    Ordering considerations
    1. Product range selection:
    In order to achieve the best effect of product accuracy, life, stability and other functions, the range selection of the product is calculated by referring to the following formula:
    Range = x (1.2-1.5) times of the maximum system pressure;
    The actual measuring pressure range of the product should be 15% - 80% of the range;

    2. Product power supply and output:
    the output specifications of the product:
    RS485-rtu output;
    RS485-rtu + 4-20mA output;
    When output rs485-rtu, please understand the communication protocol first;

    3. The user should understand the measurement medium characteristics of the product:
    Medium specification, medium temperature, medium purity (whether containing impurities or particles, etc.);

    4. Users should understand the installation environment and installation method of the product:
    Indoor or outdoor installation;
    Ambient temperature;
