LC Series Oval Gear Flow Meter


Introduction

The LC series oval gear flow meter stands as a flagship product within our company. It represents a typical displacement meter, specifically designed for measuring fluid flow in pipelines under certain pressure conditions. Renowned for its simple structure, reliable performance, and high accuracy, this flow meter imposes no special requirements on the import and export of the pipe. It accommodates a wide range of viscosity in the measured medium and boasts a broad flow range.

The LC series oval gear flow meter finds extensive applications across various industries, including petroleum, chemical, medicine, transportation, and food. Its versatility makes it a preferred choice for liquid flow detection in both industrial and commercial sectors. Notably, this flow meter excels in the measurement of oil fuel, making it particularly well-suited for applications in this domain.

Usage

The LC-A type cast iron oval gear flow meter is extensively utilized for measuring various oil products and is particularly suitable for cast iron material that is resistant to corrosion in liquid mediums.
The LC-E type cast steel oval gear flow meter is designed for measuring high-pressure, low-corrosive mediums.
The LC-Q type cast iron oval gear flow meter, equipped with an aluminum alloy rotor, is suitable for measuring low-viscosity and low-corrosion liquids, including gasoline.
The LC-B and C types, both constructed with stainless steel, find wide applications in measuring strong corrosive liquid mediums, such as acids, alkalis, salts, and organic compounds.
The LC-L type, made of aluminum alloy, is a compact oval gear flow meter widely used for measuring low-corrosive liquid mediums, like water.

LC-U series heat preservation jacket oval gear flow meter

To address the challenges posed by media prone to solidification at room temperature or condensation under certain temperature conditions during pipeline transportation and traffic monitoring, it is common to implement a heating system for the pipeline medium. This system ensures that the medium remains melted and adequately heated. However, due to restrictions on passing steam in the vicinity of the oval gear flow meter (to prevent damage to the meter), we have developed oval gear flow meters with insulation jacket features.

This design incorporates an insulation jacket around the meter shell, providing a layer of insulation to facilitate the flow of solidified media and maintaining a specific temperature, ensuring the normal operation of the flow meter. The insulation jacket structure can also be adopted in front of the filter when the oval gear flow meter is installed. The in and out structure of the insulation jacket is typically designed with a DN15 caliber flange, and special interface designs can be accommodated based on user requirements. The nominal pressure for the insulation jacket is 0.5 MPa, but it can also be customized to meet specific customer requirements.

LC-D series mechanical quantitative oval gear flow meter

The LC-D type mechanical quantitative oval gear flow meter, referred to as the flow meter, is a specialized instrument comprising three main components: the oval gear flow meter, reducer, and quantitative counter.

This flow meter is designed for precision measurement of the cumulative liquid volume. When the accumulated value reaches the predetermined quantity, the electric circuit control valve is automatically closed or opened, meeting the requirements for flow metering control.

Oval gear flowmeter Ordering Information




Note:
1. If the oval gear material and shell material are same, no need to note the oval gear material.
2. Material B-0Cr18Ni9Ti; C-0Cr18Nil2Mo2tI
3. Add B before the transmitter, means explosion-proof transmitter.
4.High temperature meter don't need to be with radiator, just note “T”.
