Positive-Displacement Oval Gear Flow Meter for Diesel Fuel Oil Dispenser (Ex Approved)
Overview
Oval meters are instruments used for the continuous and intermittent measurement and control of the pipe liquid flow, which are 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.
Type TLC oval meters are fitted with 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 the flow measurement in the field of petroleum, chemical, chemical fibre, traffic, food industries and commerce, medical and sanitary departments.

The central Ebike Motor of Electric Bicycle is a commonly used component on Electric Bikes. Three types of motors used on power assisted bicycles; Front wheel hub motor, center mounted motor, rear wheel hub motor. The mid mounted motor is a rising star among these three types of motors. After undergoing lengthy technological progress and updates, it has only been developed and used on Electric Bicycles in recent years. Installed in the middle pedal position of the bicycle. It is precisely because of the characteristics and installation location of the central motor that we usually apply it to Lithium Battery mountain assisted bicycles. Because off-road cycling enthusiasts may not always have flat mountain roads, and may even be very bumpy. Riding is quite laborious, so there is an urgent need for external force to provide instantaneous main thrust. Neither the rear wheel hub motor nor the front wheel hub can play this effective role, so the central motor is called the best choice for Assisted Electric Mountain Bicycles.
