Abstract: A flow meter ultrasonically measures fluid velocity in a pipe and ultrasonically transmits fluid flow data along the pipe. An ultrasonic transducer used for fluid velocity measurement may optionally also be used for communication of flow data, and optionally, the ultrasonic frequency for fluid velocity measurement may be the same as the ultrasonic frequency for communication of flow data.

Abstract: Geothermal production monitoring systems and related methods are disclosed herein. An example system includes a production well, an injection well, a downhole pump or a downhole compressor to control a production of a multiphase fluid including steam from the production well, a first fluid conduit to transport the multiphase fluid away from the production well, a surface pump disposed downstream of the first fluid conduit, and a second fluid conduit. The surface pump is to inject water into the injection well via the second fluid conduit. A flowmeter is fluidly coupled to the first fluid conduit. The example system includes a processor to control at least one of (a) the downhole pump or the downhole compressor or (b) the surface pump in response to fluid property data generated by the first flowmeter.

Abstract: An ultrasonic flowmeter includes a measurement flow channel, a pair of ultrasonic transceivers, an amplifier, a propagation time period measuring part, a storage, a flow rate calculator, and a water entry determiner. The amplifier is configured to amplify am ultrasonic wave signal received by one of the pair of ultrasonic transceivers. The propagation time period measuring part is configured to measure a propagation time period between the pair of ultrasonic transceivers by sensing an output signal of the amplifier. The water entry determiner is configured to determine a water entry when a currently set amplification degree is greater than the amplification degree stored in the storage by a predetermined value and a ratio of a currently measured propagation time period to the propagation time period stored in the storage is less than or equal to a predetermined ratio.
