Flanged diesel fuel flow meter 

General Description

Oval gear 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.
HHLC oval gear 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 fiber, traffic, food industries and
commerce, medical and sanitary departments. 

Structure and 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 time 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.
