Methods and apparatus for hydrocarbon monitoring are provided. An example method (e.g., performed by a monitoring system) includes receiving one or more first downhole measurements including a first speed of sound (SoS) measurement of a flowing fluid at a first location, wherein a pressure of the flowing fluid at the first location is greater than a bubble-point pressure of the flowing fluid; receiving one or more second downhole measurements including a second SoS measurement of the flowing fluid at a second location, wherein a pressure of the flowing fluid at the second location is less than the bubble-point pressure of the flowing fluid and wherein the flowing fluid is a 3-phase fluid mixture at the second location; and calculating one or more phase flow rates of the 3-phase fluid mixture, based on the first SoS measurement, the second SoS measurement, and a measurement of a bulk velocity of the flowing fluid.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for metering water are disclosed. In some implementations, audio energy corresponding to a flow of material in a pipe that meets a threshold audio energy is detected using a sensor of a batter-operated device connected to the pipe. One or more components of the battery-operated device are activated in response to detecting the audio energy that meets the threshold audio energy. Audio data corresponding to the flow of material in the pipe is collected using the sensor in response to detecting the audio energy that meets the threshold audio energy. The audio data is analyzed using a processing component of the batter-operated device to determine one or more events. An indication of the one or more events is transmitted to an external computing system in response to determining the one or more events.

A flow imaging and monitoring system for synchronized management of wide area drainage that includes an interposer for supporting monitoring and management equipment in a manhole, a module for illuminating water flowing in pipes at the base of the manhole, a module for monitoring responses to reflected light, a sealed and rechargeable battery pack, and a data analysis and management system to interpret data streams in real time. The interposer can be adjusted to fit the diameter of the manhole and can be adjusted to be placed under the manhole cover. The module for illuminating the flowing water can be adjusted to generate various frequencies. The support structures for the modules can be adjusted for varying pitch, roll and yaw with respect to the manhole. The data analysis and management system is supported by cloud computing.

A peristaltic pump is disclosed that includes a plunger, a spring, an actuator, a position sensor, and a processor. The plunger actuates toward and away from a tube. The spring biases the plunger toward the tube. The actuator actuates the plunger away from the tube and mechanically engages and disengages from the plunger. The position sensor senses a position of the plunger. The processor receives the sensed position of the plunger and estimates fluid flow within the tube using a first position of the plunger when the actuator is engaged with the plunger and a second position of the plunger when the actuator is disengaged from the plunger.

An apparatus for the continuous remote measurement of the flowrate of water in bulkhead-holder openings for irrigation, characterised in that it comprises a measuring instrument installed at a distance relative to a lower crossbeam which acts as a bulkhead in an opening of an irrigation channel; the apparatus comprises vertical uprights integral with the crossbeam and a transmitter device; the apparatus can be installed at an opening of an irrigation channel so that the vertical uprights can be made to slide inside bulkhead-holder grooves provided in the sides of the opening; the apparatus allows the detection of data including at least the level of the surface of the water at the opening and the transmission of said data to a remote location.

A method monitors an operation of a fluid meter mounted in a fluid-supplying fluid distribution system. Wherein, by use of an ultrasonic transducer, an event, in the form of a noise generated during the operation of the fluid meter or a pressure surge generated in the distribution system, which is not attributable to the flow measurement and which mechanically excites the ultrasonic transducer, is selectively detected and evaluated and, by reference to a result of the evaluation, at least one fluid meter-specific operating property is generated.

A flow monitoring apparatus includes one or plural hydrophones that receive plural sounds transmitted through a tube wall and/or inside a tube, and a controller including circuitry which converts the plural sounds received by one or plural hydrophones to received signals, extracts flow information from the received signals, evaluates flow rate in a tube, and transmits the volume flowing in a tube per unit of time.

A turbidity measurement device for measuring turbidity of a fluid flowing in a flow tube. A first transducer transmits ultrasonic signals through the fluid in the turbidity measurement section so as to provide a first ultrasonic standing wave between the first and second section ends. A receiver transducer receives the ultrasonic scattered response from particles in the fluid flowing through the turbidity measurement section. A control circuit operates the transducers and generates a signal indicative of the turbidity of the fluid in response to signals received from the receiver transducer. Preferably, the device may comprise a second transducer for generating a second ultrasonic standing wave with the same frequency, and further the two transducers may be used to generate a measure of flow rate by means of known ultrasonic techniques. This flow rate may be used in the calculation of a measure of turbidity. Both turbidity facilities and flow rate facilities may be integrated in a consumption meter, such as a heat meter or a water meter.

A device for sensing information relating to the fill level of a container storing fluid, the container being equipped with a fill- and/or discharge line and a fill- and/or discharge fitting provided therein, is equipped with: a microphone positioned on the fill- and/or discharge line, for sensing an acoustic signal as the fluid passes through said fill- and/or discharge line; means for transmitting the acoustic signals sensed by the microphone to an evaluation unit; and an evaluation unit. The evaluation unit has a memory unit storing a characteristic curve containing information relating to the modification of a characteristic parameter according to the container contents, a computer unit determining a characteristic parameter from the acoustic signal sensed by the microphone, a comparison unit comparing the characteristic parameter and identifying information concerning the container contents, and a display unit which visually displays the information relating to the container contents.

A peristaltic pump, and related system method are provided. The peristaltic pump includes a cam shaft, first and second pinch-valve cams, first and second pinch-valve cam followers, a plunger cam, a plunger-cam follower, a tube receiver, and a spring-biased plunger. The first and second pinch-valve cams are coupled to the cam shaft. The first and second pinch-valve cam followers each engage the first and second pinch-valve cams, respectively. The plunger cam is coupled to the cam shaft. The plunger-cam follower engages the plunger cam. The tube receiver is configured to receive a tube. The spring-biased plunger is coupled to the plunger-cam follower such that the expansion of the plunger cam along a radial angle intersecting the plunger-cam follower as the cam shaft rotates pushes the plunger cam follower towards the plunger and thereby disengages the spring-biased plunger from the tube. A spring coupled to the spring-biased plunger biases the spring-biased plunger to apply the crushing force to the tube.
