    Abstract: A pulsed radar method of sensing or measuring a product material in a storage tank. A plurality of waveform types are automatically selected based on a power limitation. The pulsed radar signal is transmitted by a programmable transmitter to the product material, wherein the pulsed radar signal is reflected or scattered by the product material to provide a radar signal during an interval of time including a target signal. An initial gain or attenuation is automatically set for a programmable receiver. The programmable receiver receives the radar signal including the target signal during the interval of time, and the target signal is signal processed using a lower attenuation setting as compared to the initial gain or attenuation to determine at least one parameter associated with the product material. The transmitted and received radar signal can also be adjusted according to the measured SNR.

    Abstract: An antenna combination includes a feed-through having an input side including a connector for coupling to a transmission line connector and an output side including an inner cavity attaching to an aperture in a top surface or a nozzle of a tank. A foam filled dielectric rod antenna is coupled to the output side of the feed-through having a nose portion including a sub-portion within the inner cavity and a rod-shaped portion from beyond the inner cavity to an antenna launch end. The rod-shaped portion includes an outer solid dielectric material including a thickness transition region, wherein a thickness of the solid dielectric material decreases toward the antenna launch end to a constant minimum thickness shell region that extends to the antenna launch end. The outer solid dielectric material defines an inner hollow region. A dielectric foam fill material fills the inner hollow region.

    Abstract: An ultrasonic flowmeter (USM) includes a meter body including a pipe section for flowing a fluid therethrough including a first and second ultrasonic transducer, top-works including a housing and a PCB, a controller coupled to the ultrasonic transducers through a transmitter and/or receiver, and an accelerometer and/or an acoustic sensor for sensing a vibration on the pipe section and for providing an output signal coupled to the controller. The electronics are communicatively coupled to the meter body and the housing is mechanically coupled to the meter body. The controller analyzes the output signal to identify ≥1 vibration frequency and compares the vibration frequency to a predetermined sensitive frequency range for the USM. When the vibration frequency is determined to be within the predetermined frequency range, the controller implements an anti-vibration operating mode by increasing a measurement time when measuring the fluid flow and/or adding additional data processing task(s).
