Level Measurement Expert Level Measurement Guided Wave Radar Beijing GODA Instruments., Ltd.
1.Measurement Principle Principle High frequency micrwave pulses travels alng the detecting cmpnent( steel rpe r rd) and reflects when veaching the prduct surface. The time frm emissin t receptin is prprtinal t the distance between the surface and the reference plane n the instrument. Features GDGW5X equipped with the advanced micrprcessr and unique EchDiscvery ech prcessing technlgy can be used in severe ambience. GDGW5X with extremely lw emissin pwer, can be munted n varius metal r nnmetal vessels, harmless twards the envirnment and human beings. There are multiple ptins availabe in chsing varius prcess cnnectin and detectting cmpnent, which enables GDGW5X t be applied in a brad extent f applicatins, such as high temperature, high pressure, medium with small dielectric cnstant and etc. 1
