Abstract
An apparatus includes at least one processing device configured to determine an optimal pulse width for obtaining level measurements associated with material in a tank. The at least one processing device is also configured to generate a control signal that causes a transmitter of a guided wave radar (GWR) to transmit a signal having the optimal pulse width. The at least one processing device is further configured to send the control signal to the transmitter. The at least one processing device can also be configured to alter a length of the optimal pulse width in order to reduce false echoes detected by the GWR, reduce a size of an upper dead zone of the GWR, and/or detect a change of impedance to identify a fault of a process connector in the GWR.
