Cast iron LC elliptical gear flowmeter LC cast steel elliptical gear flowmeter

Description :

　　This product uses mechanical measuring elements to continuously divide the fluid into several known volume parts, and measures the total flow volume based on the number of times the measuring chamber sequentially and repeatedly fills and discharges this volume part of the fluid.

　　2、 Characteristics:

　　High measurement accuracy, wide flow range, and good repeatability.

　　All parts are precision machined on the surface, with no casting surface, and the surface is smooth and beautiful.

　　Adopting design, it can be disassembled and reassembled on site without the need for professional personnel, and the original measurement accuracy will not be changed after reassembly.

　　Adopting waterproof design, it is particularly suitable for measuring media with high viscosity, and is insensitive to changes in the viscosity of the measured liquid.

　　On site display can show cumulative flow, instantaneous flow, single flow, etc.

　　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.

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

　　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.

　　7. When starting or stopping, the valve should be opened and closed slowly to prevent sudden impact and to prevent backflow.

　　8. When conducting maintenance, the back cover must not be disassembled to avoid accuracy changes during reassembly and affect accuracy.
