1. Method of using an elliptical gear flowmeter to measure the flow rate of 100 liters of diesel per minute. The elliptical gear flowmeter should be installed, operated, and regularly maintained according to specifications. The specific method is as follows:
1. Installation requirements: The installation of the elliptical gear flowmeter should follow the standard method, and horizontal or vertical pipeline installation should be preferred to avoid measurement errors caused by pipeline inclination or bending. Before installation, it is necessary to check whether the inner wall of the pipeline is smooth to prevent impurities from blocking the gears; At the same time, ensure that the inlet and outlet of the flowmeter are coaxial with the pipeline to reduce pressure loss. Incorrect pipeline examples (such as sharp bends and reduced diameters) should be strictly avoided, otherwise it may affect the stability of gear rotation and lead to inaccurate flow measurement.
2. Preparation before operation: Carefully read the user manual of the Bichang flowmeter, focusing on mastering the gear rotation direction, counter carry rules, and digital display reading methods.
. Bring the manual to the site for easy reference of parameter settings or troubleshooting at any time. Reading and recording: Observe the digital display screen or mechanical counter of the flowmeter and record the current cumulative flow value. Mechanical flow meters need to pay attention to the direction of gear rotation (usually clockwise), and when carrying the counter, it is necessary to confirm whether the digits such as one digit and ten digit are accurate, and the state number will jump to avoid missing or misreading. If it is necessary to m
III. Maintenance points: Regularly check gear wear: The elliptical gear flowmeter measures flow through gear rotation, and gear wear can cause displacement deviation. It is necessary to check the gear meshing condition every 3-6 months.
. If scratches, tooth deformation, or rotational sticking are found on the surface of the gear, it is necessary to replace the gear in a timely manner or contact the manufacturer for repair. Cleaning and blockage prevention: Diesel fuel may contain impurities, and it is necessary to regularly clean the flow inlet filter screen to prevent particulate matter from entering the crescent shaped cavity and affecting the normal rotation of gears. 4. Precautions for Model Differences: Different models of elliptical gear flow meters may have differences in disassembly inspection procedures, counter switch functions, or parameter settings. For example, some models require specific key combinations to enter the setting mode, adjust the displacement coefficient or reset the cumulative value. Before use, be sure to check the model manual to avoid data errors or equipment damage caused by improper operation. Through standardized installation, accurate operation, and regular maintenance, the elliptical gear flowmeter can stably measure diesel flow and meet the measurement requirement of 100 liters per minute.2.
