The pressure sensor is adapted for connection to the pipe. The apparatus includes a mechanism for determining whether the pressure of the fluid in the pipe has negatively deviated from an expected pressure-temperature relationship of the fluid in the pipe. A method for detecting a fluid leak in an isolated segment of a pipe: The method consists of five steps: Step 1, measure the average propagation velocity of the fluid in an isolated segment of the pipeline at time t1. Step 2, measure the pressure of the fluid in the isolated segment of the pipe at time t1. Step 3, measure the pressure of the fluid in the isolated segment of the pipe at time t2 and calculate the change in pressure occurring between t2 and t1. Step 4, measure the average propagation velocity of the fluid in an isolated segment of the pipe at time t2 and determine the corresponding change in average temperature. Step 5, calculate the amount of pressure change due to temperature changes and the amount due to probable leaks.

An apparatus for creating a transverse velocity profile of fluid flowing in a pipe which includes a mechanism in communication with the pipe for obtaining the transverse velocity of the fluid at several different locations by introducing energy into the pipe and analyzing that energy in the pipe. The transverse velocity profile is then formed from the transverse velocity obtained at the several locations. The acoustic energy can be provided along a plurality of diametrical paths in the pipe all of which are in a cross-section of the pipe producing an information signal corresponding to the transverse velocities obtained with a signal processor receiving the information signals and determining the associated transverse velocities.

An apparatus for determining a period of time of an acoustic wave in a fluid in a pipe where the wave is provided to the fluid from the outside of the pipe and a signal is obtained corresponding to when the wave has traversed the pipe and the fluid therein, and signal processing means measures the period of time the wave is in the fluid based on the signal, the signal processing means being in communication with means providing the acoustic wave. Also disclosed is a method and apparatus for determining sound velocity of fluid flowing in a pipe comprising transmitting acoustic energy into the fluid flowing in the pipe such that the energy takes a path through the pipe, receiving the acoustic energy after it passes out of the fluid, measuring the time the energy takes to pass through the fluid, and identifying sound velocity of the fluid from the time measured. The apparatus also allows determination of the temperature of the fluid.

An ultrasonic flowmeter includes a meter body including a flow passage having wetted surfaces through which fluid flow is to be measured. The flowmeter includes a non-stick coating adhered to the wetted surfaces of the meter body. The flowmeter includes a first transducer and at least a second transducer arranged around the flow passage to transmit and receive ultrasonic energy. The flowmeter includes an electronic unit designed to generate and receive electronic signals from the transducers and to process the signals in order to compute information related to the fluid flow rate through the passage. A method for measuring fluid flow with an ultrasonic flowmeter. A method of making an ultrasonic flowmeter.
