　　2、 Product Features

　　Adopting a new type of sensor, with low starting flow rate, small pressure loss, good anti vibration and anti pulsating flow performance, not easy to corrode, good reliability, and long service life;

　　Adopting a new type of microprocessor and high-performance integrated chips, with high computational accuracy, powerful overall functions, and superior performance;

　　Adopting advanced low-power high-tech, the whole machine has low power consumption. It can operate on both internal battery power for a long time and external power supply;

　　According to the flow frequency signal, the instrument coefficient can be automatically linearly corrected in eight segments, which can improve the calculation accuracy of the instrument according to user needs.

　　3、 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.

　　4. Keep the filter unobstructed. The filter is blocked by impurities, which can be judged by the increase in the pressure gauge reading difference at its inlet and outlet. If there is a blockage, it should be promptly eliminated, otherwise the flow rate will be severely reduced.

　　5. For high flow trade settlement measurement, in order to ensure the accuracy of the flowmeter, it must be regularly calibrated.
