A pneumatic gauge and pressure control device includes a pneumatic gauge that is manually movable from a neutral position to: (i) a fill position for compressed air to flow from a compressed air source into a system; or (ii) a vent position for compressed air to be vented from the system. The pneumatic gauge can rotate or slide from the neutral position to the fill and vent positions. A method for controlling a flow of compressed air with respect to a pneumatic system includes manually moving a pneumatic pressure gauge from a neutral position to a fill position to cause compressed air to be communicated from an associated compressed air source into the pneumatic system and/or moving the pneumatic gauge from the neutral position or from the fill position to a vent position to cause compressed air to be vented from the pneumatic system.

An example container for collecting bulk material dispensed from a meter during a calibration operation may include a canister comprising an open end to receive bulk material, a coupler configured to releasably couple to a meter, and at least one weight sensor extending between the enclosure and the coupler. The weight sensor may be configured to detect weight of the bulk material deposited into the enclosure via the open end.

A water meter test bench assembly that includes a fluid source, a discharge pipe, and check valve assembly, is provided. The fluid source also provides fluid pressure to move fluid through the at least one meter. The discharge pipe is fluidly coupled to a valve and configured to receive the fluid that passes through the at least one meter. The check valve assembly is attached to the discharge pipe and is in fluid communication with the opening of the discharge pipe. The check valve assembly is open when the fluid pressure from the fluid source moves the fluid through the at least one meter, the valve, and acts on the check valve assembly. When the fluid pressure is reduced sufficient to close the check valve assembly, the fluid is stopped from passing through the check valve assembly.

A system is provided for determining a volume of material milled, or a surface area milled, by a construction machine having a milling drum. The volume of material milled is determined as a function of a cross-sectional area of material to be milled in front of the milling drum and a distance traveled by the construction machine while actively milling. The cross-sectional area is determined in part by direct machine observation of one or more profile characteristics of a ground surface in front of the milling drum. The surface area milled is determined as a function of the width of the area to be milled in front of the milling drum and a distance traveled by the construction machine while actively milling.

A system is disclosed to obtain energy consumption data for an energy monitored property. An identification module is configured to identify, based on first actual energy usage data for the energy-monitored property, one or more daily, weekly, or monthly future time periods when energy consumption is not likely to occur or is likely minimal within the energy-monitored property. A calibration module is configured to transmit electrical signals to open and close at least one of the gas valve and an AC unit switch in accordance with the calibration schedule during a period of time within the one or more daily, weekly, or monthly future periods of time. A computational module may be utilized to calculate a first computed flow rate for the at least one of the gas valve and the AC unit switch. A method and computer program product related to the foregoing system are also disclosed.

A method of monitoring a level of a liquid in a tank of a moveable vehicle includes sensing an orientation of the moveable vehicle relative to a horizontal plane with a vehicle orientation sensor, determining if the orientation of the moveable vehicle is less than an allowable orientation threshold or if the orientation of the moveable vehicle is equal to or greater than the allowable orientation threshold, measuring a level of the liquid in the tank of the moveable vehicle with a liquid level sensor when the orientation of the moveable vehicle is less than the allowable orientation threshold, defining a sensed fluid level value with the controller, and saving the sensed fluid level value in a memory of the controller. The sensed fluid level value is based on the measured level of the liquid when the orientation of the moveable vehicle is less than the allowable orientation threshold.

A method for testing solid acid hydrolysis in a formation. The method includes introducing a test sample into a test cell, where the test sample includes an upper structure, a lower structure, and a solid acid disposed between the upper and lower structures. The pressure and temperature of the test cell are increased to simulate downhole conditions. A velocity of an acoustic p-wave and/or acoustic s-wave is through the test sample is measured while the temperature is increasing from an initial temperature to a final temperature. A temperature of onset of solid acid hydrolysis based on the measured velocity is determined.
