MG8910 Series
●The microwave signal of guided wave radar is transmitted along the guided wave antenna, which can eliminate false echo signal, reduce signal loss, and has high reliability;
●Guided wave radar technology can eliminate the influence of powder, steam, obstacles and turbulence. It is applicable to the level measurement of various shapes equipment;
●No drift, not affected by atmospheric conditions and medium density changes;
●The wetted parts are made of stainless steel and PTFE, which are resistant to corrosive media such as strong acid and alkali;
●Modules are interchangeable, when replacing modules on site needs no calibration;
●Full digital module display;
●Module design and movable parts without disassembly and wear guarantees a long service life;
●Various installation modes, by thread, flange and cylinder side, are easy to operate.
