time with custom oval gear meter of different technical specifications. Welcome to send your inquiry to us for oval gear flow meter price.
