An ultrasonic clamp-on flow meter is disclosed. The flow meter comprises a moulded coupling element (9).

Methods and systems for measuring a fluid flow comprise a plurality of transceivers disposed at predetermined locations distributed along a perimeter around the fluid flow. The transceivers transmit and receive acoustic signals through the fluid flow there between. A plurality of different acoustic paths through the fluid flow are formed between different transceiver pairs. Different time intervals are measured between respective times of transmitting and receiving the acoustic signals; and along the plurality of different acoustic paths. A velocity map of the fluid flow is calculated by fitting the measured different time intervals to a model of the fluid flow. The model of the fluid flow defines a velocity map with different flow velocities in a cross-section plane transverse to the fluid flow.

A flow meter includes: a flat substrate; a housing that houses the substrate and has an open in at least one surface; a cover that covers the substrate and covers an open surface of the housing; a support that supports the substrate and is in contact with the cover and the substrate; and a fixing unit that connects the substrate and the housing, in which, in a first region and a second region formed by dividing the substrate into two parts at a center in a longitudinal direction, the support is disposed in the first region, and the fixing unit is disposed in the second region.

Disclosed is a field device of automation technology comprising a measuring transducer for ascertaining a measurement signal and a measurement transmitter for output of the measurement signal ascertained. The field device has at least one housing of the measuring transducer and/or of the measurement transmitter, in which electronic components of the measuring transducer and/or of the measurement transmitter are arranged, characterized in that the electronic components are embedded in an epoxide polymer foam, which is a reaction product of a self foaming, potting compound comprising at least the following components: 25 to 75 wt-% of a diglycidyl ether resin; at least one amine containing hardening system comprising a Mannich base; and at least one foaming agent, and a method for manufacturing a field device of automation technology.

A sensor device is provided for acquiring at least one flow property of a fluid medium. The sensor device includes at least one sensor housing. At least one electronics module, having at least one flow sensor for acquiring the flow property, is accommodated in the sensor housing. The electronics module is at least partly accommodated in an electronics compartment. In addition, at least one moisture sensor is accommodated inside the sensor housing. The sensor housing has at least one inlet opening for exposing the moisture sensor to a moisture of the fluid medium. The electronics compartment is sealed relative to the inlet opening.

A bearing component of a flow sensor of a domestic appliance has a rotary axle which, in the installed state, is oriented so as to be substantially perpendicular to a flow direction of a fluid channel of the domestic appliance. The flow sensor has a first bearing at each of the opposing ends of the rotary axle, two opposing second bearings being contained in the bearing component. The two second bearings are spaced apart from one another in such a way that, in one state of the bearing component, they are engaged with the first bearings of the flow sensor, at least one arm of the bearing component being elastic, so that a distance between the second bearings can be increased in order to insert the flow sensor between the second bearings.
