Structural principle
Under the action of the pressure difference between the liquid at the inlet and outlet of the instrument measurement room, a pair of elliptical gears A and B continuously rotate on the shaft and discharge the liquid. By measuring the number of revolutions of the elliptical gears, the total value of the liquid flowing through the instrument can be determined.
2. The LC type elliptical gear flowmeter adopts a magnetic seal connection. The accumulation mechanism uses a character wheel to represent the cumulative reading.
The materials in contact with the measured medium inside the elliptical gear flowmeter include cast iron, cast aluminum, stainless steel, carbon steel, and yellow steel.
LC typeElliptical gear flow transmitterThe elliptical gear flowmeter, which is composed of secondary instruments, has the function of displaying instantaneous flow and cumulative flow from a distance, and can meet the needs of automatic control.
The transmitter has the following characteristics:
1. Adopting advanced contactless communication technology;
2. High precision, less affected by changes in liquid viscosity;
3. There is no need to install a straight pipe section in front of the table;
4. Intrinsically safe explosion-proof, explosion-proof mark: ExiaIAT3
5. The certificate number is GYB5397, which can be used in conjunction with the associated equipment LB867 and can be used in corresponding explosive hazardous areas.
Installment and use
Before installing the transmitter, the surface pipeline should be carefully cleaned of debris. When installing the transmitter, precautions should be taken to prevent debris from falling into the pipeline. Install elliptical gears in a horizontal position as much as possible.
2. A filter should be installed in front of the transmitter to prevent the transmitter from getting stuck in the pipeline due to debris. The filter should be cleaned regularly.
4. The transmitter should be installed at the output end of the pump, otherwise it will also cause an increase in instrument error.
There should be no strong magnetic field around the transmitter that affects the operation of the instrument.
When using the transmitter, the meter should be filled with liquid. There should be no gas mixed in the tested liquid, otherwise a gas separator should be installed.
