Rosemount Process Radar

Dynamic Vapor Compensation (DVC)

For high pressure saturated steam applications with a varying pressure

and/or temperature, certain models of the Rosemount 5300 Series have a

built-in function (DVC) that automatically compensates for varying vapor

dielectric constants. Option "4V" or "4U" in model code.

It is important that the vapor compensation function is calibrated after

installation.

1. Install unit in pipe/chamber

2. The surface level must be at least 19.7 in. (0.5 m) below the end of the

reflector (It is recommended to empty the pipe/chamber and to ensure it

is free from vapor or condensate remains)

3. Perform the calibration at ambient pressure and temperature conditions,

i.e. when the vapor dielectric constant is close to 1.0

4. Click Calibrate Vapor Compensation, and follow instructions

For more information and instructions, see the Rosemount 5300 Series

Reference Manual (Document No. 00809-0100-4530) section “Dynamic

Vapor Compensation”.
