Abstract:
An apparatus includes a transceiver configured to generate a signal and receive a plurality of reflected signals for measurement of a level of a process fluid in a tank. The apparatus also includes a waveguide comprising a probe and a buoyant part. The probe is configured to guide the signal from the transceiver and the plurality of reflected signals to the transceiver. The buoyant part is configured to move with the level of the process fluid at an end of the probe and produce a secondary signal representing the level of the process fluid when a level signal of the process fluid is within an end signal representing the end of the probe.
Abstract:
A method of configuring an electronic level gauge (ELG) includes with an ELG configuration tool including a GUI having a user interface. A processor implements an enhancement algorithm and a simulator. A tank library includes a plurality of tank shapes. The user interface receives application configuration information including a selection of a tank shape, a mounting location for positioning the ELG, and at least one process detail. The simulator generates a calculated strength of a measurement signal reflected from a surface of material in the tank for at least one level. If the calculated strength is ≥ a predetermined strength, proper performance of the ELG is indicated, and if the calculated strength
Abstract:
A method includes obtaining first information defining one or more characteristics of (i) a tank configured to store material and/or (ii) one or more obstacles within the tank. The method also includes estimating one or more false echoes using the first information. The one or more false echoes represent one or more potential reflections of a signal off (i) one or more surfaces of the tank and/or (ii) one or more surfaces of the one or more obstacles. The method further includes providing second information identifying the one or more false echoes to a calculation algorithm configured to measure a characteristic of the material in the tank.
