How it is selected & specified.
Rod guided wave radar is a focused product family for liquid tanks and bypass chambers where a rigid probe is easier to install and maintain than a cable probe.
WELK confirms probe length, tank clearance, dielectric, viscosity, buildup risk, process connection and material compatibility before quotation.
Rod Guided Wave Radar Level Transmitter is presented as a configurable WELK product family. Final model limits, wetted materials, process connection, certificate and output signal are confirmed from the selected datasheet before quotation.
Radar selection starts from medium dielectric, measuring distance, nozzle size, vapor/foam/dust condition, pressure, temperature and whether the antenna needs purge, aiming or hazardous-area approval.
Rigid rod probes suit clean liquids and bypass chambers where a stable, short-to-medium insertion length is practical.
