　　2、 Maintenance:

　　1. Before putting the flowmeter into operation, it is necessary to set the instrument coefficient and carefully check to ensure that the flowmeter wiring is correct and well grounded before power can be transmitted.

　　2. Regularly clean, inspect, and recalibrate the flowmeter. Flow meters with lubricating oil or cleaning solution injection ports should be regularly filled with lubricating oil or cleaning solution according to the instructions to maintain the good operation of the impeller.

　　3. Monitor and display the condition of the instrument, and promptly check if there are any abnormalities in the instrument readings.

　　3、 Selection:

　　When selecting a flow meter, users should choose the appropriate model and specifications based on the nominal pressure of the pipeline, high pressure of the medium, medium temperature, medium composition, flow range, and signal output requirements.

　　In order to achieve optimal performance of the flowmeter, the flow rate range of the flowmeter should be within the Qmax range of (20% to 80%), which is more appropriate.

　　The signal output mode of the flowmeter at the factory: working condition pulse signal output (three wire system), standard flow signal (IC card) output, or RS-485 communication output. If other output functions are required, please specify when placing an order.

　　4、 Installation:

　　Sensors can be installed in vertical, horizontal, or any inclined position according to the flow direction indicator;

　　When the pipeline is long or close to the vibration source, supports should be installed upstream and downstream of the flowmeter to eliminate the impact of pipeline vibration;

　　The installation location of the sensor should have sufficient space for the inspection and maintenance of the flowmeter, and should meet the environmental requirements of the flowmeter;

　　Avoid interference from strong external magnetic fields;

　　When installed and used outdoors, there should be a cover to avoid direct sunlight and rainwater erosion, which may affect the service life of the instrument;

　　When conducting pipeline pressure testing, attention should be paid to the pressure measurement range of the pressure sensor equipped on the intelligent flowmeter to avoid damaging the pressure sensor due to overpressure.
