A sand separation system and method for operating a sand separation system, in which the method includes separating sand from a fluid using a separator. The method includes, signaling for a blowdown unit to blowdown the separator, opening one or more blowdown valves of the blowdown unit coupled to the separator in response to the signaling, so as to blowdown the separator, and receiving the sand from the separator into a sand disposal unit. The sand passes through the one or more blowdown valves that are opened. The method includes measuring a weight of at least some of the sand that was separated in the separator using a load cell of the separator, a load cell of the sand disposal unit, or both, and determining a blowdown interval for subsequent blowdown operations of the separator based in part on the weight of the sand.

Method and system for detecting a cleaning process in a radar level gauge configured to determine a fill level of a product contained in a tank, the radar level gauge comprising a transceiver configured to provide a transmit signal, S.sub.T, to be propagated towards the product by a propagating device, to receive a reflected signal, S.sub.R, resulting from a reflection of the transmit signal at a surface of the product, and to determine a fill level in the tank based on the received reflected signal, wherein the method comprises: at a measurement position above the fill level and a known distance from a reference position near a ceiling of the tank, determining a difference in signal amplitude between at least two different fill level measurements; and if the determined difference in signal amplitude exceeds a predetermined threshold value, determining that a cleaning process is ongoing in the tank.

A fixture for flooding detection that includes a communication interface; a processor; and a computer-readable storage media coupled to the processor and having instructions stored thereon which, when executed by the processor, cause the processor to perform operations comprising: receiving, from a first sensor, a first signal indicative of a water level at a location within a facility, determining, based on the first signal, the water level at the location within the facility, determining a shut-off condition based on the water level at the location within the facility reaching a first predetermined height, and transmitting, via the communication interface, a shut-off signal to at least one water inlet at the location within the facility.

A system includes a beverage sensor to distinguish one or more beverage states and to communicate the distinguished one or more beverage states to a processor as gameplay control inputs to the game.

The present disclosure relates to a method for testing a brake fluid sensor of a vehicle braking system, wherein the brake fluid sensor can indicate the fluid level in the fluid reservoir, wherein the method has the following steps: (1) Altering the fluid level in at least one region of the at least one fluid reservoir by means of at least one braking force generating device; and (2) Detecting whether the at least one brake fluid sensor emits a signal indicating the modified fluid level in the at least one region of the at least one fluid reservoir.

A bin volume predictor can receive data characterizing measurements of a temperature at a plurality of temperature sensors of a temperature sensor cable that is positioned to extend along a height of the storage bin in an interior of the storage bin and data characterizing measurements of an ambient temperature of an exterior of the storage bin. The bin volume predictor identifies, based on the measured temperature for temperature sensors in the interior of the storage bin, a topmost covered temperature sensor of the temperature sensor cable. Moreover, the bin volume predictor determines, based on the identified topmost covered temperature sensor, an amount of material stored in the storage bin.

Disclosed herein is a telemetric fitting for a liquid-level gauge, the telemetric fitting being configured to derive liquid-level information from the liquid-level gauge when attached thereto and wirelessly transmit at radio frequencies the liquid-level information.

An automated sand separator discharge system includes a sand separator disposed downstream of a wellhead, an inlet conduit for transporting a process stream to the sand separator, a fluid outlet conduit for transporting a liquid and gas stream from the sand separator, a sand discharge conduit for removing sand from the sand separator, first, second, and third valves disposed along the sand discharge conduit, a first transducer connected between the first and second valves and operative to measure pressure in a portion of the sand discharge conduit and to produce a pressure reading, and a control panel operatively connected to the first, second, and third valves and the first transducer, the control panel being programmed to initiate and terminate discharge of sand from the sand separator, and to determine if the first and second valves are sealing completely when closed.

A water gauge for on-site monitoring and early warning includes an alarm part, a control part and a retractable part. The retractable part is fixedly connected with the alarm part at the top, and the control part at the bottom; the alarm part is electrically connected with the control part through a wire; the control part compares the water level measured by the retractable part with a preset threshold, to determine whether the alarm part needs to give an alarm. When the water on the road rises to the warning line of 30 cm set on the water gauge during a rainstorm, the warning light on the top of the water gauge will start to flash, and the water gauge will give an alarm through the speaker, reminding the pedestrians and vehicles not to pass the section for the time being.

A tank valve system comprises a main valve body, an overfill protection device (OPD), a gauge drive apparatus and a fuel level indicator. The OPD and gauge drive apparatus are configured to both be inserted through a narrow neck of a fuel storage tank prior to connecting the valve body to the neck. The valve body includes a primary fuel channel and a shuttle interface channel. The OPD includes an overfill float driving an overfill shutoff valve for controlling fluid flow from the primary channel into the tank. The gauge drive apparatus includes a gauge float, a shuttle, and an elongated extension body. The gauge float is movable with respect to the extension body between an uppermost position and a lowermost position, thereby driving the shuttle. The shuttle has a gauge actuation portion transportable within the shuttle interface channel to thereby actuate the fuel level indicator.
