摘要:
A vortex flowmeter is disclosed, which includes, among other features, a closed measuring tube, through which a flowable medium that is to be quantitatively measured flows, the medium flowing against a disturbing element that is arranged in the measuring tube. A vibration sensor is arranged downstream in the direction of flow detecting the vortex frequency generated by the disturbing element. An electronic evaluation unit is disposed downstream of the vibration sensor converting it into an electric signal corresponding to the quantitative flow rate or volumetric flow rate. The relative position can be changed between the measuring tube and the disturbing element and/or the measuring tube and the vibration sensor in a signal-optimizing manner.
摘要:
A method and device is disclosed for functional checking of a field device in a field bus system before the commissioning thereof. After installation and connection of the field device, a functional checking algorithm is carried out with regard to meeting relevant connection parameters, whereby commissioning of the field device is permitted when all connection parameters to be checked by the functional checking algorithm are within permitted ranges.
摘要:
Disclosed is a method for diagnosing technical devices, especially pumps and valves, which are arranged within an installation used in the processing industry. According to said method, disturbance variables that affect the devices and influence the service life thereof are detected by means of sensory technology while the data of said disturbance variables is processed in a simulative manner in order to determine the expected service life of each device. Various maintenance instructions which are output along with the expected remaining trouble-free operating time of the industrial installation when a lower service life threshold value of one or several devices has been reached are stored in an expert unit.
摘要:
The invention relates to a method for operating a measuring device, especially a flowmeter, according to the preamble of claim 1. The aim of the invention is to simplify inspection if the sensors have been correctly installed. For this purpose, the installation state is detected by the sensors themselves, i.e. by sensing a corresponding sensor value and comparing it with characteristic data. The result of comparison is electronically evaluated and automatically estimated whether the characteristic data obtained match the comparative data within at least a defined tolerance.
