摘要： A flow meter unit (1) comprising a flow tube (2), a housing (3) and a housing compartment (4), wherein the housing compartment comprises an electronic metering circuitry (5). The flow meter unit uses a first sensor arrangement (6) for determining a fluid flow rate or a fluid flow volume through the flow tube. In order to determine further physical parameters relating to the fluid a second sensor arrangement (7, 20, 30, 32, 60) is placed outside the housing compartment (4), is fluidically and mechanically connected to the flow tube and is in wireless communication with the electronic metering circuitry (5) via a short-range antenna of transmitter and receiver means (8, 8', 8'', 8''') placed in the second sensor arrangement and a short-range antenna (9, 31, 67) placed inside the housing compartment (4). The short-range antenna is positioned at a height in-between a long-range antenna and a bottom wall of the housing compartment. The solution has the advantage that the risk of fluid leakage into the housing when using fluid sensors is reduced and that such a second sensor arrangement is easy to replace or to retro-fit to an already installed flow meter.

摘要： A consumption meter, e.g. a water or heat meter, for measuring a flow rate of a fluid supplied in a flow tube. First and second ultrasonic transducers are arranged at the flow tube for transmitting and receiving ultrasonic signals transmitted through the fluid and operated by a flow measurement sub-circuit for generating a signal indicative of the flow rate of the fluid. A noise measurement sub-circuit operates a sensor arranged at the flow tube for detection of acoustic signals of the flow tube, and being arranged to generate a signal indicative of a noise level of the flow tube accordingly. This sensor may comprise a separate transducer, or the sensor may be constituted by one or both of the first and second ultrasonic transducers. The consumption meter may communicate data representative of the noise level via a communication module along with data consumed amount of water, heat etc. Such consumer noise level measurement at the consumer site allows collection of noise level data to assist in locating fluid leakages in a fluid supply pipe system.

摘要： The invention relates to an ultrasonic flow meter arranged to measure a flow rate of a liquid, the flow meter comprises a flow tube 2, optionally a measurement insert, and two or more ultrasonic transducers 8 which are arranged in transducer inserts 20 to be inserted into the flow tube through openings in the flow tube. The transducer inserts are formed monolithically with the housing as a part of the bottom of the housing. The transducer inserts are in a mount position inserted through the openings in the flow tube to extend into the flow passage so that the surface 15 of the transducer inserts protrude into the flow passage. In this manner, gas bubbles, such as air bubbles, released from the flowing liquid will not rest in front of the transducer insert irrespectively of the orientation of the flow meter in the pipe installation.

摘要： A system and a method for identifying a leak indication in a utility distribution system is de- scribed. A pipe network for supplying a utility to a multitude of service connections includes a plurality of acoustic sensors mounted at the service connections. The acoustic sensors are preferably integrated in ultrasonic flow meters. The method comprises the steps of obtaining information about a time of change (55) of a fluid pressure and then establishing a first noise indicator from the noise measured by the acoustic sensors before said time of change (55), establishing a second noise indicator from the noise measured after said time of change (55); and then correlating one or more first noise indicators and second noise indicators with the fluid pressure to identify service connections subject to leak indications. A leak detection sys- tem based on a mathematical cross correlation of noise indicators and fluid pressure in a fluid pipe system is also described.

摘要： 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.
