A clamp-on ultrasonic flowmeter includes pairs of ultrasonic transducers arranged on an exterior of a pipeline, and an electronic measuring/operating circuit for operating the transducers and for registering and evaluating measurement signals and for providing measured values of volume flow or flow velocity. The pairs are implemented as 1-traverse or 2-traverse pairs. One-traverse pairs are arranged on opposite sides of the pipeline, and 2-traverse pairs are arranged on a same side of the pipeline. At least three pairs are arranged on the pipeline and are distributed peripherally. Adjoining pairs of a number of pairs have an inner angle down to a minimum inner angle (MIA) between one another measured about a pipeline axis, which minimum inner angle obeys the following relationship:

MIA=360°/(T*N*F(T,N))

with T as number of traverses and F(T,N)=0.38+0.62*T+(0.048−0.01*T{circumflex over ( )}2)*(N−2){circumflex over ( )}2.

A system includes upstream process equipment and downstream process equipment. The upstream process equipment is configured to transmit a predetermined fluid to the downstream process equipment. A manually operated valve fluidly couples the upstream process equipment to the downstream process equipment. A removable ultrasonic wireless flow meter is coupled to piping downstream from the manually operated valve. A control system is coupled to the manually operated valve and the removable ultrasonic wireless flow meter. The control system determines an optimum time and speed to actuate the manually operated valve using a predictive model based on a valve size of the manually operated valve, a valve age of the manually operated valve, fluid type, a criticality index of the manually operated valve, a measured flow rate from the removable ultrasonic wireless flow meter, and corresponding coefficients.

Flow meters are disclosed that provide improved measurements of fluid flowing through fan coils. A flow meter includes a body that defines an inlet, an outlet, and a flow path extending along a longitudinal axis between the inlet and the outlet. The flow meter also includes transducers coupled to the body and exposed to the flow path defined by the body. The transducers are configured to transmit and receive a signal travelling through the flow path to measure a flow rate of fluid of the fan coil. The flow meter also includes one or more reflectors coupled to the body and exposed to the flow path defined by the body. Each of the one or more reflectors has a flat reflective surface that is exposed to the flow path and is configured to reflect the signal to relay the signal between the transducers.

A system for detecting characteristics of a fluid includes a sonic sensor. The sonic sensor includes a transducer, a transduction surface, and an acoustically reflective pad member. The transducer may be contained within a probe body, and the transduction surface may be an element of the probe body. A stem may connect the pad member to the transduction surface. The transducer will generate pulses that are transmitted to the pad member via a fluid when the transduction surface and pad member are immersed in the fluid. The system will detect the pulses when reflected and use that data to determine a speed of sound within the fluid. The system may use the speed of sound to determine density, specific gravity and/or stiffness of the fluid. The system may use that determination to assess a level of processing activity of the fluid, such as fermentation activity.
