Fenghui Instrument LC-25 Elliptical Gear Flow Meter

Description :

　　Fenghui Instrument LC-25 Elliptical Gear Flow Meter

　　This product has the advantages of simple structure, reliable use, high accuracy, low pressure loss, less affected by changes in liquid viscosity, large range, and easy installation. This series of flow meters is mainly used in industries such as petroleum, chemical, and oil products.

　　1、 Characteristics:

　　1. Flow measurement is independent of the flow state of the fluid and has a wide measurement range.

　　2. The higher the viscosity of the medium, the smaller the amount of leakage from the gear and measuring space gap. Therefore, the larger the viscosity of the measured medium, the smaller the leakage error, and the more advantageous it is for measurement.

　　3. The elliptical gear flowmeter has high measurement accuracy and is suitable for measuring the flow rate of high viscosity media.

　　4. There is no need for straight pipe sections before and after the flowmeter, even if the flowmeter is close to valves, bends, reducers, or expanders, there is no need to install straight pipe sections.

　　5. High measurement accuracy: 0.2 and 0.5 levels.

　　6. It can measure various oils and non corrosive liquid media for cast iron.

　　2、 Technical parameters:

　　1. High measurement accuracy: 0.2 and 0.5 levels.

　　2. Temperature of the tested medium: -10 ℃~+60 ℃ 100~280 ℃

　　3. Power supply (required for output signal): DC24V; DC12V

　　4. Output signal (only one type of output signal can be selected):

　　a) No output signal

　　b) 4~20mA output

　　c) Pulse output

　　d) RS485 communication

　　5. The mechanism is simple, sturdy, and reliable in operation.

　　6. Especially suitable for measuring media with high viscosity, and insensitive to changes in the viscosity of the measured liquid.

　　7. Easy to install. There is no need for straight pipe sections before and after the flowmeter, even if the flowmeter is close to valves, bends, reducers, or expanders, there is no need to install straight pipe sections.

　　8. TLLC-a type cast iron elliptical gear flowmeter is widely used for measuring various oil products and non corrosive liquid media of cast iron.

　　9. TLLC-e type cast steel elliptical gear flowmeter is used for measuring high-pressure and low corrosive media.

　　10. TLLC-b is widely used for the measurement of highly corrosive liquid media, such as acids, bases, salts, and organic compounds.

　　11. In order to prevent the gears of the flowmeter from getting stuck by impurities, a filter must be installed upstream of the flowmeter.

　　12. Explosion proof grade: ExiaICT6

　　3、 Installation and use:

　　1. Before installation, the pipeline should be thoroughly cleaned and a filter should be installed in front of the flowmeter to prevent debris from entering the flowmeter. When the tested liquid contains gas, an air separator should be installed.

　　2. It should be noted that the elliptical gear shaft of the flowmeter must be installed in a horizontal position, that is, the dial must be perpendicular to the ground plane. The valves for regulating flow and starting and closing should be installed separately at the inlet and outlet ends of the flowmeter.

　　3. The arrow on the flowmeter housing should point in the same direction as the liquid flow in the installed pipeline.

　　4. The pipeline for continuous flow and the horizontal pipeline for installing flow meters should be equipped with bypass valves for regular cleaning and maintenance. Flow meters on vertical pipelines should be installed in bypass pipelines to prevent debris from falling into the instrument.

　　5. Under the correct installation conditions, the elliptical gear flowmeter can rotate the counter 180 or 90 degrees as needed for easy reading

　　6. It is strictly prohibited to test flow meters with water.
