摘要： A loop powered process instrument comprises a control system measuring a process variable and developing a measurement signal representing the process variable. A two-wire circuit, for connection to a remote power source using a two-wire process loop, controls current on the loop in accordance with the measurement signal. A power supply with galvanic isolation is connected to the two-wire circuit and the control system to isolate the two-wire circuit from the control system. The power supply receives power from the two-wire process loop and supplies power to the control system. The power supply comprises a voltage regulator receiving loop power and developing a regulated output voltage. A current switching circuit receives the regulated output voltage and drives a primary of a transformer. A secondary of the transformer is coupled to the control system. A voltage shift control includes an isolator circuit driven by the control system for controlling voltage supplied by the voltage regulator.

摘要： There is disclosed a radar transmitter for emulsion measurement comprising a probe defining a transmission line for sensing impedance. A first excitation circuit is connected to a top of the probe for generating downward travelling excitation signals on the transmission line and receiving a reflected signal from the transmission line. A second excitation circuit is connected to a bottom of the probe for generating upward travelling excitation signals on the transmission line and receiving a reflected signal from the transmission line, each of the reflected signals comprising a waveform of probe impedance over time. A controller is operatively connected to the excitation circuits. The controller profiles a section of waveform from each of the excitation circuits and combines information on the sections to determine positions of layers of fluids in a tank, wherein the first excitation circuit provides information about an interface from air into a first fluid layer, and from the first layer to a second layer, and the second excitation circuit provides information about an interface between a lowest layer and the second layer.

摘要： A level measurement instrument comprises an analog circuit for transmitting a pulse signal at a target of interest and receiving reflected echoes of the pulse signal and developing an echo waveform representative of the reflected echoes. A programmed digital circuit is operatively coupled to the analog circuit and comprises a programmed controller and memory. The controller is operatively programmed to identify peaks in the echo waveform and store an active peak list in the memory from a current measurement scan and a buffer peak list from prior measurement scans. The controller is further programmed to match peaks in the active peak list to peaks in the buffer peak list, to select a target peak from the active peak list based on which of the matched peaks have moved, and determining material level responsive to the target peak.
