  • Patent number: 10140480
    Abstract: A counter to monitor an amount of tool use that includes a fluid passage (23) with an inlet (21) and an outlet (22). A piston (30) and sensor target (50) (e.g., magnet) are positioned along the passage and are biased towards a first position by a biasing member (40). When the tool is not in operation, the piston and sensor target are located at a first position due to the biasing force. When the tool is in operation, fluid moves along the fluid passage. A force applied by the moving fluid on the piston and sensor target overcomes the force applied by the biasing member and moves the piston and sensor target along the fluid passage to a second position. A sensor is configured to sense the sensor target at the second position. A processing circuit (62) determines the tool usage based on the detection of the sensor target at the second position by the sensor.

Based upon the ambient temperature sensor readings, the flow rate sensor and heater may be adjusted to optimize the operation of the system to detect leaks. An alternative embodiment utilizes a single sensor and separate heater which work together to determine heat propagation times which in turn is used to calculate flow rate. Based on the sensor readings, the flow may be adjusted to prevent damage and leaks by relieving the system of excess pressure.

  • Patent number: 9035781
    Abstract: A gas appliance monitoring apparatus for automatically detecting and alerting to a “gas-out” condition of a gas appliance during operation, and/or for alerting to the presence of prolonged “gas-on” conditions of an appliance. The apparatus utilizes a highly sensitive low loss and low flow gas flow indicator with multiple flow sensors to monitor the gas flow characteristics of the appliance during use. A gas flow analyzer and alarm timing mechanism analyzes the gas flow characteristics and sounds an alarm at the appliance or wirelessly at a remote location upon detection of either of the above conditions. A biasing attraction magnet is incorporated in the fluid flow indicator to offset either the force of gravity or a return spring in low flow/low pressure applications. The piston is sealed for use in high pressure/low flow applications, and provided with a vent hole for residual gas bleed-off upon a stoppage of gas flow.

  • Patent number: 9024767
    Abstract: Apparatus and method for monitoring flow meter operation. In one embodiment, a flow metering system includes a flow meter and a condition monitor. The flow meter is configured to measure volume of fluid flowing through the flow meter. The condition monitor is coupled to the flow meter and is configured to monitor a parameter of operation of the flow meter, and to compare a value of the parameter to a threshold. The condition monitor is also configured to generate an alarm based on the value exceeding the threshold, and to compute, based on the alarm, a confidence level indicating a degree of certainty that the system is operating in accordance with predetermined criteria.

  • Patent number: 9019122
    Abstract: Information in a data store may be efficiently accessed to perform boundary reading processing. In one example, register readings of one or more register channels that are linked to one or more interval channels may be retrieved from the data store to determine whether or not a boundary reading of a time span is missing. If a boundary reading is missing, but a proximate register reading exists, the boundary reading may be estimated from the proximate register reading and at least one interval reading.

  • Patent number: 8983667
    Abstract: A system is provided to control fluid flow in a wastewater treatment system through wastewater level manipulation. The wastewater treatment system may include a wastewater treatment plant connected to a plurality of pump stations by a main. Each of the plurality of pump stations may include a wet well with a pump therein. The system may include a central server in communication with a sensor to sense a level of wastewater within the wet well. The pump may be automatically moved to an on position when the level of the wastewater in the wet well is at or above a first level and may be automatically moved to an off position when the level of the wastewater in the respective wet well is at or below a pump cutoff level. The central server may systematically manipulate the first level to selectively set the level of wastewater within the wet well.

    Abstract: A system is provided for determining whether a damper controlling the flow of make-up air into a kitchen is properly functioning when the kitchen ventilation system is operating. When the kitchen ventilation system is activated, a notification can be provided to a user of the kitchen whereby the user will know whether the damper is open such that make-up air is available for replacing air drawn out of the kitchen by the ventilation system. The notification device can be conveniently positioned in the kitchen so that the user can readily check for proper damper operation when the ventilation system is operating.

    Abstract: An ophthalmic surgical system 10 detects a change in a viscosity of a material being aspirated from an eye 32. The system 10 includes a control module 18 connected to an aspiration pump 20, and a flow meter 19 connected to the control module 18 and the aspiration pump 20. The flow meter 19 provides a flow rate of material aspirated from the eye 32 by the aspiration pump 20. A surgical handpiece 24 connected to the aspiration pump 20 and the control module 18 is inserted into the eye 32 during surgery. The control module 18, during surgery, detects a step change in the flow rate of material aspirated from the eye 32 and the control module 18 further causes the surgical system 10 to alert a surgeon that a change in viscosity of the material being aspirated has been detected indicating that the handpiece 24 has moved from a material of a first viscosity to a material of a second viscosity.
