A chemical tank level system for a wellbore chemical injection tank is provided. The system includes a pressure sensor is located downstream of the chemical injection tank where the fluidic pressure is essentially the same as the fluidic pressure at the base of the chemical tank. The pressure sensor sends a signal indicative of the fluidic pressure to a tank level sensor module. The tank level sensor module receives the signal from the pressure sensor. A processor takes a series of pressure sensor signals over a sample window and calculates an average of the signals over a defined time window.

A system and method for continuous measurement of multiple fluids in multiple tanks and computation of physical properties for each of the multiple fluids continuously, which uses a plurality of probes, at least one client device, a master control processor, and a master control data storage. The system and method can use computer instructions for receiving data from the plurality of probes, receiving data from other detection devices associated with the fluid in each tank, mapping received data to a relational database, and comparing mapped data to stored values associated with prioritized alarm functions. The system and method can also use computer instructions for generating alarms to both a display connected with the master control processor and to at least one client device using a network, generating reports associated with each generated alarm, generating an alarm log, and generating a history of actions taken by a user.

Technology relating to a sump pump monitor is provided herein. A sump pump monitor includes a water level sensor to measure a level of water in a pit of the sump pump, an overflow sensor to detect whether an overflow of the water is present in the pit of the sump pump, and a power monitor to monitor electric power delivered to the sump pump. The power monitor is also to transmit one or more signals indicative of an operational issue associated with the sump pump based on the level of the water, the overflow of the water, and the electric power.

A liquid level monitoring system for monitoring the level of liquid in a tiltable tank, which may tilt or rotate in a tilt or rotation plane about a tilt axis. The system comprises a pair of pressure sensors comprising a first pressure sensor for sensing the pressure of the liquid in the tank at a first position located towards the bottom of a tank and a second pressure sensor for sensing the pressure of the liquid in the tank at a second position located a known pre-defined distance above the first sensing wherein the two sensing positions are located on a sensing line substantially orthogonal to and passing through a liquid surface dividing line, said liquid surface dividing line being the line along and extending past the surface of liquid in the tank whose position relative to the tank walls remains the same as the tank tilts about the tilt axis.

A liquid intake tracking device for removable insertion into a beverage container in order to track an amount of liquid consumed, the rate of liquid consumption over time, and to provide alerts to the user. The device connects wirelessly to an application executing on an external electronic device which provides user with liquid consumption data and reports concerning the user's interaction with the beverage container. Methods for tracking liquid intake are also disclosed.

A sensor arrangement for measuring liquid level in a tank can include a housing, a transducer, a couplant and a bracket for holding one or more sensor components in sensing communication with the tank. The bracket can be configured to hold both a tank and one or more sensors, which can include coupling one or both to another structure, such as a vehicle that utilizes the tank as a fuel source.

The device connects wirelessly to an application executing on an external electronic device which provides user with liquid consumption data and reports concerning the user's interaction with the beverage container. Methods for tracking liquid intake include disposing such a device within the container, calibrating the device relative to the container by processing pressure readings while the container is in an empty and full state, detecting changes in pressure within the container after the calibration step, in which the pressure is a function of a proportion of amount of liquid within the container at the time of detection, and wirelessly transmitting the measured pressure information to the external electronic device using a wireless communication module.
