The at least one logic circuit is configured to receive, via the I2C interface, a write command to a first memory address of the logic circuit to initiate a first function of the logic circuit. The at least one logic circuit is configured to generate first data in response to the first function. The at least one logic circuit is configured to receive, via the I2C interface, a first read command to a second memory address of the logic circuit. The at least one logic circuit is configured to transmit, via the I2C interface, the first data in response to the first read command to the second memory address.

Methods and systems for providing a resource dispenser status for a resource dispenser associated with a facility. One system includes an electronic processor. The electronic processor is configured to receive a set of signals. The electronic processor is also configured to compare a first signal included in the set of signals to a set of thresholds. The electronic processor is also configured to determine a resource dispenser status based on the comparison of the first signal to the set of thresholds. The electronic processor is also configured to generate and transmit the resource dispenser status to a remote device, wherein the remote device provides the resource dispenser status to a user.

Disclosed herein are devices, systems, and methods for accurately determining fluid level using Ultra Wideband (UWB) positioning or localization. UWB utilizes a radio-frequency (RF) technology to enable the accurate measurement of the time-of-flight of a radio signal and UWB positioning can operate in Time-Difference-of-Arrival (TDoA) mode, Two-Way-Ranging (TWR) mode, and Phase-Difference-of-Arrival (PDoA) mode. The systems disclosed herein include multiple anchor devices having a UWB antenna(s) and positioned in fixed location(s) over the fluid to be measured. The anchor devices serve as reference points for UWB communication with a remote float device, which emits RF signals and floats on the surface of the fluid to be measured. The anchor devices may include, or be in communication with, a processor which receives and/or measures RF signals, generates timestamps, calculates distance(s) between the remote float device and an anchor device, calculates fluid level, calculates an angle-of-arrival (AoA), or any combination thereof.

The disclosed techniques enable the installation of a level sensor capable of continuously detecting a level of fluid in a vessel or tank and capable of being integrated in a larger control system. Advantageously, sensor head of the disclosed level sensor can be installed on existing installations with an existing displacer or float and an existing member or rod. The disclosed techniques thus enable process plants to easily and affordably replace pneumatic level sensors with a more environmentally friendly option.

Sub-resolution measurement of fuel in fuel tank. In an embodiment, data, which comprise discrete fuel levels in a fuel tank and fuel injection rates for an internal combustion engine, are received. The fuel injection rates are integrated over a traversed distance to produce a fuel consumption series, and the discrete fuel levels are clustered over the traversed distance to produce a fuel level series. The fuel consumption and fuel level series are synchronized into a model that is used to generate sub-resolution measurements of fuel levels between the discrete fuel levels.

A septic system level detection system includes a means to detect a fluid level within a septic system that indicates a failure or possible impending failure of a septic system and means to communicate an alert of this indication via electronic messaging media. A digitized record of information related to the identified septic system is stored in a database. Upon receipt of a septic system failure alert, at least a portion of the digitized record of information is transmitted via an electronic communications system network, i.e., a network comprising a telephony network and/or the Internet, to a predesignated address of the network.

An angle detection device, in particular for a fuel filling level detection device includes: a carrier; a cover, which has been connected to the carrier by at least one solder or adhesive connection layer; and a sensor for the contactless detection of an orientation of a magnetic field of a magnet. The sensor has been arranged in an interior space, which has been defined by the carrier and the cover, in particular on the carrier.
