    1.Unique rhombic monolithic double-cavity structure avoids the chamber leakage or fracture caused by the multi-piece structure or welding process of other forms of sensors and increases the overall strength of the sensor part;

    2.It can measure many kinds of medium, such as dry or moist gas, vapor, liquid, etc.

    3.Probe materials have special 1.4528 and ha C4 alloys, specifically for a variety of strong corrosion medium;

    4.Good plugging performance

    5.It can be measured in both directions

    6.Small permanent pressure loss, about 3% of the full scale differential pressure value

    7.It can directly measure the temperature and pressure of the medium, calculate the mass flow rate of vapor and gas and the standard flow rate

    8.Resistance (sensor) components and transmitters are all universal, free exchange, save spare parts costs. Intelligent, with HART communication protocol, can be remote configuration and calibration function.
