LC Series Oval Gear Flow Meter

Introduction
LC series oval gear flow meter is the main products of our company. LC oval gear flow meter is one of
the typical displacement meter, used for measurement of pipeline fluid flow under certain pressure. It has
a simple structure, reliable use and high accuracy, flow field has no special requirements for import and
export of the pipe, the viscosity of the measured medium range and the characteristics of the flow range
is very wide. And therefore is widely used in petroleum, chemical industry, medicine, transportation, food
and other industrial and commercial sector of liquid flow detection. LC series oval gear flow meter is
particularly suited to the measurement of oil fuel.

Usage
LC-A type cast iron oval gear flow meter, widely used in all kinds of oil products and for the measurement
of the cast iron material not corrosion liquid medium.
LC-E type cast steel oval gear flow meter, Used for high pressure, low corrosive medium measurement.
LC-Q type cast iron oval gear flow meter, The rotor for aluminum alloy, is suitable for low viscosity, low

LC-U series heat preservation jacket oval gear flow meter

To facilitate easy to solidification of room temperature, or under a certain temperature condensation,
easily crystallized media normal reaction in the pipeline transportation and traffic monitoring, often
need to heating system of the pipeline medium, medium melt and heat preservation. But because the
oval gear flow meter installation place is not allowed to pass by steam (purpose is to prevent damage
meter), therefore we design oval gear flow meter with insulation jacket products, which outside the
meter shell increase insulation jacket, make has solidified medium melt flow meter, and maintain a
certain temperature, so as to ensure the normal operation of flow meter. Oval gear flow meter installed
in front of the filter can also adopt the structure of insulation jacket. Heat preservation jacket in and out
of the structure, generally according to DN15 caliber flange design, special requirements can also
design the user interface. Heat preservation jacket nominal pressure is 0.5 MPa, can also be designed
according to customer special requirements.

LC-D series mechanical quantitative oval gear flow meter

LC – D type mechanical quantitative oval gear flow meter (hereinafter referred to as the flow meter) is a
special flow meter, it is composed of oval gear flow meter, reducer and quantitative counter of three
parts, can accurately measuring the cumulative amount of the liquid, when the number to the expected
value, shut automatically turn on the electric circuit control valve, thus satisfies the requirement of flow
metering control.
