  • Patent number: 9857305
    Abstract: An optical sensor may have multiple detection channels to detect different characteristics of a fluid. For example, an optical sensor used in industrial cleaning and sanitizing applications may have multiple detection channels to detect when a system is both clean and properly sanitized. In one example, an optical sensor includes an optical emitter that directs light into a fluid, a first optical detector that detects light transmitted through the fluid, a second optical detector that detects light scattered by the fluid, and a third optical detector that detects fluorescent emissions emitted by the fluid. The optical emitter and optical detectors can be positioned around an optical analysis area. The optical sensor may include filters that control the characteristics of light detected by each of the optical detectors.

  • Patent number: 9719604
    Abstract: Embodiments include a flow regulating device. The flow regulating device may include a check valve. The check valve can have a first flange, a second flange and a ball seated against a seat defined by the first flange. The check valve is in a closed position when the ball is seated against the first flange. One or more stoppers may be positioned at a distance from the first flange. A fluid may flow through a first orifice and a second orifice defined in the first and second flanges respectively, when the first check valve is in an open position. The fluid lifts the ball from the first orifice, and pushes the ball towards the second orifice. The stoppers abut the ball when the first check valve is in a fully open position.

  • Patent number: 9557270
    Abstract: An optical sensor can include first and second optical emitters configured to emit light into a fluid sample via an optical pathway. Light from the emitters can cause fluorescence from the sample and/or scatter off of the sample. Scattered and fluoresced light can be received by an optical detector in the sensor via the optical pathway, and used to determine at least one characteristic of the fluid sample. A second optical detector can provide reference measurements of the amount of light emitted to the sample. The second optical emitter and second optical detector can be included in an optical emitter assembly removably disposed in the optical pathway of the optical sensor such that the second optical emitter emits light into the optical pathway toward a fluid sample.

  • Patent number: 9464982
    Abstract: An optical sensor may include a sensor head that has an optical window for directing light into a flow of fluid and/or receiving optical energy from the fluid. The optical sensor may also include a flow chamber that includes a housing defining a cavity into which the sensor head can be inserted. In some examples, the flow chamber includes an inlet port defining a flow nozzle that is configured to direct fluid entering the flow chamber against the optical window of the sensor head. In operation, the force of the incoming fluid impacting the optical window may prevent fouling materials from accumulating on the optical window.

  • Patent number: 9441998
    Abstract: Embodiments include a flow measuring system for measuring characteristics of a fluid flow. The flow measuring system can include a pair of rotating members rotating synchronously to the fluid flow. At least one rotating member can include a normally-reflecting portion and a non-normally reflecting portion. The normally-reflecting portion reflects an incident beam in a direction parallel to the normal direction of the plane of the normally-reflecting portion. The non-normally reflecting portion reflects the incident beam in a direction non-parallel to the normal direction of the plane of the normally-reflecting portion. The flow measuring system measures the optical characteristics of a beam reflected by the normally-reflecting portion and determines rotational characteristics of the rotating member. The flow measuring system determines characteristics of the flow based on the rotational characteristics of the rotating member.

  • Patent number: 9383235
    Abstract: Systems and methods for determining a flow rate or volume of fluid. The system includes a positive displacement meter including a plurality of non-contact sensors and gears configured to rotate in response to fluid flow through the meter. The gears may include detectable areas that may be sensed by the plurality of non-contact sensors to determine a rotational direction of the gears. The plurality of non-contact sensors may also be configured to generate respective detection signals indicative of a rotation state of the gears. The controller may be configured to receive the detection signals, determine a current rotation state, and increment a rotational count based on the changes in the current rotation state. The controller may use the rotational count to determine a flow rate or volume of fluid.
